The molds used in the food and packaging industry need to have both superior surface properties and long lifetime, as well as needing to be healthy, safe and hygienic. Furthermore, the coated parts are expected to be, to a certain extent, resistant to corrosion in water and moisture media.

Since PVD coatings have a chemically inert ceramic structure, high biocompatibility and advanced mechanical properties, this provides an ideal combination of intended properties. It provides extremely safe and hygienically long mold life, especially in plastic cover molds made of copper alloys and tool steels, plastic spray nozzles, can-box forming molds, in the injection molds of various plastic products that come into contact with foodstuffs and medicine tablet press molds.
