Platit AG is a Swiss company that manufactures and markets coating equipment for the manufacturing cutting tool industry. It is one of the technology leaders in Physical vapor deposition coating technology .
PVD coatings are typically applied to cutting tools – such as drills, hobs or endmills -, molds and dies, and machine components to extend their lifetime. Typical PVD coatings include Titanium nitride (TiN), TiCN, or TiAlN ,AlCrN, Nanocomposites, TripleCoatings3, and QuadCoatings4.
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 a wide variance of coating structures.
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.But Platit produces big dedicated coating units also, e.g. for long broaches.
