voestalpine eifeler Coating
With the acquisition of eifeler by the voestalpine AG, we are one of the leading suppliers of PVD coatings. Since 1983, we have not only been engaged in coating of surfaces, but also continuously set new standards in research and development. It’s therefore no surprise, that today eifeler technology is synonymous with high-tech and premium products.
Why PVD Coating?
PVD coatings (Physical Vapor Deposition) have been established for years in almost all markets and industries to improve the durability and performance of tools and components of all kinds.
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)
