Stamping mold is a widely used cold working mold in the metal processing industry, mainly used for blanking, bending, stretching and forming of metal sheets. Different from hot casting and extrusion molds, stamping molds work at room temperature, facing high-frequency friction and impact loads, so mold steel hardness, wear resistance and impact resistance are the core selection indicators. At present, domestic stamping mold materials are divided into cold work steel, hot work steel and high-speed steel, with different applicable working conditions.
Cr12MoV cold work steel is the most widely used stamping mold material, with hardness up to 60–62HRC after heat treatment. It has excellent anti-wear and anti-deformation ability, suitable for high-frequency stamping of stainless steel, iron sheet and aluminum sheet. For ultra-precision thin-sheet stamping, SKD11 steel is selected, with higher dimensional stability and 15% longer service life than Cr12MoV steel.
The biggest mistake in stamping mold material selection is confusing cold and hot work steel types. Many manufacturers use H13 hot work steel for cold stamping to save costs, but H13 steel has low cold hardness, which is prone to edge collapse and deformation after 10000 stamping times, resulting in frequent mold replacement. Industry data shows this wrong selection causes 68% of early mold failures.
Process treatment directly affects stamping mold performance. Heat treatment quenching and tempering processes determine mold hardness and toughness matching. Unreasonable heat treatment will lead to excessive mold hardness and insufficient toughness, causing cracking in stamping process. Precision grinding and surface polishing can eliminate mold edge burrs, ensuring smooth stamping and avoiding sheet scratching defects.
Xinfeng Machinery focuses on customized production of various stamping molds, selecting targeted mold steel materials according to customer stamping materials, thickness and production frequency. All molds undergo strict heat treatment and precision finishing, adapting to high-frequency and high-precision stamping working conditions. Standardized production processes ensure stable mold performance and long service life, helping enterprises reduce mold replacement costs.
