Common material grades of powder pressing die steel
powder pressing
Powder pressing is to fill the material to be processed into the mold cavity in the form of powder (not solid metal). After sintering, the resulting green body is resized or pressed again to increase accuracy or improve its performance. The powder pressing process is critical to mold life. By choosing SDWST steel for powder pressing, the service life of the mold can be more than twice that of conventional mold steel or high-speed steel molds.
The main considerations in selecting appropriate mold materials include powder type, green compact density requirements, and component shape. It is also important to identify the main failure modes during the pressing process so that the selected mold steel can help solve these problems.
Adhesive nap, adhesive wear and high friction are common issues to consider.
A proven SDWST solution is to use the very powerful PMX4. Other solutions include SDWST's DYCM7 and DYMAX UINPM—two electroslag remelting (ESR) types of cold work tool steels.
Relying on SDWST's high-performance products, you can achieve unimaginable results in powder pressing production - improving quality, shortening production cycle, improving economic efficiency, and meeting all manufacturing requirements at the same time.
