Product Description

Specifications:

Bimetallic Screw barrel:

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.
