Injection Molding Plastic Extruder Screw machining from China

Precision Machining plastic extruder Screw barrel adapt high quality 38Cromaia raw material and due to different plastic material , screw barrel can spray bimetallic treatment which with more long service life.


The bimetallic treatment of our screw by the PTA machine. It is a advance equipment which has not been broadly used in bimetallic treatment. Compare to the manual process the advantage is better temperature stability, dense structure and uniform thickness and not liable to crack.


Precision Machining plastic extruder Screw barrel is centrifugally cast a 2~4mm thick alloy coat on the output section of barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided barrel. Bimetal has more obvious advantages when processing high calcium carbonate powder PVC mixture to enhance the abrasion life.


Material Application

1) General Plastics

2) ABS,PA,PC,PE,PET,PP,PS,EVA,PU,PVC,U-PVC,etc

3) PA + GF(Glass Fiber)

4) Flame-resistant Reinforced Plastics

5) Modified Engineering Plastics

6) All kinds of Mixed Recycled Material(in Scrap or Granule),etc


What we can do:


-HDPE/LDPE/LLDPE blowing film extruder single screw and barrel:different design to meet client request on production

-PP/PE granulation or recycling screw barrel:New geometry design according experience modify.

-PVC pipe/profile/componds/sheet/foam board:Professional Produce Experiece on both China & Europe extrusion machine.

-HDPE/PPR pipe high capacity single screw barrel:Big L/D design,high speed,high capacity.

-Haitian,ChenHsong brand machine injection screw barrel supplier in China


Application

The screw can be work for PVC UPVC pipe tube extrusion, for sheet film extrusion and for profile extrusion.

The screw barrel will design according to customer demand like raw material, final product and output.


plastic injection screw dapt high quality 38Cromaia raw material and due to different plastic material , screw barrel can spray bimetallic treatment which with more long service life.
