Injection molding is a fascinating process used in the manufacturing of plastic parts, from small components to large panels. It involves melting plastic pellets, injecting the molten plastic into a mold, cooling it to solidify into the desired shape, and finally ejecting the finished part.

Injection molding produces plastic parts through a straightforward approach. Plastic pellets feed into a heated barrel to melt. The liquid plastic then injects at high pressure into a mold. After cooling, the solid part ejects. This high-volume manufacturing method repeatedly produces intricate, affordable plastic components.

Plastic injection molding is a manufacturing process that involves injecting molten plastic material into a mold cavity. The molten plastic is then allowed to cool and solidify, forming the desired shape. The process involves four main stages, namely clamping, injection, cooling, and ejection.

The injection molding process will essentially heat plastic material to its melting point, and the injection unit will force it into a created mold. Once in the mold, the part or product will harden as it cools, and the solid product will be ejected.

Plastic pellets are fed into the injection molding machine by the hopper. The barrel of the machine is heated and the pressure from the machine melts the plastic pellets. The molten plastic injected into the injection molding machine is called a “shot”. The molded parts are formed by the heat and pressure of the machine.
