Advantages of double alloy barrel screwAdvantages of double alloy barrel screw
The double alloy barrel screw is a layer of 1-2mm wear-resistant, corrosion-resistant, high-temperature resistant alloy spray-welded on the inner wall of the barrel. Its effective service life is greatly improved compared with ordinary nitride barrels. It is a high formula for processing PVC calcium powder. , Increase the wear life, the superiority of bimetal is particularly obvious.
Bi-alloy barrel screw processing technology:
Using high-speed ion spray spray welding dual alloy process.
Advantages of double alloy barrel screw:
Double alloy barrel screw is composed of a common metal material with certain mechanical strength as the base material, and a tube with a special alloy material protective layer compounded on the inner hole working surface. This layer of alloy protective layer with a certain thickness and a certain hardness depends on the conditions of its use, or it has abrasion resistance, corrosion resistance, or both abrasion resistance and corrosion resistance. This layer of protection It is evenly attached to the base material and interlocks with the base material in the metallography without falling off, forming a solid whole.
Application of double alloy barrel screw:
Double alloy barrel screw is suitable for all kinds of special engineering plastics such as glass fiber, plastic and PPA, PPO, PPS, LCP, magnetic powder, PC and so on.
