New automotive casting objectives highlight the deficiencies in standard tooling materials, but an alternative promises quality, lower cost, longer tool life, and more
Excerpt from the Foundry Management & Technology November 2019 article
The difficulties of casting high-volume automotive parts are well established, and those issues become more critical in production of critically engineered parts, such as the increasing volume of parts produced by high-pressure die casting (HPDC.) Three experts in hot-work production addressed the issues recently in a white paper for Uddeholm AB's newly developed Uddeholm Dievar 25 Joules tool steel for die manufacturing. It gives "the perfect balance between toughness and heat-checking" for HPDC, and other applications, they claim.
Most dies used by foundries, diecasters, and OEMs are formed in AISI H13 or H11, but the Uddeholm experts raise the concern that the die-related problems of HPDC powertrain and transmission castings have not changed in decades, and may be more acute with the advent of production for hybrid and electric vehicle castings.Read More
