Single screw extruders especially used for polyolefine material possess effective plasticizing effect and high extrusion speed. The special detachment type mixing screw and the standard designed die with spiral structure&reasonable channel are applicable to produce pipes with smooth inside and outside face.

Unique sizing and cooling mode is capable of producing pipe scope 50- 200mm, production speed is up to 0.6-1.5M/minAll kind of polyolefine materal, multi-layers spiral strengthening pipe can be co-extruded for various uses, 80% of trcycle material can beused in production; Optimum spiral copper sizing sleeve, its entrance carrying pre-cooling And powerful vacuum device to suit for high speed extruding pipe; Specific design for spray cooling trough; Cooling water trough is made of stainless steel; High efficient cooling comes from peculiar spraying nozzle and high efficiency water pump; Three-dimensional regulation, longitudinal move by motor; Advanced co-extrusion technology and low cost to use recovery material.
