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: |

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:
