Advantage of Hegu WPC extruder
WPC extruder
Special designed high quality WPC extruder
1, The gearbox is from Guomao brand which is top brand in China, its advantage is low noise, stably performance, long using life, big power. our Romania customer used this gearbox for 8 years already and still working good.
2, the special designed double screw hopper is good using for WPC material which with uniform material, with double screw rotating, the powder or granules or flakes in WPC material can be uniform feeded to the extruder.
3, High quality motor, we supply Siemens motor or Hongqi motor, both are top brand in China, our customer used our Hongqi motor for 8 years already and it still working good.
4, our extruder structure is made by casting iron which is very strong, it is very important to reduce the machine shaking in running condition, so the strong structure can give long using life and also stably production
Special designed WPC screw with Bimetallic material
The WPC material with high wood percentage may easy damage the screw of WPC extruder because of big friction in the machine working. Our WPC screw is specially designed and made for WPC material.


Bimetallic Material: Tungsten Carbide alloy

Hardness After Hardening&TemperingHB280-320

Nitrided HardnessHRC55~58

Nitrided Case Depth0.45mm-0.7mm

Nitrided BrittlenessLess than Grade 2

Surface RoughnessRa0.4um

Screw Straightness0.015mm

Bimetallic HardnessHRC65

Bimetallic Depth: 2.5 mm

WPC screw
WPC barrel
Special designed WPC barrel with SKD coating
Our barrel for WPC extruder is specially made with SKD coating, according to different material, we have half SKD coating design and full SKD coating design.
the SKD material is used for increasing the wearing resistance of the barrel to against the big frication in the WPC extrusion.
if the Barrel has been damaged by the frication in WPC extrusion, then the gap between screw and barrel shall be bigger and bigger, and the screw rotating maybe get problem because of the gap, and finally the screw will be also be damaged.
so it is very important to get strong barrel to increasing the using life for both screw and barrel.
the SKD coating barrel shall increase the using life to be 1.5-2 times comparing with the normal barrel.
Top quality electricity control cabinet
Our electricity control system is special designed according to our 22 years manufacturing experience
1, Top quality components: ABB inverter, Siemens contractor, Omron temperature control, Siemens PLC control
2, Humanization design: the cabinet design is humanized for engineer operation, all the cables has well placed in order and with detailed marks, all the doors with visual glass, all sides of cabinet with cooling blowers.
3, turntable operation panel: the operation panel is designed with turntable arm near to the die where engineer will standing when operation the machine
4, one cable electric supply: for supplying electricity to the whole line, customer only need to use one main cable to connect with the cabinet power switch, and the cabinet will supply the electricity to all the auxiliary devices in the wpc extrusion line
5, customized design: we also can design the electricity control system according to customer's requirements.
