Home > Universal Screw >> Injection Screw Barrel

Process Specifications of screw and barrel:
25-38000KN clamping force
30g-50000g injection unit

Types of screw:
[For good plasticizing effect,we have different design of screw barrel to meet customer’s demand]
Gradual type,mutant type,wave type,barrier type,double screen type,shunt type,separation type,exhaust type,pin type,mixed type,double- head type,three-head type,multi head type etc.

The material of Screw:
1.Material:38CrMoALA
Nitrided treatment,Surface hardness:HV≥900
Nitrided Depth:0.5~0.8mm
2. Material:special alloy steel
After vacuum hardening heat treatment process,can greatly improve the service life of the three small pieces.
3.Material:the surface tungsten carbide ultra-sound overall spray to improve the wearresistance of the screw.
