What is an Injection Molding Machine? Get to know everything about it!

Injection molding is an important industrial technique. Although it is somewhat similar to die casting, but the raw material used in this case are different. Die casting uses metals that melt at extremely high temperatures, whereas injection molding mostly uses glasses, elastomers, and most frequently thermoplastic and thermosetting polymers. Nevertheless, this process is commonly used to create thermoplastic materials. In this method, raw materials are heated to a certain temperature and then injected under pressure into the mould cavity without changing their composition.

What are the main parts of injection molding machine?

The material hopper, barrel, an injection ram/rotating screw type plunger, heating element (heater), adjustable pattern, ejectors, and a mould inside mould cavity are the key components of an injection molding machine.

Injection molding machines typically operate horizontally. A barrel is part of an injection molding machine (cylindrical pipe). At one end of the barrel, there is a hopper. Inside the barrel is a revolving screw or hydraulic ram powered by an electric motor that provides force. The barrel has a heating element (warmer) attached to it that is used to melt the molding compound when it exits the hopper.

Mold cavity linked to the barrel's opposite side. During the entire production process, a movable pattern is used and the mould is situated inside the mould cavity. Typically, copper, aluminum, and tool steels are used to make mould. Distinct types of material moulds have different life cycles. This can be chosen based on your needs.

How does the injection moulding machine works?

Extrusion and injection molding both function similarly, as implied by their names. Using a feeding apparatus, molding material and raw materials are poured into the hopper. Following that, the molding material falls into the cylinder (barrel) as depicted in the diagram due to gravity. The material is melted using a circumferential heater that is mounted on the barrel. When molding compound in powder form enters the barrel from the hopper, it begins to melt, and a revolving screw or hydraulic ram applies pressure to advance the compound into the mould.

In this split mould, which is attached to the other side of the barrel, molten plastic material is pumped into a closed mould. The revolving screw constantly advances the molding material. The hydraulic system exerts pressure. Normal injection pressure ranges from 100 to 150 MPa. Following injection, pressure is exerted for a while or held in place with some force.

The pieces produced when the entire procedure is complete are appropriately cooled. The mould is then opened, and a few ejectors are utilized to remove the part properly and damage-free. The portion mould is reopened after removal. This process is very fast and automatically repeated. Here, it is simple to make pieces with complex shapes. The injection molding process may produce 12–16,000 components every cycle.

The Procedure

-    The process parameter fluctuates based on the circumstances and demands. -    The components made with this method typically weigh between 100 and 500 g. -    A single part's cycle time ranges from 5 to 60 seconds, depending on how the item is made. -    The heating range for molding material is 150 to 350 degrees Celsius. -    The molding machine has an injection capacity of 12,000 to 2.2 106 mm3. -    100 to 150 MPa is the injection pressure. -    From 0.1 to 8.0 MN is the locking force.

What are the advantages of Injection molding machine?

-    The fundamental benefit of this method is that intricately shaped components with thin walls (5–15 mm) may be molded with ease and retrieved from the die without being harmed. -    Injection-molded components offer good dimensional tolerance. -    The main benefit of this method is that it produces far less scrap than certain other methods. -    Investment cast iron and intricately machined pieces compete with parts produced through the Injection Moulding Method. -    In comparison to other procedures, this process has a high production rate.

What are the various types of injection molding machines?

Following are the different types of injection molding machines. Have a look:

Mould Manufacturing Process

The process of manufacturing a mould is a complex one, and it's important to note that not all plastic mould manufacturers use the same methods.

The most common method used by manufacturers is CNC machining, which involves using computer-controlled machines to carve out the shape of your product in thin layers. This technique has been around for decades and allows for greater precision than other methods like EDM (electrical discharge machining) or grinding.

Plastic mould manufacturing is a complex process that involves several steps to create high-quality mould for various industries. The process begins with designing the mould using computer-aided design (CAD) software. This software allows engineers to create a detailed 3D model of the mould, including all the intricate details required for the final product.

Once the design is complete, it's time to move onto the manufacturing stage. The first step in manufacturing is to create a mould base using steel or aluminum. This base is what will hold all the various components of the mould together. The base must be designed to withstand the high pressure and temperature required for the moulding process.

Next, the mould is assembled, which involves attaching various components such as the ejector pins, the sprue bushing, and the runner system. These components are essential for the mould to function correctly during the moulding process.

The next step is to machine the mould. This involves using specialized equipment to create the cavities and cores required for the final product. This process involves a high level of precision, and any errors or imperfections can result in a faulty mould.

Once the mould is machined, it's time to test it. This involves running a trial batch of plastic through the mould to ensure that it produces the desired product. Any issues with the mould or the moulding process can be addressed in this stage.

Finally, after the mould is tested and approved, it's ready for production. The mould is attached to an injection moulding machine, and plastic is injected into the cavities to create the final product. This process can be repeated thousands of times to create a large number of identical products.

Overall, plastic mould manufacturing is a complex and intricate process that requires a high level of skill and expertise. From designing the mould to running production, every step of the process must be executed with precision to ensure a high-quality final product.
