Plastic injection machines, also known as injection molding machine, is a machine that is used to mold and shape plastic parts. The process of injection molding begins by feeding plastic pellets into the machine's hopper. The pellets are then heated until they become molten and are injected under high pressure into a mold. The mold is usually made of metal and is clamped shut while the plastic is injected. Once the plastic has cooled and hardened, the mold is opened and the finished part is ejected.

The plastic injection machine consists of several main components, including the hopper, barrel, screw, nozzle, and mold. The hopper is used to feed the plastic pellets into the machine, while the barrel is where the plastic is heated and mixed. The screw is responsible for moving the plastic forward and exercising the necessary pressure for injection. The nozzle injects the molten plastic into the mold, and the mold is used to shape the plastic.

Plastic injection machines come in different sizes, from small, bench-top models to large, industrial-scale machines. They can be used to produce a wide range of plastic parts, from small components to large, complex parts. They are widely used in Various industries such as automotive, consumer goods, healthcare, packaging, and electronics.

Injection molding is one of the most common and efficient methods to mass-produce plastic parts.
