Screw:
1.Diameter: Φ15- Φ400mm
Max Length: upto10000mm
2.Raw material: 38CrMoAlA
Nitriding surface hardness: HV≥900
Nitriding depth: 0.6-0.8mm
In order to get good plasticize different plastic material, we will need different screw designs.
Types: Gradually taper flights, Mutant taper flights, Wave flights, barrier screw, double barrier screw, BM screw, shunt screw, vent screw, pins screw, complex screw and so on.
