PVD Coating for Die Casting Die "Amicoat"

The purpose of aluminum die casters is to supply low cost and high quality products. It is necessary to shorten a cycle in production time. Therefore, die lubricant is more strongly sprayed from die surface to solidify a product fast. However, higher cycle die casting is occurred various problems such as heat-checking or soldering on die surface. This reason is that temperature amplitude of die surface is increasing. Amicoat is new multi layer PVD coating which was developed to solve these problems. Amicoat has two kinds of Amicoat-H and Amicoat-D. Amicaot-H suppresses heat-checking and corrosion / erosion more effectively than conventional PVD coatings or nitriding. On the other hand Amicoat-D has excellent soldering resistance. When core pin coated Amicoat-D, the life was improved two or three times compared to conventional PVD coatings.
