What’s the Difference Between Thermoforming and Injection Molding

Often, customers in their own hands of the product in the thermoforming process or injection molding process can not tell the difference, or their own design in the end should be used in the injection molding process or thermoforming process?

In the market, the most common plastic parts in the market are thermoforming products or injection molded product. and thermoforming and injection molding are popular manufacturing processes. In fact, for many products, both can vacuum form and also can be plastic injection molding,. That specifically. In which way, do different users have different choices, exactly how is good? Cost, efficiency, and quality are often the most important considerations.

Of course, they are not opposites but complementary. In this blog, we will introduce the Difference Between Thermoforming and Injection Molding in detail.

Different Manufacturing Process

Thermoforming processing

The principle of thermoforming technology is also called the vacuum forming molding process. It is a thermoforming processing method, the use of the thermoplastic sheet, the manufacture of open plastic shell products the method, is the plastic sheet is cut to a certain size after heating and softening, with the help of the heated plastic sheet on both sides of the difference in air pressure and mechanical pressure, so that the deformation of a specific mold profile, after cooling and shaping, and cutting and trimming to complete the thermoforming products process!

Injection molding process

Injection molding is a process in which thermoplastic plastic pellets are heated and molten liquid polymers are, and then the molten plastic is injected into the injection molds through the injection molding machine with high pressure, after a certain cooling time, the plastic is solidified and shaped in the injection molding tooling.

Different materials used

The most significant difference between thermoforming and injection molding is the different materials used. The commonly used materials are PP, PE, ABS, PVC, PET, PS, and other thermoplastic pellets and sheets, while injection molding uses more thermosetting plastics, such as PP, PA, PC, ABS, POM, PE, and other granular raw materials.

Thermoforming uses plates and sheets, so the raw materials will be more expensive compared to injection molding granular materials.

Different design structure of products

Injection molded products are more accurate and can produce complex shapes and structures, while thermoforming products generally produce simpler shapes.

The shape obtained by injection molding is often the final product, and no further processing is required before it is installed or used as a final product. Many details, such as projections, ribs, and threads, can be molded in a single step in injection molding.

Thermoforming products can be produced in simple shapes, with smooth surfaces, are easy to process and assemble, and require post-processing to make holes and remove excess material after the product has been molded. The products mainly include packaging boxes, handicrafts, cards, and so on. Thermoforming products are also widely used in electronics, home appliances, medical and toys.

Different product usage

Due to the different materials and processes, there are some differences between the products made of thermoforming and injection molding. Thermoforming products usually have strong flexibility, impact resistance, and wear resistance, especially suitable for the production of curved and arched products, such as blister packaging boxes, three-dimensional billboards, and so on.

While injection molding products usually have the characteristics of high precision, high strength, good dimensional stability, etc., they are suitable for the production of electronic product shells, automobile parts, industrial equipment, and so on.

Different equipment and tools

Injection molding requires injection molding machines, molds, and other equipment and tools; injection molding machines are mainly divided into vertical injection molding machines, horizontal injection molding machines, two-colour injection molding machines, single-colour injection molding machines, high-speed injection molding machines and so on.

Thermoforming products require equipment and tools such as thermoforming machines and thermal processing devices. According to the different types of pressurization of thermoforming, the mainstream thermoforming equipment is mainly divided into the following three categories:

(1) Vacuum negative pressure forming machine, mainly through the negative pressure vacuum method, so that the plastic sheet is affixed to the mold;

(2) Positive pressure vacuum machine, through the air compressor on the front of the plastic sheet with atmospheric pressure, so that the softened plastic sheet is affixed to the mold;

(3) Positive and negative pressure vacuum molding machines, which form a strong pressure difference between the two sides of the plastic sheet by means of pressurization and vacuum, so that the softened plastic sheet is molded. These three kinds of equipment, each has its own advantages and disadvantages, need to be based on the characteristics of the product to choose the machine.

The parameters of temperature, pressure, and flow rate of injection molding equipment in the process of product processing can be precisely adjusted through the control system, which ensures the precision of product making. At the same time, injection molding equipment consumes less raw materials when processing high-precision products, which also reduces product costs.

In contrast, blister molding equipment is limited in the means of controlling parameters such as temperature, pressure, and flow rate, which is a limitation to the production of products requiring high precision.

Different production efficiency

Injection molding is a kind of high volume production runs plastic processing method. The general production efficiency of injection molding equipment can reach a production capacity of hundreds to thousands of pieces per hour.

At the same time, the degree of automation of injection molding equipment is also very high, and it can quickly complete the processing of products and improve production efficiency. In contrast, the production speed of thermoforming is slower compared to injection molding, and the processing time of the products usually takes several minutes to tens of minutes.

Different costs

A. Tooling Costs

Injection mold according to the complexity of the product, different precision, and mold material at different prices. The commonly used mold materials are S50C, P20, H13, 718H, NAK80, S136, etc., due to the complexity of the product is different, and involves a lot of complexity of the mold processing process than the thermoforming mold, the cost of the relative thermoforming molds are also higher than 5 to 10 times.

The molds used for thermoforming: The molds commonly used for blistering are gypsum molds, aluminum molds, copper molds, wood molds, and steel molds.

The materials used in plastic injection molds are relatively low, and the product structure is simple, so the molds are relatively simple, the materials are cheap, and there are lower tooling costs.

Gypsum mold: the material is gypsum powder, simple to manufacture and amend, usually a single piece of mold only needs 1~3 days, because it is brittle and difficult to dissipate heat, gypsum molds are usually used for the case of having samples handmade samples, not for production.

Aluminum mold: it is made of aluminum through machining and grinding. The aluminum mold has high precision, a smooth surface and is hard and durable, but the price is very expensive, generally used under strict requirements of the product, and ordinary molds can't achieve the precision effect of the use of such molds.

Copper mold: Copper mold should be made with plaster mold first, then take the sample to copper plating, and then fill with gypsum inside.

The copper mold has a better appearance and finish, strength can also reach the usual production requirements, and it is one of the widely used thermoforming molds.

Substitute wood mold: the material is substitute wood, the material cost is higher, needs CNC processing, the manufacturing cycle is short, usually a few hours, easy to sand and punch. The material is also brittle, suitable for sampling in the scene with 3D drawing files, not for production.

Steel mold: generally S45C, S50C, and P20 materials; generally thermoforming, use this type of steel mould.

B. Product costs

The cost of thermoforming vs injection molding is not the same. As the production process of injection molding is relatively simple, the cost advantage of injection molding is obvious when producing large quantities and high-cost products; while thermoforming molding is suitable for smaller production quantities, short production cycles, complex shape products, etc., which is relatively more economical.

The initial cost of injection molds is higher, but the cost per piece is lower when producing large quantities, and the start-up cost of thermoforming is lower, but the cost rises with the increase in production.

In injection molding equipment in the production process, recycling raw material loss will be much less than the vacuum forming molding equipment, especially in the production of larger batches of products, injection molding equipment in the cost savings have obvious advantages.

In addition, injection molding equipment has a higher degree of automation, which does not require much manual operation and also reduces production costs, it's more cost effective for high volume production.

Overall, injection molding is more efficient than blister molding is proven, although the investment in injection molding equipment is larger, in the long run, its production efficiency and production cost advantage will bring more profits and competitive advantage for enterprises.

Conclusion

To sum up, although both thermoforming and injection molding belong to the plastic molding process, there are obvious differences in their materials, production processes, uses, production precision, and product characteristics.

When choosing the molding process, you need to select the most suitable process according to the requirements and characteristics of the specific product. In the actual production and use need to choose the right type of product according to the specific needs.

Injection moulding is a complex operation requiring both hardware (the moulding machine and mould) and software (for manipulating the moulding machine and designing moulds). A simplified installation guide for an injection moulding system. Note that particulars may differ based on the type of machine, mould, and material with which you're working. Step 1: Selection of the Injection Molding Machine You need to choose a machine suitable for the type and size of products you intend to manufacture. This includes considering factors such as: The Power of Clamping Force In injection molding, the clamping force is the powerhouse that ensures the mold remains securely closed during the injection process. Measured in tons, this force guarantees the mold’s close, preventing any misalignments or openings that could compromise the quality of the final product,like flash. Below is the clamping force range for different types of parts: Small parts: 5-50 tons, Medium-sized parts: 50-200 tons, Large parts: 200-1,000 tons, Very large parts: 1,000+ tons Shot Size: A Vital Component The shot size refers to the maximum volume of plastic that the injection molding machine can proficiently introduce into the mold within a single cycle. It's a crucial determinant of the part's size and weight, typically quantified in either grams or ounces. The shot size directly impacts the physical attributes of the end product, underscoring its importance in the molding process. Product shot size = spruce + runner + product + shrinkage General Resins (PPPE, PS,PP,PE)Size injection unit for 20% to 80% of shot capacity Engineered Resins (ABS, PC POM PA):Size injection unit for 30% to 50% of shot capacity A case: The formula is as follows: Shot size = (mould volume) * density x (desired part weight) For example, if the injection mould has a volume of 1500cc, the material density is 0.92g/cc(PP,PE), and the part weight is 70 grams, the shot size would be: Shot size = 1500cc x 0.92g/cc x 70g = 96,600 cubic millimeters (mm3) Influence of Injection Pressure Injection pressure is another critical aspect, as it drives the molten plastic into the cavity of the mold. This force, expressed in psi or bar, must be optimally calibrated. An appropriately set injection pressure ensures smooth and complete filling of the mold, avoiding potential defects that could mar the final product. The Importance of Tie Bar Spacing Tie bar spacing is the distance between the horizontal and vertical bars holding the mold, is a fundamental characteristic of the machine itself. This spacing must be large enough to install the mold. The consideration of tie bar spacing ensures compatibility between the machine and mold, facilitating an efficient and smooth operation. Understanding these key parameters is crucial in optimizing the injection molding process, leading to the production of high-quality, uniform parts. This insight into the intricacies of injection molding provides a robust foundation for making informed decisions in this field, ensuring superior results every time. Step 2: Machine Installation Assuring optimal performance and longevity for any machine is of utmost importance to its overall success and lifespan.

Place Your Machine Near Essential Utilities In order to achieve maximum operational efficiencies and streamline production processes, locating your machine near essential utilities like electricity, cooling water and compressed air may help maximize operational efficiencies as well as ensure smooth production without interruption or hindrance. Doing this will save both time and effort when connecting these utilities directly to the machine as well as ensure no production disruption or hindrance occurs. Prioritizing Electrical Safety To prevent electrical hazards and protect both personnel and machines from potential electrical accidents, grounding of machines should take top priority. Effective grounding measures reduce electrical malfunction risks while guarding against damages to both machines as well as potential harm caused to operators. Hydraulic Systems and Additional Requirements Machines which utilize hydraulic systems must also connect them with an oil reservoir and cooling system in order for proper functioning and longevity of performance to take place. By meeting each specific system requirement diligently, optimal performance and longevity will result. Step 3: Mold Installation Designing and Installing High-Quality Molds for Maximum Performance Mold design and manufacturing require great precision and expertise, using advanced CAD software for design. In order to guarantee seamless integration within machine tie bar spacing and with sufficient strength to withstand clamping force. To achieve optimal performance it's vital that high-quality mold design and installation takes place efficiently and on schedule. Thorough Cleaning for Impeccable Results Before installation, it is critical that a mold be thoroughly cleaned to ensure no contamination or debris are hindering its performance or detracting from final quality of final product. A clean mold contributes significantly towards efficient manufacturing operations as a whole and long term success of manufacturing process. Careful Installation for Seamless Operation Mold installation requires careful handling in order to avoid damage or misalignment during its placement into a machine, using either a crane or reliable lifting device with precision and care. Once loaded into its intended destination machine, attention must be given to ensure optimal functionality by aligning and fastening it securely during production processes. Integration of Utilities for Enhanced Performance In order to optimize a mold's efficiency, connecting any necessary utilities - like cooling lines,hydraulic cylinder and ejector pins- is of vital importance. Cooling lines help regulate production temperatures during production to prevent overheating while protecting product quality while ejector pins assist with efficient product ejection from the mold.

By connecting everything properly, molds can operate seamlessly to deliver consistent and exceptional results every time. Step 4: Machine Setup and Calibration To maximize injection molding machines' effectiveness, fine-tuning their parameters is of critical importance for optimal operation. Temperature, pressure and cycle time all play significant roles in molding processes - these should all be carefully adjusted based on both plastic material used as well as product/mold specifications. Harnessing the Power of Control Software Injection molding machines often come equipped with control software designed to precisely set their parameters, helping operators accurately manage these features. The nature of this software may vary; for instance it could be specially-created by its manufacturer to fit seamlessly with their unique design or it might simply provide general-purpose molding software adaptable across various machine models. Test Cycles: Ensuring Operational Efficiency Prior to commencing full-scale operation, it's imperative that operators test run their machine through several test cycles in order to assess its functioning according to expectations and identify any discrepancies with regards to parameters if any are found that would inhibit optimal performance. This step gives operators an opportunity to confirm this before beginning full-scale production runs. Step 5: Operator Training In order to ensure that operators can effectively utilize machines, it is crucial for them to undergo comprehensive training that covers both safe operation and the resolution of routine issues. By acquiring these essential skills, operators can not only minimize the risk of accidents and injuries, but also improve overall efficiency and productivity. Troubleshooting Techniques: Addressing Common Problems Operators should be well-versed in identifying and rectifying common problems that may arise during the machine operation process. This knowledge empowers them to swiftly resolve issues and minimize downtime, thereby maintaining optimal workflow and preventing unnecessary delays in production. Quality Control Mastery: Ensuring Flawless Finished Products In addition to mastering the intricacies of machine operation, operators must also be trained in quality control procedures to guarantee that the finished products meet the highest standards.

Polyethylene (PE) (PE)

The qualities of polyethylene, a very prevalent type of plastic, might change depending on the density that is selected. Even though injection molding is probably not employed for those applications, it is used for items like food packaging and waste bags. Polyethylene is used in injection molding to create items like toys, home goods, and hard cases like various toolkits and lunch boxes. Although it is a cheap, durable plastic with many alternatives, it has a lower temperature resistance and can be more difficult to mold into precise shapes.

Polyoxymethylene (POM) (POM)

Polyoxymethylene exhibits outstanding stiffness and friction resistance due to its crystalline structure. This makes it perfect for numerous engineering applications, including pulley wheels, bushings, and gears. POM is also used to create stiff pieces like knife handles or eyeglass frames as well as mechanical components for automobiles, locks, and weapons. It can withstand water and oils but not UV radiation or fire.

Polypropylene (PP) (PP)

Polypropylene is a different kind of plastic that is used quite frequently and has several uses. Although it is tough, it retains its shape well and may even be folded repeatedly without breaking. The plastic cap of a condiment bottle that folds open to reveal a pour spout is an illustration of this. It is heat- and food-safe, but it is not flame-resistant. It is used in a variety of different products, including containers and packaging, equipment, toys, and even textile fabric. A lot of PP can be recycled.

It is attractive that the plastic completely contacts the back surface of the shape pits to work with heat move and plastic framing during china injection design service.

Preceding mold conclusion, cartridge radiators in the two form parts 10 and 11 bring the temperature of the shape and plastic layers to over the glass progress temperature of the plastic. When the plastic is mellowed, the shape is gradually shut with low power. As the form gradually shuts, the plastic gradually streams around the capacitor until it is completely epitomized – any abundance plastic in the hole will f1ow out the blaze surface, 24, and into the glimmer well, 23. When the embedded part is completely typified, full clasping power might be applied to the two form parts to make up for shrinkage and accomplish the ideal measurements while the shape is cooled.

The shape plan of plastic precision injection mould factory has some interesting highlights. In the first place, the depressions secure the addition part in the form to stay away from undesired development brought about by the development of the shape or the progression of the plastic soften during the embellishment interaction. Second, this cycle was explicitly intended to give l0w weight on the embedded part by the controlled warming of the mold and relaxing of the plastic followed by the bracing and cooling of the shape. Given this warming and cooling cycle, the form ought to be painstakingly intended to limit the size and thickness of the plates s0 that energy utilization and process duration are limited. Third, this cycle utilized a lash surface and repository to control lashing of excess plastic; it is plainly attractive to choose a measure of plastic stock that limits the measure of lashing while at the same time guaranteeing a completely filled pit. In this plan, the mating lash surface, 24, on the lower form requires a moderately enormous leeway with mating surface on the upper shape half. In the event that this leeway is too little, the pace of the pressure shaping cycle can be restricted by the progression of the plastic dissolve out of the depression.

What’s the Difference Between Thermoforming and Injection Molding

Often, customers in their own hands of the product in the thermoforming process or injection molding process can not tell the difference, or their own design in the end should be used in the injection molding process or thermoforming process?

In the market, the most common plastic parts in the market are thermoforming products or injection molded product. and thermoforming and injection molding are popular manufacturing processes. In fact, for many products, both can vacuum form and also can be plastic injection molding,. That specifically. In which way, do different users have different choices, exactly how is good? Cost, efficiency, and quality are often the most important considerations.

Of course, they are not opposites but complementary. In this blog, we will introduce the Difference Between Thermoforming and Injection Molding in detail.

Different Manufacturing Process

Thermoforming processing

The principle of thermoforming technology is also called the vacuum forming molding process. It is a thermoforming processing method, the use of the thermoplastic sheet, the manufacture of open plastic shell products the method, is the plastic sheet is cut to a certain size after heating and softening, with the help of the heated plastic sheet on both sides of the difference in air pressure and mechanical pressure, so that the deformation of a specific mold profile, after cooling and shaping, and cutting and trimming to complete the thermoforming products process!

Injection molding process

Injection molding is a process in which thermoplastic plastic pellets are heated and molten liquid polymers are, and then the molten plastic is injected into the injection molds through the injection molding machine with high pressure, after a certain cooling time, the plastic is solidified and shaped in the injection molding tooling.

Different materials used

The most significant difference between thermoforming and injection molding is the different materials used. The commonly used materials are PP, PE, ABS, PVC, PET, PS, and other thermoplastic pellets and sheets, while injection molding uses more thermosetting plastics, such as PP, PA, PC, ABS, POM, PE, and other granular raw materials.

Thermoforming uses plates and sheets, so the raw materials will be more expensive compared to injection molding granular materials.

Different design structure of products

Injection molded products are more accurate and can produce complex shapes and structures, while thermoforming products generally produce simpler shapes.

The shape obtained by injection molding is often the final product, and no further processing is required before it is installed or used as a final product. Many details, such as projections, ribs, and threads, can be molded in a single step in injection molding.

Thermoforming products can be produced in simple shapes, with smooth surfaces, are easy to process and assemble, and require post-processing to make holes and remove excess material after the product has been molded. The products mainly include packaging boxes, handicrafts, cards, and so on. Thermoforming products are also widely used in electronics, home appliances, medical and toys.

Different product usage

Due to the different materials and processes, there are some differences between the products made of thermoforming and injection molding. Thermoforming products usually have strong flexibility, impact resistance, and wear resistance, especially suitable for the production of curved and arched products, such as blister packaging boxes, three-dimensional billboards, and so on.

While injection molding products usually have the characteristics of high precision, high strength, good dimensional stability, etc., they are suitable for the production of electronic product shells, automobile parts, industrial equipment, and so on.

Different equipment and tools

Injection molding requires injection molding machines, molds, and other equipment and tools; injection molding machines are mainly divided into vertical injection molding machines, horizontal injection molding machines, two-colour injection molding machines, single-colour injection molding machines, high-speed injection molding machines and so on.

Thermoforming products require equipment and tools such as thermoforming machines and thermal processing devices. According to the different types of pressurization of thermoforming, the mainstream thermoforming equipment is mainly divided into the following three categories:

(1) Vacuum negative pressure forming machine, mainly through the negative pressure vacuum method, so that the plastic sheet is affixed to the mold;

(2) Positive pressure vacuum machine, through the air compressor on the front of the plastic sheet with atmospheric pressure, so that the softened plastic sheet is affixed to the mold;

(3) Positive and negative pressure vacuum molding machines, which form a strong pressure difference between the two sides of the plastic sheet by means of pressurization and vacuum, so that the softened plastic sheet is molded. These three kinds of equipment, each has its own advantages and disadvantages, need to be based on the characteristics of the product to choose the machine.

The parameters of temperature, pressure, and flow rate of injection molding equipment in the process of product processing can be precisely adjusted through the control system, which ensures the precision of product making. At the same time, injection molding equipment consumes less raw materials when processing high-precision products, which also reduces product costs.

In contrast, blister molding equipment is limited in the means of controlling parameters such as temperature, pressure, and flow rate, which is a limitation to the production of products requiring high precision.

Different production efficiency

Injection molding is a kind of high volume production runs plastic processing method. The general production efficiency of injection molding equipment can reach a production capacity of hundreds to thousands of pieces per hour.

At the same time, the degree of automation of injection molding equipment is also very high, and it can quickly complete the processing of products and improve production efficiency. In contrast, the production speed of thermoforming is slower compared to injection molding, and the processing time of the products usually takes several minutes to tens of minutes.

Different costs

A. Tooling Costs

Injection mold according to the complexity of the product, different precision, and mold material at different prices. The commonly used mold materials are S50C, P20, H13, 718H, NAK80, S136, etc., due to the complexity of the product is different, and involves a lot of complexity of the mold processing process than the thermoforming mold, the cost of the relative thermoforming molds are also higher than 5 to 10 times.

The molds used for thermoforming: The molds commonly used for blistering are gypsum molds, aluminum molds, copper molds, wood molds, and steel molds.

The materials used in plastic injection molds are relatively low, and the product structure is simple, so the molds are relatively simple, the materials are cheap, and there are lower tooling costs.

Gypsum mold: the material is gypsum powder, simple to manufacture and amend, usually a single piece of mold only needs 1~3 days, because it is brittle and difficult to dissipate heat, gypsum molds are usually used for the case of having samples handmade samples, not for production.

Aluminum mold: it is made of aluminum through machining and grinding. The aluminum mold has high precision, a smooth surface and is hard and durable, but the price is very expensive, generally used under strict requirements of the product, and ordinary molds can't achieve the precision effect of the use of such molds.

Copper mold: Copper mold should be made with plaster mold first, then take the sample to copper plating, and then fill with gypsum inside.

The copper mold has a better appearance and finish, strength can also reach the usual production requirements, and it is one of the widely used thermoforming molds.

Substitute wood mold: the material is substitute wood, the material cost is higher, needs CNC processing, the manufacturing cycle is short, usually a few hours, easy to sand and punch. The material is also brittle, suitable for sampling in the scene with 3D drawing files, not for production.

Steel mold: generally S45C, S50C, and P20 materials; generally thermoforming, use this type of steel mould.

B. Product costs

The cost of thermoforming vs injection molding is not the same. As the production process of injection molding is relatively simple, the cost advantage of injection molding is obvious when producing large quantities and high-cost products; while thermoforming molding is suitable for smaller production quantities, short production cycles, complex shape products, etc., which is relatively more economical.

The initial cost of injection molds is higher, but the cost per piece is lower when producing large quantities, and the start-up cost of thermoforming is lower, but the cost rises with the increase in production.

In injection molding equipment in the production process, recycling raw material loss will be much less than the vacuum forming molding equipment, especially in the production of larger batches of products, injection molding equipment in the cost savings have obvious advantages.

In addition, injection molding equipment has a higher degree of automation, which does not require much manual operation and also reduces production costs, it's more cost effective for high volume production.

Overall, injection molding is more efficient than blister molding is proven, although the investment in injection molding equipment is larger, in the long run, its production efficiency and production cost advantage will bring more profits and competitive advantage for enterprises.

Conclusion

To sum up, although both thermoforming and injection molding belong to the plastic molding process, there are obvious differences in their materials, production processes, uses, production precision, and product characteristics.

When choosing the molding process, you need to select the most suitable process according to the requirements and characteristics of the specific product. In the actual production and use need to choose the right type of product according to the specific needs.

When making injection molding, it is important to have various safety measures in place to protect both the workers and the equipment. Some common safety precautions in an injection molding plant include: Personal protective equipment: Workers should wear gloves, safety glasses, and other protective gear to minimize the risk of injury for it is easy for workers to contact the hot nozzle,melt material and hot products. Personal protective equipment (PPE) is an important aspect of safety in an injection molding plant. It is designed to protect workers from potential hazards such as chemicals, heat, noise, and machinery. Some common types of PPE used in injection molding include: Gloves: Workers handling hot or sharp components should wear gloves to protect their hands from burns or cuts.Some plastic items are 60 degree when ejected from the injection mold. Safety glasses: Workers should wear safety glasses to protect their eyes from flying debris, chemicals, or hot splashes. Respirators: In some cases, workers may be exposed to fumes or dust (POM injection molding would lead to pungent odor )generated during the molding process. Respirators can help filter out harmful particles and protect workers from respiratory problems. Protective footwear: Workers should wear closed-toe shoes with non-slip soles to prevent slips, trips, and falls. Hard hats: Workers should wear hard hats to protect their heads from falling objects or from bumping into overhead structures. Machine guards: Machine guards are an important safety feature in an injection molding plant. They are designed to physically protect workers from moving platens and hot surfaces on the injection molding machine. There are several types of machine guards commonly used in injection molding, including: Light curtains: Light curtains are safety devices that emit beams of light across the opening of injection molding machine. If the beams are broken by a person or object, the machine will stop closing automatically,wich is very important for big mould,for workers have to go into the machine and stand between 2 mould halves to taks the plastic part. Safety interlocks: Safety interlocks are physical barriers that prevent access to dangerous parts of the injection molding machine. They can be doors, gates, or covers that must be closed before the machine will operate.If the this interlocks dont recover its position,the machine wont work. Barrier guards: Barrier guards are physical barriers that surround the moving parts of the machine to prevent workers from coming into direct contact with them.As to the injection molding machine,it is safe door which separate workers and injection molds. Emergency stop buttons: Emergency stop buttons, or emergency shutdown buttons, are a critical safety feature in an injection molding plant,a very big red button on the control panel. They provide a quick and easy way for workers to shut down the molding machine in the event of an emergency, such as a machine malfunction, operator error, or a fire. Emergency stop buttons should be easily accessible and clearly marked (red for injection machine) so that workers can quickly locate and activate them in an emergency. They should also be connected to the molding machine's control system to immediately stop all movement and power to the machine when activated. Proper ventilation: Proper ventilation is crucial in an injection molding plant to maintain a safe and healthy working environment for employees. During the molding process, various fumes and vapors can be produced from the plastic materials (it is cery common for PA and POM injection molding), solvents, and other chemicals(FR material) used in the process. These fumes can be hazardous to human health if not properly removed from the work area. A good ventilation system should be designed to capture and remove fumes and vapors from the molding area, to prevent workers from breathing in harmful substances.

This can be achieved through the use of exhaust fans, ductwork, and scrubbers, which clean the air before it is expelled from the building. In addition to removing fumes and vapors, proper ventilation can also help regulate the temperature and humidity(Too much water will lead to issues on the PA injection molding surface) in the molding area. This can help prevent overheating and condensation, which can affect the quality of the molded product and create a potential safety hazard. lifting safety: To follow safe lifting techniques, workers should: Use proper lifting posture: Workers should keep their backs straight and bend at the knees when lifting heavy materials(full bag plastic material & mold steel plates) to minimize the risk of back injury. Use proper grip: Workers should use a firm grip and hold the material close to their body when lifting to minimize the risk of dropping the load. Ask for help: Workers should not hesitate to ask for help when lifting heavy or awkward materials to prevent injury. Use proper equipment: Workers should use forklifts,which is used to lift the mold and its components, pallet jacks, and other equipment designed for material handling to minimize the risk of injury and make handling heavy materials easier. Fire protection: Fire extinguishers and other fire suppression equipment are essential for protecting an injection molding and EDM plant from the risk of fire. Here are some key points to consider: Readily available: Fire extinguishers and other fire suppression equipment should be located in easily accessible areas throughout the molding plant and EDM machine,EDM remove steel by sparking, so electrical sparks can easily cause fires - they can be quickly and easily reached in the event of a fire. Proper types: The type of fire extinguisher or suppression equipment needed will depend on the specific materials and conditions in the molding plant. Common fire suppression methods for plastic manufacturing include dry chemical extinguishers, CO2 extinguishers for the fire caused by electricity, and foam systems.. Regular training: Workers should be trained on how to safely operate the injection molding machine, including how to start and stop the machining machine(lathe,drilling machine...), how to set up and adjust molds(mold fitting is a very importsnt step, and how to monitor the production process. They should also be trained on the proper use of PPE, such as gloves, safety glasses, and hearing protection, to protect themselves from potential hazards such as hot surfaces, moving parts, and loud noise. In addition to machine operation training, workers should also be trained on safety procedures for handling raw materials, molded products, and waste. This can include information on safe lifting techniques, the proper storage and disposal of waste materials, and the handling of hazardous materials. FINAL Adhering to these safety precautions and regularly reviewing and updating safety procedures can help ensure a safe and efficient injection molding process.
