Advanced Coating Technologies (ACT) offers more than 30 types of physical vapor deposition (PVD) coatings for die and injection molds, and also can create custom coatings for more specialized requirements. The coatings are formulated to provide corrosion- and wear-resistance, as well as a lower coefficient of friction to die mold parts for easier release.  PVD coatings also are said to extend the life of parts; facilitate easy demolding; reduce residues and the need for polishing; and increase fluidity of forming materials to improve forming performance.

PVD coatings also are said to extend the life of injection molds by reducing wear from abrasive melts, and to allow shorter cycle times, reducing unit costs and increasing productivity. In addition, the coatings reduce “sticking” force, eliminating the need for release agents while making the mold easier to clean, the company says.  The coatings also improve injection pressure, melt flow and mold filling, which reduces sink marks and other surface flaws, ACT adds.
