What is plastic injection?
Plastic injection is the process of melting plastic raw materials and injecting them into a mold. This process is widely used to mold plastic materials into desired shapes and to enable mass production of various plastic products.
Plastic injection process is performed with automatic or semi-automatic injection machines. The process usually consists of the following steps:
- Plastic material preparation: Plastic granules or powders are put into the hopper or hopper in the injection machine. These materials will be used for heating and melting.
- Material melting: Plastic materials are heated and melted by a screw (or propeller) in the cylinder. This molten plastic becomes ready to be injected into the mold.
- Injection process: The prepared molten plastic is injected into the mold under high pressure with an injection plunger or screw. This process allows the plastic material to completely fill the cavity inside the mold.
- Cooling and hardening: The injected plastic is left to cool in the mold. When the plastic cools down, it hardens and takes the desired shape.
- Removal of the part: The plastic product that has hardened in the mold is removed from the mold and cleaned. Then it becomes ready for use.
Plastic injection enables mass and precise production of plastic products. With this method, various plastic products such as toys, household appliances, automotive parts, medical devices, packaging materials can be produced. Therefore, the injection molding method is an important technology that is widely used in the modern manufacturing industry.
