According to different material and plastic products to design
different screw structure ,compress rate and L/D!Â
According to different material and plastic products to design
different Barrel with exhaust system and IKV force load system!
As per customers’ demand,we can supply below:
PVC/PE Film Blowing Screw; Blow Molding Screw; PS/PE/PP/ABS Sheet
Extrusion Screw; PE Aluminum Plate;PPR Pipe Screw;EVA
Extrusion Screw;HDPE High efficiency Screw;PET Straps
Screw;XPS/EPE Foamed Screw;Granulation Screw,Vented single
screw etc!
Bimetallic Screw and Cylinder:
Bimetallic Screw production method:
Plasma Alloy Coating Spraying or Wc/Co Whole spray
welding
Bimetallic Barrel production method:Centrifugal Casting
(Inlay Alloy)
The PTA powder plasma welding applies the positive and negative
electrodes of arc welding, allowing the welding path to be
completely,welded with the base material.The minimum possibility of
the welding path becoming less rigid fully prevents the welding
layer from peeling
off – thereby effectively upgrading the life time of the
screws.
Outstanding Features
of Bimetallic Screw and Barrel:
Hardness HRC****5 Â
 Outstanding
corrosion-resistance.
Hardness layer reaches 1.5 m/m
thickness.Hardness does not decrease with depth.
Hardness does not decrease under normal
temperature.
Abrsion resistance / wear resistance on the
hardened layer is 2~3 times higher than that treated by
conventional heat treatment.

Inspection
As the
screw and barrel are the important parts for plastic extruders and
injection molding machine,they affect the machine performance
and quality directly,therefore,SHEEN established quality
control system strictly as ISO ***1:***8 International Quality
System, our every production process is under strict
inspection , Those provides solid foundation for our
quality products!What we need to do is to make sure best
quality of each screw and barrel,Till now,our screw and barrel
has been sold to more than *0 countries in the world and enjoy a
good reputation by our customers!
My
