Conical Twin Screw For PVC Pipe,Profile,Sheet,Wood,Granules And Wpc

Short Description:

The conical twin-screw is mainly used for processing products such as pipes, profiles, sheets, and wood-plastic composites. It adopts a low-shear screw design, which can reduce the risk of material thermal decomposition. The twin-screw is divided into conveying, shearing, dispersion, and mixing sections. The material passes through the screws to undergo physical modification and mixing, featuring efficient plasticization and uniform mixing.
