Processing:
Titanium plating on the surface of tungsten steel punches is an extremely valuable process treatment. The process typically involves advanced physical vapor deposition (PVD) or chemical vapor deposition (CVD) techniques. In PVD, titanium atoms are uniformly deposited on the surface of a tungsten steel punch by evaporation, sputtering, etc., using a vacuum environment to form a tightly adhered titanium coating, while CVD involves a gaseous reactant that chemically reacts with the surface of the punch to grow a titanium layer.
Application:
In the field of automobile manufacturing, hexagonal titanium-plated tungsten carbide punches play a vital role. For example, a well-known automobile brand in the production of engine block, the need for the cylinder block connection parts for punching processing. As the cylinder material is mostly high-strength aluminum alloy, ordinary punches are very easy to wear after frequent stamping, and punching accuracy is difficult to ensure.
The problem is solved by the use of hexagonal titanium-plated tungsten carbide punches. With a hardness of 89 - 93 HRA, it can easily penetrate through the aluminum alloy material and accurately complete the punching task. The unique hexagonal shape of the punch ensures that the punch is stable and does not shift at high speeds, guaranteeing the accuracy of the punching position.
Advantages:
Titanium plating offers a number of significant advantages. First of all, excellent corrosion resistance, titanium layer as a solid shield, whether acidic, alkaline or humid working environment, can effectively block the external erosion, to protect the punch substrate, greatly extending the punch life.
