Bimetallic single screw barrel for haitian injection machine Specification

Screw diameter:Φ20mm-Φ220mm
Mould clamping force:25-38000KN Injection capacity:30-50000g

Screw can be designed ccording to different plastic material and nozzle!

( wear-resistance corrosion- resistance, high temperature resistance, high pressure resistance)

As per customers’ demand,we can supply below:
1:PMMA Screw,Bakelite Screw,PVC Screw,PA Nylon+GF Screw,PC Screw
2:All kinds of accessories, a plastic head, apron, shoot flange nuts,nozzles,end caps.pistons etc

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 HRC50-65 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.
