💡 What is Plastic Injection Molding?
Plastic injection molding is a widely used manufacturing process in the plastics industry. It involves melting plastic into a liquid state, injecting it into a mold, and allowing it to cool and solidify into the desired shape. This method can handle a variety of plastic materials and is ideal for mass production.

🏭 How Does Plastic Injection Molding Work?
The injection molding process involves four main steps:

1. Preparing and Melting Raw Material
- Plastic resin in pellet form is loaded into the injection molding machine.
- The heating system melts the plastic into a highly viscous liquid.
- The molten plastic is then moved towards the injection nozzle for molding.

2. Injecting Plastic into the Mold
- Molten plastic is injected into a mold under high pressure.
- The mold contains cavities in the shape of the final product.

3. Cooling and Solidifying
- Plastic cools and solidifies inside the mold.
- Cooling systems speed up this process, increasing production efficiency.

4. Ejecting the Molded Part
- Once the plastic has fully solidified, an ejector mechanism pushes the finished product out of the mold.
- Additional finishing processes like trimming or polishing might be necessary before final use.
