PVD Coating Solution Provider - voestalpine HPM India

PVD Coating Solution

We offer customers with tailored PVD coating solution where hardness, corrosion resistance, high temperature resistance and tri biological properties can be modified to resist different surface failures.

Our state-of-the-art coating center is equipped with the latest PVD coating process technology.

Why PVD Coating?

PVD coating is a vacuum coating technique, in which a film is created to maintain a harder surface on the target material. This film extends the life of the tool, lowers tool maintenance and improves overall part quality. The environment that may otherwise be able to perform in.

An irreplaceable quality of PVD coatings is that it uses lower temperatures for the application process avoiding the disadvantages of procedures such as CVD coating, in which the tool has to go through the process of becoming soft post-coating, and then re-hardened again – putting it at risk of becoming distorted.

Our Capability:

Our PVD Coating Center specializes in creating custom coatings for the automotive, firearm, die casting and plastic injection tooling industries. We are equipped to accommodate a wide variety of customer needs. The coating center operates alongside the company’s steel divisions. Offering an unparalleled level of service compared to any special steel company worldwide.

Our coating center is equipped with:

»Alpha 900 (Ø 750×880)
»Alpha 400 (Ø 450×485)

We are specialized in ultrafine coating and have 7 stage cleaning line
