voestalpine eifeler Coatings provides state-of-the-art, Physical Vapor Deposition (PVD) coatings for Die Casting. eifeler’s patented, two-stage process includes an initial hardening of the surface via Plasma/Ion Nitriding, followed by the application of a mono-layered PVD coating. Referred to as Duplex-TIGRAL®, this treatment creates a hard, wear resistant barrier that reduces or eliminates the effects of soldering, erosion and wear of the tool steel surface.
By applying a PVD/DLC coating, tool life can be increased. This improves production length, reliability and part quality as well as reduces downtime and maintenance costs. By combining a coating with the most suitable tool steel, correctly machined and heat treated, even greater benefits and savings can be achieved. Through our close cooperation with tool makers, material suppliers and our additive manufacturing providers, eifeler is uniquely positioned to support you throughout the process and increase your total tooling performance.
In die casting, melts of different alloys are injected with pressure into a die set and then solidified. Depending on the melt alloy, the dies are subjected to different high thermal and mechanical stresses.
Typical die failures
Die casting dies are exposed to severe thermal and mechanical cyclic loading, which puts high demands on the die material. Thus, there are some phenomena, which restrict die life.
Die material properties
For the best die performance, the following basic die steel values and properties should be high and good:
