Uses and differences of different types of screw barrel

Diameter and length: The diameter and length of the screw barrel can affect the melting and extrusion effects of plastics. Generally speaking, the larger the diameter, it is suitable for extruding large-sized products; The longer the length, it is suitable for extruding high viscosity plastic materials.

Pitch and Thread Depth: Pitch and thread depth determine the compression ratio and shear force of the screw barrel. For different plastic materials and extrusion processes, it is necessary to select different pitches and thread depths to achieve the best extrusion effect.
