Common material grades of cold extrusion die steel
Cold extrusion die steel (metal)
Choosing the correct mold steel for your application depends primarily on the type of material being processed, its strength, thickness and the geometry of the workpiece. The most important failure mechanisms are adhesive wear, roughening, cracking, abrasive wear and plastic deformation. During the cold extrusion process, the punch applies pressure to the metal blank, causing it to move in a specified direction under control.
Cold work mold failure mechanism
Due to cyclic mechanical loading, sliding contact between the processing material and the mold surface, the mold surface is gradually damaged. These wear will affect the quality of the formed workpiece (causing excessive tolerances or surface quality problems), and the mold will have to be replaced (complete failure), reground, or refurbished.
This maintenance process means production is stopped and production efficiency is reduced. Therefore, choosing mold materials that can resist various types of corresponding failures is crucial to improving productivity and economic benefits. Choosing the right tool and die steel is closely related to avoiding tool failure in practical applications.
