Application

01 Conical Twin Screw and Barrel

1. Nitrided screw and barrel:

Material:	38CrMoAIA
Surface hardness:	≥HV900
Nitriding depth:	0.5-0.8mm
Conical twin screw and barrel types:	φ45/97,φ51/105,φ55/110,φ60/125,φ80/156,φ92/188,φ95/191,φ105/216

2. Bimetallic screw and barrel:
Imported high-strength alloy steel material, the vulnerable parts of the screw are plasma surfacing, the thickness of the shackle base and the Ragi alloy is 1-1.5 mm, and the service life is increased by more than 1.5 times.

3.Conical twin screw and barrel types:

φ45/97,φ51/105,φ55/110,φ60/125,φ80/156,φ92/188,φ95/191,φ105/216

 

The material used for screw and barrel are subject to the demand of customers.
We can design the twin screw and barrel according to the customer's requirement

02 Parallel Twin Screw and Barrel

1. Nitrided screw and barrel:

Material	38CrMoAIA
