Jul 19, 2018

When product profile, we always choose the meshing type counter-rotating conical screw or the cylindrical screw extruder, and the meshing type co-rotating twin-screw extruder can also be used.

The meshing type counter-rotating twin-screw extruder is always used for product profiles, it has strong plasticizing and shearing action on the raw materials, and the raw materials are plasticized, melted and kneaded uniformly, and are more suitable for extrusion PVC materials.

For the mixing of raw materials, the granulation of the raw materials after mixing and plasticizing, the meshing type high-speed co-rotating twin-screw is generally used in the twin screws extruder, screw elements may be two or three heads.
