Coatings

BÖHLER Mexico is home to a state-of-the-art Physical Vapour Deposition (PVD) coatings centre, equipped with the latest in PVD coating process technology. PVD is a vacuum coating technique, which creates a film on the surface of the required material to maintain its hardness. The film improves part quality, creates higher productivity, and increases tool life. A major benefit of PVD coating is its use of low temperature during the procedure, which avoids distortions in the tool.

BÖHLER’S PVD coatings centre specializes in creating custom coatings for the automotive, die casting, firearm and plastic injection tooling industries, but is committed to accommodate a wide range of customer needs.

The coating centre works side by side with the BÖHLER steel division and thermal processing division to offer our customers a complete solution – we are able to advise on an application with material selection, heat treatment specifications and coating technology.

At BÖHLER, we are devoted to providing on-time delivery, competitive prices for high performance coatings and exceptional customer service.

TIGRAL coating is designed for tools in need of very high resistance against oxidation and abrasion. It is a two stage coating process, composed of a Plasma Nitride and followed by a mono layered matrix coating. This mono-layered matrix composition creates a very ductile film ideal for abrasive environments such as die casting and hot forging. TIGRAL coating avoids the drawbacks associated with high temperature coatings, but easily matches their performance levels. The low temperature application process allows for the metallurgical characteristics of the steel to be maintained. The unique chemistry of TIGRAL offers protection from materials that corrosively attack the tool steel, which results in reduced adhesive wear and alloying between work and tool materials, enhancing part release and greater productivity.

VARIANTIC coating is a high performance coating consisting of a specially designed plasma-nitriding process combined with a low temperature nano-layered PVD coating. This nano-layered feature greatly reduces stress and improves ductility, which increases coating longevity by preventing microcracks in the film. VARIANTIC coating was developed to avoid the distortions and disadvantages associated with high temperature coating processes such as CVD and TD coating, all while providing equivalent results. This coating allows for tools to be easily stripped and re-coated multiple times to maximize tool life without damage to the substrate. VARIANTIC coating is ideal for high pressure applications where adhesive and abrasive wear of the tool is significantly reduced providing impressive production enhancements.
