What should do if carbide die is always strained? 3 ways to get it done!

       Carbide stretching die can be said to be often seen, but it takes a while to design this type of mold. After all, there may be some differences between the on-site mold trial and the mold design.

The most common problem in tensile die test is strain. So how can we prevent strain?

1. Material
Some materials with special requirements need special treatment, such as phosphating, spraying and other methods. This is to produce a film on the surface of the mold to prevent or reduce the problem of strain. This method is the most effective, but one thing is more expensive, so this method is not used much.

2. Material structure
The cost of using a protective film on the surface of the product is very high, so we use plastic film instead, and it is a good way to get a layer of PVC film. Some small products can be solved with lubricating oil.

However, this method of making film is only suitable for large products and small batch production, because each product has to be made of film, which adds a lot of time and waste.

3, mold structure

When talking about this, the editor cannot help but say that the previous methods can be said to have not completely solved the problem. The best way is to immediately change the material, hardness, or Titanium plating and polishing of the product.

Make the product material and the contact surface of the concave and convex mold change essentially to eliminate the problem of strain. This is the best and most cost-effective way
