Experiences with the application of the NADCA standard in the hardening shop
The lifetime increasing of dies for die casting is significantly affected by the appropriate choice of material, the correct heat treatment and applied control mechanisms described by NADCA standard, the latest revision 2016. The die casting dies producers these control mechanisms very often neglect and so the initial condition and quality of the material is a secret. The questions about the quality of the material and heat treatment are placed when the problem is discovered, e.g. the surface failures on the dies or insufficient lifetime. The paper presents many years of experience with the testing of die casting materials and the results of these control processes for the most commonly used steels.
