Screw

Essential component of the injection unit. Its main function is to contain, melt, and homogenize the material, as well as dose the amount of plastic to be injected into the mold.

Internal diameter of the barrel where the plastic will be melted and mixed before being injected. An optimal diameter allows for precise control of injection speed and pressure.

Device used to allow unidirectional flow of fluid and prevent backflow, placed on the screw.

Unit responsible for melting plastic material and injecting it into the mold. It consists of a cylinder, injection screw, and nozzle.

Stage of the molding process where the screw operates through rotational speed and back pressure to achieve the desired shot size and homogenization of the molten plastic.
