Bimetallic screw and barrel Base material of bimetaillc barrel: 45# 40Cr Bimetallic type: centrifugal casting Application: for injection molding machine and extruder Products range: 12000mm Nitrided layer thickness: 0.50-0.80mm Hardness: HV960 Strightness: 0.015mm/m Chrome coated layer: 0.02-0.085mm Suitable plastic material: PP,PE,ABS,AS,PS etc. Material: SACM645,SCM440,38CrMoAlA For our bimetallic screw,we have adopted advanced technique (HP/HVOF) of surface harding process by the whole screw surface, WPT1 alloy with corrosion resistant suits for nylon,PVC, PC,PMMA and so on. WPT2 alloy with corrosion resistant and high temperature resitant suits for magnetic powder,magnesium and alumium powder,bakelite injection and so on. WPT3 is compatible with WPT1 and WPT2. For our bimetallic screw, we have adopted a new technology of surface hardening process by the whole screw surface instead of only hard facing the screw flights by PTA treatment. For bimetallic barrel, we have raised its tungsten carbide content to 25%, 40% and 60% from the previous 10% of tungsten carbide and increased the processing length to 10000 mm from the previous length of 4000mm.
