Cold Drawing

1. Through special alloy steel mould cold drawn forming

2. Small deformation

3. Inside and outside surface bright and clean

4. Hardness moderate

5. Suitable for machining

6. Special shape tube necessary procedure

 

 

 

Cold Rolling

1. Through the roller repeatedly rolling the outer surface forming

2. Large deformation

3. Outer surface bright with a mirror effect

4. High hardness

5. Suitable for terminal products

6. High surface requirement tube necessary procedure

 

Combination of Cold Drawing and Cold Rolling

1. High-end products adopt the combination mode of cold drawn and cold rolled.

2. Suitable for subsequent machining

3. Perfect surface

Examples: rifle barrel, shock absorber

 

 

4. Application
