XPS Bimetallic Extruder Barrel for Plastic Machinery Parts

Hardness After Hardening & Tempering HB280-320 Nitrided Depth HV850-1000 Surface Roughness Ra0.4 Chrome Hardness ≥ 50HV Chrome Thickness 0.025~0.1mm Alloy Depth 0.8~2.0mm Our company has not only got the remarkable achievement on the production of normal bimetallic screw and barrel,also we have deeply researched on the barrel and screw for the special engineering plastic,for now much of engineering plastics add the calcium,kaolin,red clay, silica or add Glass fiber, carbon fiber, boron fiber and halogen free plastic to make the original plastic much better to adapt the specific plastic products.On the other hand, it may make the screw and barrel wear and corrosion quickly, In order to solve this problem,we have invented a kind of special alloy powder,whose ingredient contains 25%~50% Wc tungsten carbide.It makes the service life of screw and barrel much more longer than the other kind…
