Screw and Barrel

technological process

Screw and barrel are the core components of plastic processing machinery like extruders and injection molding machines, which work together to melt, mix, and transport plastic materials. The screw, a helical rod, rotates inside the barrel, a heated cylindrical chamber, to push, compress, and homogenize the material before it's shaped into a product. The design of the screw, including its zones for feeding, compression, and metering, is crucial for controlling the process and the final product quality.
