Plastic Injection Molding Shapes Tomorrow

Plastic material is melted and then injected into a mold cavity using the industrial process of plastic injection molding to produce a solid, three-dimensional item. This method enables the constant mass manufacture of intricate and accurate plastic components.

Important Elements in Plastic Injection Molding

Melting and injecting the plastic material into the mold consists of a hopper for loading plastic pellets, a barrel for heating the material, and a screw or plunger for forcing the molten plastic into the mold.

Mold: Molds can be created with one or more cavities and are commonly constructed of steel or aluminum depending on the needs of the production process.

Clamping Unit: During the injection process by the injection moulding manufacturer, the clamping unit guarantees that the mold stays tightly closed. The two mold parts are held together by a clamping mechanism, and the necessary force is applied by a hydraulic system.

Ejector System: The ejector system forces the final item out of the mold once the plastic has cooled and set inside the mold. The removal of the molded pieces is made simple and effective by this element.

The Technique of Plastic Injection Molding:

Mold Setup: The injection molding machine is ready for use after the mold has been put inside of it.

Pellets of plastic are fed into the machine's hopper during material loading.

Plastic pellets are heated and melted in the barrel of the injection machine before being injected. The molten plastic is then forcefully pumped into the mold cavity.

Cooling: The plastic inside the mold is solidified by cooling the mold. The thickness of the component and the material has an impact on the cooling time.

Ejection: The ejector mechanism forces the final object out of the mold once the plastic has hardened.

Plastic injection molding advantages:

Precision and Consistency: Plastic injection molding yields components with precise tolerances and reliable quality, making it the perfect process for high-precision goods.

Wide Material Variety: The technique is flexible in that it can handle a variety of thermoplastic and thermosetting materials.

Complex Geometries: Using alternative manufacturing processes would be difficult or impossible for the fabrication of elaborate and complex forms. Injection moulding is the best fit for this.

Introduction to Open-flame rock and roll rotational molding machine

The following is an introduction to the open-flame rock and roll rotational molding machine:

Working Principle

Heating Principle: The machine heats the mold directly by generating an open flame through the burner. The mold is usually made of high-temperature-resistant materials and can withstand the high temperature of the open flame. The burner can adjust the size and position of the flame as needed to ensure uniform heating of the mold.

Rocking Principle: The rocking motion of the mold is achieved through the coordinated action of the main drive motor, crank, connecting rod, and swinging base. The main drive motor drives the crank to rotate, and the crank is connected to the swinging base through the connecting rod. Thus, the swinging base swings up and down with the high bracket as the fulcrum, and then drives the rotational molding mold installed on the swinging base to rock synchronously.

Structure Composition

Power System: It includes a main drive motor and an auxiliary drive motor. The main drive motor is responsible for driving the mold to perform the up-and-down rocking motion, while the auxiliary drive motor drives the mold to rotate axially, enabling the plastic raw materials in the mold to be heated and distributed evenly.

Heating System: It mainly consists of a burner nozzle, an automatic igniter, and a solenoid valve. The burner nozzle faces the side wall of the rotational molding mold and is used to inject an open flame to heat the mold. The automatic igniter can realize the automatic ignition function of the burner nozzle, and the solenoid valve controls the on-off of the gas, thereby controlling the opening and closing of the burner nozzle.

Mold Mounting System: One end of the auxiliary machine's rotating shaft is connected to a flange plate, and one end of the rotational molding mold is provided with a connecting plate. The flange plate and the connecting plate are fixed by screws to achieve the installation and disassembly of the mold, which is convenient for replacing different molds to produce various shapes and specifications of plastic products.

Control System: Generally, a PLC control system is adopted, which can precisely control the rotation speeds of the main drive motor and the auxiliary drive motor to adjust the rocking amplitude and rotation speed of the mold. At the same time, it can also control the ignition time of the burner nozzle, the gas flow rate, etc., ensuring the stability of the rotational molding process and the product quality.

Characteristics

Advantages: The equipment cost is low. Compared with other types of rotational molding machines, such as oven-type rotational molding machines and electric heating rotational molding machines, the open-flame rock and roll rotational molding machine does not require a complex heating chamber or electric heating elements, reducing the manufacturing cost and procurement cost of the equipment. It has a small footprint and a relatively simple structure with a small overall volume, which can save production site space. It is suitable for large and simple hollow products and can produce large plastic products such as large water tanks, storage buckets, and chemical containers. For products with relatively regular and simple shapes, the production efficiency is relatively high. The operation is simple, and the control system is relatively intuitive. Operators can master the operation method of the equipment proficiently after simple training, making it an ideal equipment for beginners in rotational molding.

Limitations: The temperature control accuracy is relatively low. The open-flame heating method is difficult to achieve the same precise temperature control as electric heating, which may cause the local temperature of the mold to be too high or too low, affecting the stability of product quality. The energy consumption is relatively large. The burner uses gas as energy, and the energy cost is relatively high in the long run. It causes a certain amount of pollution to the environment. During the combustion process, a certain amount of exhaust gas and noise will be generated, and corresponding environmental protection equipment is required for treatment. It is not suitable for high-precision products. For some plastic products with high dimensional accuracy requirements and strict surface quality requirements, the open-flame rock and roll rotational molding machine is difficult to meet the production requirements.

Application Areas

Container Products: It can produce various specifications of water tanks, buckets, chemical raw material storage containers, etc. These containers have the characteristics of seamless, uniform wall thickness, smooth inner and outer walls, and no leakage, which can meet the needs of different industries for liquid storage and transportation.

Traffic Facilities: It is used to manufacture traffic anti-collision facilities such as crash barrels and isolation piers. The traffic facilities formed by rotational molding have good toughness and impact resistance and can play an effective cushioning role in traffic accidents.

Water Products: It can produce water floats, buoys, small boats, and other water products. Due to the good water resistance and corrosion resistance of rotational molding products, they can be used in water for a long time without damage.

Hard Chrome Plating: A Reliable Solution for Durability and Wear Resistance

Hard chrome plating is a specialized electroplating process that deposits a thick layer of chromium onto a metal surface to enhance its durability, wear resistance, and corrosion resistance. This process, which involves the use of a chromic acid solution, has become a go-to solution in various industries where component longevity is essential. WWG Engineering offers top-notch hard chrome plating services, with state-of-the-art facilities and plating tanks capable of accommodating both small and large components. Their advanced setup ensures that every part, regardless of size or complexity, receives a high-quality chrome coating to meet specific operational needs.

The Hard Chrome Plating Process

Hard chrome plating is distinct from decorative chrome plating. While decorative chrome is typically applied in thinner layers and is primarily used for aesthetic purposes, hard chrome is applied for functional reasons—mainly to increase the lifespan and performance of machine parts exposed to harsh environments. The thickness of hard chrome plating can range from 25 to 1,000 microns, making it a highly versatile solution for numerous industrial applications.

The process starts by immersing the metal component into a chromic acid solution, where chromium is electro-deposited onto the surface. Electro-deposited chrome is known for its incredible hardness, with typical values ranging between 850 and 1050 HV (63 to 70 HRc). These hardness levels make hard chrome one of the toughest and most durable coatings available, hence the term "hard" chrome.

Key Benefits of Hard Chrome Plating

The advantages of hard chrome plating go beyond its impressive hardness. Here are several key benefits that make it ideal for various industries:

Increased Wear Resistance: Hard chrome is exceptionally resistant to abrasive and erosive wear due to its high hardness and low coefficient of friction. The coating is capable of withstanding repeated contact and movement, making it perfect for components exposed to friction-heavy environments.

Enhanced Corrosion Resistance: Hard chrome offers excellent resistance to atmospheric oxidation, preventing the metal underneath from corroding. Its ability to withstand both oxidizing and reducing agents makes it a top choice for components that operate in corrosive environments.

Self-Lubricating Properties: One of the lesser-known features of hard chrome is its self-lubricating properties. This characteristic reduces the need for external lubrication in some applications, improving efficiency and reducing maintenance costs.

Thermal Stability: Hard chrome is considered a "cold" plating process because it operates at temperatures between 50 and 60°C. This ensures that the physical and mechanical properties of the base material are not affected during the plating process, making it suitable for a wide range of materials and applications.

Repair and Salvage Capabilities: In addition to improving the performance of new components, hard chrome plating is commonly used for salvaging and repairing worn, damaged, or mis-machined parts. Thicker deposits of chrome can restore these components to their original dimensions, allowing them to be reused and extending their operational life.

Common Applications of Hard Chrome Plating

Given its excellent wear resistance, corrosion protection, and other beneficial properties, hard chrome plating is widely used across a broad spectrum of industries. Among the most frequent applications are:

Hydraulic and Pneumatic Piston Rods and Cylinders: Hard chrome plating helps reduce friction and prevent wear on moving parts, extending the life of these critical components.

Molds, Dies, and Screws: In industries like plastic injection molding and die-casting, hard chrome improves wear resistance, helping molds and dies maintain their accuracy and prolonging their service life.

Print Cylinders and Plates: The smooth, hard surface of chrome-coated print cylinders ensures high-quality printing while resisting the wear and tear associated with high-speed printing operations.

Valves, Gates, and Bodies: The corrosion-resistant and wear-resistant properties of hard chrome make it a reliable solution for valves and gate bodies that operate in challenging environments, such as the oil and gas industry.

Mining Equipment: Hard chrome plating is commonly used to extend the operational life of mining equipment exposed to harsh conditions, including abrasive materials and corrosive environments.

Pump Shafts and Rotors: In the pump industry, hard chrome plating ensures that shafts and rotors maintain their dimensional integrity and resist wear, even in environments with high friction and pressure.

Textile Components: The self-lubricating properties of hard chrome make it an ideal material for textile components, reducing maintenance requirements and ensuring smooth operation.

Caps, closures, HDPE containers & corrugation from Om Tech Containers

Based in Haridwar's Sidcul industrial area, Om Tech Containers began as a corrugation firm named Om Packaging in 2003. In 2016, the company entered the plastic packaging segment by forming Om Tech Containers – operating in plastic molding and blow molding. 

Om Tech Containers supplies customized caps and closures to Patanjali, GNC, Bella Vita perfumes, ITC, RSPL, and Toyo Inks and others. Usually not many changes are needed in caps and closures, but when they happen, they can be capital intensive, Khurana, a first-generation entrepreneur, told Packaging South Asia during our recent visit to Haridwar.

The company uses five Milacron machines for injection molding of 150-200 tons as the production cost depends hugely on the tonnage of the machine, he said. For smaller products, they use smaller machines while the heavier machines are for large products and bigger lots. 

In caps and closures, the company manufactures flip-top, regular, CTC, screw and lock break caps, he said. The caps are designed according to the usage of the product.

Om Tech containers manufactures HDPE containers through blow molding on five CMP machines manufactured in India. Its HDPE bottles are recyclable.

“The plastic molding industry is creative. Though the basic product is the same, you can change the design according to requirement. Everyone wants a good design to attract customers,” he said. 

“We source our raw material from Reliance, HPCL, GAIL, and Indian Oil. The prices of raw material in the plastic industry mostly depend on the price of crude oil and the demand-supply ratio,” he added.

Corrugation plants for loyal customers

Om Packaging has one manual and one automatic plant for corrugation in Haridwar, where it makes 1500 tons of corrugated cartons per month, Khurana said.

Its corrugation customers include Patanjali, ITC, Prince Pipes and Fittings, Bella Vita perfumes, Fena and Ghadi detergent powders and Panasonic. “Most of our customers are from the FMCG or chemicals segments and a few from pharma. We have a loyal customer base,” Khurana said. 

The company sends corrugated boxes to Delhi-NCR, Baddi in Himachal Pradesh and Uttarakhand. “We don't supply corrugated cartons beyond 400-500 kms because the freight cost gets higher as it is a volumetric product,” he said.

“We have a good turnover and adding more customers. India's packaging industry is competitive. We are looking to grow in the segments where we are already working. Service and on-time delivery are of prime importance in the packaging industry,” Khurana said. 

The company plans to make PET bottles as there is a huge demand in pharma units, he said. By the end of this year, it plans to add one blow molding and one injection molding machine, he concluded.

Subsequently, the large Angle belt conveyor or screw conveyor will be screened after the material to the next process.

Pelleting and molding: In the pelleting process, Fertilizer Granules Compaction Machine with its unique double-roll extrusion technology, the Sugarcaneis mixed with other organic materials and extrudated into pellets. This step not only enhances the appearance and market value of the product, but also facilitates subsequent storage, transportation, and use. Of course, according to the market demand, some manufacturers will also choose to make the material directly into powder or extrusion into columns.

Drying and cooling: The organic fertilizer after granulation needs to be dried by a roller dryer to reduce moisture content and improve stability. A drum cooling machine is then responsible for cooling the dried particles to the appropriate temperature to avoid nutrient damage from overheating.

Packaging and sale: Finally, with the cooperation of automatic batching machine, conveyor and quantitative packaging scale and other equipment, the dried and cooled organic fertilizer is accurately measured and packaged into bags, ready to be sold to farmers or agricultural enterprises.

The green value of bagasse

The application of Sugarcaneas raw material of organic fertilizer not only realizes the resource utilization of agricultural waste, reduces environmental pollution, but also promotes the improvement of soil structure and the increase of crop yield. It is rich in cellulose, hemicellulose and mineral elements, which can release nutrients slowly in the soil and provide lasting and comprehensive nutritional support for plants.

The application of Sugarcanein organic fertilizer production is a vivid practice of agricultural circular economy. Through advanced organic fertilizer production lines and supporting equipment, we can convert this waste into valuable agricultural resources and contribute to the realization of sustainable agricultural development.

In the exploration of sustainable agriculture and resource recycling, bagasse, which was once regarded as a waste material, is gradually showing its great potential as a raw material for organic fertilizer. Through the careful treatment of organic fertilizer production line, bagas can not only realize waste utilization, but also be converted into nutrient rich organic fertilizer, injecting new vitality into farmland.

The production and processing process of organic fertilizer revolves around the three core links of ripening, dehydration and granulation, and the addition of Sugarcaneadds new vitality to this process. On the Organic fertilizer production line, all kinds of advanced equipment work together to complete this green transformation.

Ripening stage: bagars are first mixed with appropriate amount of water, and regularly turned and aerated by organic fertilizer fermentation equipment -- Windrow Compost Turning Machine. This process promoted the activity of microorganisms, accelerated the decomposition and decay of organic matter in bagasse, and laid a good foundation for subsequent treatment.

Crushing and stirring: The decomposed Sugarcaneraw materials should be treated by a crusher. According to the humidity and characteristics of the raw materials, appropriate vertical or horizontal crusher should be selected for crushing. Subsequently, the Sugarcanewas thoroughly mixed with other organic materials using a blender (vertical or horizontal, uniaxial or biaxial) to ensure an even distribution of nutrients.

Screening and transportation: after crushing and stirring materials, through the roller screen or vibration grading screen for screening, remove impurities, improve product quality. Subsequently, the large Angle belt conveyor or screw conveyor will be screened after the material to the next process.

Pelleting and molding: In the pelleting process, Fertilizer Granules Compaction Machine with its unique double-roll extrusion technology, the Sugarcaneis mixed with other organic materials and extrudated into pellets.
