1.Single Screw Extruder:

Single screw extruder PVC plastic extruder for PVC pipe making.
The conical twin screw extruder PVC plastic extruder for PVC pipe making is developed for high output of twin-pipe/four pipes extrusion. The main machine is SJSZ51/105 or SJSZ65/132 conical double-screw extruder, is equipped with double-tube single-control stainless steel spraying shaper to form a production line. It avoids a waste condition when one tube is adjusted and the other one is affected. The auto single-control double drawing machine and cutting are combined with the front shaping technology to make operation more flexible. Let you enjoy economic benefit which is brought about by separately control double-tube extruding. The diameter of the extruded pipe is from Φ16-Φ63(mm). It can fully use the extruding capacity of the extruder.

5.This pvc pipe vacuum  foaming tank   is composed of conical twin-screw extruder,vacuum calibration tank,haul-off ,cutter and stake etc. 

claws Haul-off 
Multi-claw Haul off Machine
Double/Belt Tractor, mainly matched with plastic extruder, used for traction of various materials such as plastic PVC/PE/PPR pipes, engineering materials PEEK/PA/PC Bars, Profiles, Hoses, etc., With a wide range of applications,Easy to use.
Three claws, four claws, and six claws, using multiple crawlers to pull at the same time, SCR stepless speed regulation or frequency conversion speed regulation, mainly used in conjunction with plastic extruders, used for various medium and large diameter plastic pipe rods Extrusion traction of materials.
It has the characteristics of large traction force, uniform traction force distribution, the pipe is not easily deformed, and the function of thickening the pipe wall. It is the most ideal traction method for plastic pipes. And also equipped with an automatic length meter to control the subsequent cutting.
