110/220 conical extrusion twin screw for spc flooring conical twin
screw and barrel for pvc extrusion
The taper twin barrel screw is a design that combines a conical and
twin screw to provide a more uniform temperature distribution and
improve the melting and extrusion of plastics. The application of
the cone twin barrel screw has achieved remarkable results in the
plastic machinery manufacturing industry. It not only improves the
quality of plastics, but also greatly improves production
efficiency. By optimizing the extrusion process, the cone twin
barrel screw can significantly reduce energy consumption and scrap
rates. It suitable for pvc ,pe,pp pipe ,profile,panel, wpc,foam
board,and granulation and other products.
