What is Plastic Injection?
Homemade plastic injection is a relatively simple procedure that can be performed by people with sufficient knowledge and skills. Plastic injection is a process of producing plastic parts in which plastic materials are injected into a mold in a molten state and then formed under pressure.
Plastic injection process
Plastic material:
Plastic materials used for injection are initially prepared as beads or muscle prints. These materials can include polyethylene, polypropylene, polystyrene, polycarbonate, polyamides and other types of plastic.
Melting the material:
Plastic materials in an injection machine or melting machine are affected by heat to become liquid. This temperature may vary depending on the type of plastic and the size of the piece.
Injection into the mold:
After melting, the plastic material is pressed into a (usually metal) mold by an injection system. This template accurately determines the shape of the piece. Also, inside the mold there is a cooling system that cools the plastic quickly.
Cooling and doing the process:
After injecting the plastic liquid into the mold, the product is subjected to pressure and heat until the final shape is well formed. Then, the mold is cooled and the product is taken out.
Product Exit:
The produced product is removed from the mold after cooling completely. At this stage, the final plastic piece resulting from the injection is formed with high precision.
Applications of plastic injection
Plastic injection provides the possibility of mass production of plastic products with good quality and reasonable price. Today, plastic injection has wide applications in various industries, below we mention some of the applications of plastic injection:
Automotive: Plastic injection is widely used in the automotive industry to produce the main and spare parts of the car, such as interior decorations, bumpers, dashboards, fenders, lights, handles, engine-related parts, etc. . Electronics: Injected parts play a vital role in the electronics industry, for example the production of mobile phones, laptops, game consoles and other electronic devices all have plastic parts that are produced using the plastic injection process.< /p>
Medical equipment: The medical industry relies on the plastic injection process to produce various devices and components of medical and laboratory equipment such as syringes, sampling containers, surgical instruments, respiratory equipment, implants or implantable devices, etc. . Consumer goods: The plastic injection process is used to produce a wide range of consumer goods, such as a variety of household appliances, toys, tableware and kitchenware. Packaging: The packaging industry uses the plastic injection process to produce all kinds of containers, lids, lids and packaging components for food, chemicals, cosmetics, health and medicine.
Equipment Required Plastic Injection
In the plastic injection process, using the right tools and equipment will have a direct impact on business success and profitability. Some of the equipment needed to enter the plastic injection profession are:
Plastic Injection Machine
Plastic injection machine is the most important machine used in plastic injection. This device is responsible for processing and injecting materials into the mold.
Plastic injection mold
Plastic injection mold is a device that is usually made of steel and is customized based on the geometrical and dimensional specifications of the part in question.
Plastic Injection Accessories
Generally, to produce a part using the plastic injection process, various accessories and accessories such as chiller, automatic material conveyor, mixer, mill, overhead crane, robot, mold temperature controller, hot runner controller and material gasifier are used. takes Although the use of these equipments is not necessary in many cases, their use will have a significant impact on increasing efficiency and reducing production costs.
The plastic injection process has a bright perspective in the field of production with its productivity, adaptability and unique developments. Today, after more than a century since the emergence of this technology, plastic injection has reached its maturity and has opened its place as the most widely used manufacturing and production process in the plastic industry.
