DH2F Steel Date Marked Pins for Die Casting

Date marked pins made from DH2F steel are used in die-casting mold tooling to provide compact, reliable part traceability directly on mold components. They are suited to standard mounting in typical die-casting setups where marking must be durable under repeated cycles.

• Automotive and industrial die-casting molds: the pinned marking supports year/month/day identification so production lots can be correlated to tooling conditions and maintenance history.
• High-throughput repeat-production lines: the DH2F hardened steel variant helps resist wear from frequent insert/removal and handling during die maintenance.
• Small-diameter marking stations: shaft diameters of 6–8 mm enable use in confined die areas while keeping engraving readable.

For engraving, this variant includes ※Designation by WOS, supporting standardized and unambiguous identification across teams and suppliers.

This component is made from DH2F steel, selected for stable performance in die-casting environments where wear resistance and dimensional stability are important. The product description specifies a hardened steel condition, aimed at maintaining the geometry of the date-marking tip during ongoing production.

• Wear resistance: the hardened state improves resistance to abrasion associated with repeated use and mold maintenance.
• Toughness trade-off: as hardness increases, toughness can decrease; DH2F is chosen to balance reliable marking retention with acceptable resistance to chipping under normal tooling conditions.
• Manufacturing process (typical): precision machining of the shaft diameter followed by heat treatment to achieve the hardened condition, then controlled engraving for durable legibility.

No alternative steels, hardness values (HRC), or specific heat-treatment steps (e.g., quench & temper, nitriding) are provided in the supplied data.

Select the pin shaft diameter (D) from the available options: 6, 7, or 8 mm. Choose the corresponding diameter to match the mold’s prepared mounting feature so the pin seats correctly without forcing.

• Diameter matching: align the chosen D with the die component hole/boss size intended for standard mounting in your die-casting layout.
• Engraving format: pick the character arrangement based on your traceability requirement. Options include Year, Month/Day on the top or bottom row, combinations of free designation with Month/Day, or No characters.
• Row capacity: upper engraved character ranges are specified as 1 ～ 31, and the “Month/Day” style upper range is 1 ～ 12; ensure the selected text or date format fits these limits.
• Tolerance/fit: since tolerance values are not provided, verify clearances in your CAD drawings and fixture specs for a stable press-fit or slip-fit as required by your mounting design.
