Plastic molding machines, also known as injection molding machine, is a machine that is used to mold and shape plastic parts. The process of plastic molding begins by feeding plastic pellets or granules into the machine's hopper. The pellets are then heated and melted and then 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.

Plastic molding 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 can be used in many industries such as automotive, consumer goods, healthcare, packaging, and electronics.

The plastic molding 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 melted. The screw is responsible for moving the plastic forward and exercising the necessary pressure for injection. The nozzle injects the melted plastic into the mold, and the mold is used to shape the plastic.

Injection molding is a versatile and efficient method of mass-producing plastic parts with a high degree of accuracy, and it is one of the most widely used methods of plastic molding.
