Bimetallic Screw for Plastic Machines


The Plasma welding arc is ionized by ionization to generate a high-temperature ion gas stream, which is ejected from the pores of the nozzle and compressed to form a slender arc column. The temperature is reachable, higher than the conventional free arc, such as: argon arc welding only up to 5000- 8000K. Because the plasma arc has the characteristics of slender arch and high energy density, it has a wide range of applications in the field of welding.

PTA is a Nickel-based alloy. Its chemical composition includes Ni,WC,CO,Fe,Si,B,Cr and C.

Application Area

Applications in Plastic Machinery



Abrasion resistance / wear resistance on the hardened layer is 2~3 times higher than that treated by conventional heat treatment.
