Bimetallic Screw for Plastic Machines
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.
PTA is a Nickel-based alloy. Its chemical composition includes Ni,WC,CO,Fe,Si,B,Cr and C.
Applications in Plastic Machinery
Abrasion resistance / wear resistance on the hardened layer is 2~3 times higher than that treated by conventional heat treatment.
