1. Select the tungsten steel material and size to make the screws or nuts mold correct.

2.According to the difference of the forming difficulty,size,length of screws and nuts,the die structure should be designed reasonably,multi-station and nut mold should be allocated on a reasonable basis of the upsetting deformation and forming times.

3.The mold has fine craftsmanship,accurate size,bore diameter to match the mirror finishing requirements.

4.Interference voltage distribution margin,choose the appropriate alloy taper size.

5.Shell steel sleeve must be rigid and well heated,and the hardness range after the vacuum heat treatment should be between 45℃-48℃.

6.Keep the die bore and wire surface clean and smooth, the cold drawn wire must be nailed firmly after ball annealing.

7.We use diamond wheel to grind the cycle and the end of tungsten.

The world’s leading tool steel supplier continues to supply high quality materials.

We have developed our own optimum heat treatment cycle to ensure consistent hardness and toughness according to customer applications.

1. The master worker have the experience of mold and structural design , analyzing the reason of  the unreasonable distribution of die stress ratio and deformation.

2.The cleanliness of the mold, the inner hole finish is not enough.

3.The rigidity of shell sleeve material, the heat resistance,and the heat treatment hardness are unreasonable.

4.In order to save the cost of production, they selected poor quality tungsten carbide steel and wire rod, alloy specifications and steal material nailing serious wheels are unreasonable.

5.The collider is not appropriate, without replacing lubricants and checking machine long-term.

6.The master worker of adjusting must have high technical level.

We have very strict quality control procedures.

Each part has been carefully processed (by grinding, machining, milling, wire-cutting, EDM etc),

with exact tolerances shown on the drawing,and every dimension of every part has been carefully checked both  in the production line and QC check before packing and shipping.

In this way, we assured the high precision ,so as to have good interchangeability between the tools in customer’s factory.
