Platit AG is a Swiss company that manufactures and markets coating equipment for the cutting tool industry. It is widely regarded as a technology leader in Physical Vapor Deposition (PVD) coating technology. Platit was founded in 1992. The company's headquarters are located in Selzach, Switzerland. Manufacturing plants are located in Switzerland and the Czech Republic. There are 24 sales offices worldwide.

Platit's CEO is Dr. Dominik Blösch. Platit is wholly owned and controlled by BCI Group, a Swiss conglomerate focusing on surface coating and surface treatment for a braoad range of industrial and manufacturing use. Platit is often spelled in all-caps: PLATIT.

"Together, we design and apply high-end coating solutions for functional and aesthetic applications, with a passion for innovation, an entrepreneurial spirit and profound competence."


PVD coatings are typically applied to cutting tools – such as drills or endmills -, molds and dies, and machine components to extend their lifetime. Typical PVD coatings include Titanium nitride (TiN), TiCN, or TiAlN.

Platit manufactures Cathodic arc coating units to deposit PVD coatings. Tools or machine components are loaded into a vacuum chamber, and heated to several hundred degrees Celsius to start a process in which metal from cathodes is evaporated and deposited on the substrates. Typically, cathodes are planar (flat), while Platit's LARC process (LAteral Rotated Cathodes) features cylindrical cathodes that have several advantages over the traditional setup, including the ability to deposit smooth coating surfaces and nanocomposite structures.

Platit introduced the Open Source TripleCoating3® in September 2010. As Platit's customers are generally small- to medium-size companies, their coating units tend to be smaller in chamber size and capacity than competitor's models, which are often aimed for use in larger operations.
