BimetallicScrew production method:

PlasmaAlloy Coating Spraying or Wc/Co Whole spray welding

BimetallicBarrel production method:Centrifugal Casting (Inlay Alloy)

The PTApowder plasma welding applies the positive and negative electrodes of arcwelding, allowing the welding path to be completely,welded with the basematerial.The minimum possibility of the welding path becoming less rigid fullyprevents the welding layer from peeling
off – therebyeffectively upgrading the life time of the screws.

OutstandingFeatures of Bimetallic Screw and Barrel:
Hardness HRC50-65 Outstandingcorrosion-resistance.
Hardness layer reaches 1.5 m/m thickness.Hardness doesnot decrease with depth.
Hardness does not decrease under normaltemperature.
Abrsion resistance / wear resistance on the hardened layer is2~3 times higher than that treated by conventional heat treatment.
