High speed machine screw & barrel & charging barrel Details
1. Abrasion resistant, corrosion resistant.
2. With special treatment, it can effectively increase the abrasion resistance, extend the lifespan.
3.Corrosion resistance,abrasion resistance
4. The heat treatment uses nitriding treatment, chromium plating, high-frequency quenching, wear-resisting bimetallic layer, vacuum hardening and many other methods.
Screw material requirement:
1. The material should be heat resistant, and will not deform under high temperature.
2. The material should be abrasion resistant, and has long lifespan.
3. The material should be corrosion resistant, because the feedings are corrosive.
4. The material should have high strength, can withstand large torque and high-speed rotary.
5. The material should have good machinability.
6. The residual stress and thermal deformation should be small after heat treatment.
