Month 10/11/12 Double Ring Date Mark Pin Sets

This double-ring date mark pin set is used in injection mold tooling where molded parts require durable, fast-to-read traceability marks, especially for month/day/indicator layouts. The press-fit mounting helps lock the insert’s position for repeatable impressions across production cycles.

• Date-recycle marking: Suitable for components that must display Month 10/11/12 reliably; the concave character and double-ring structure improve legibility under molding load.
• Packaging and labeling substrates: Common in molds for small housings and caps where molded indicators must remain readable without post-processing; inside arrow paired with the outside ring stabilizes the visual marking.
• Gas-vent / insert neighborhoods: Works in cavity regions that combine venting and marking features; the assembly-style inside arrow + outside ring design supports consistent readouts when multiple features are present.

Select the variant with the required outer diameter D = 6, 8, 10, or 16 mm to ensure clean cavity/core integration and consistent character depth/readability.

Material and heat-treatment details are not provided in the supplied specifications for this MISUMI date mark pin set. As a result, hardness (HRC), wear resistance, and specific thermal treatments (e.g., quench & temper, nitriding) cannot be stated from the available data.

When integrating this type of press-fit date mark insert into a steel mold base, engineers typically choose tool steels based on the trade-off between surface wear resistance (better for high-cycle marking) and core toughness (better for maintaining accuracy around the feature). If your shop standard uses a specific steel grade for date/character pins, align the insert material and treatment with that standard to achieve comparable wear and dimensional stability.

• Verify insert steel grade with the supplier’s drawing before committing to a production run.
• Match treatment level to expected cycle count and molding abrasiveness.
• Confirm final dimensional tolerance after any post-processing (grinding/finishing).

Use the provided dimensional parameters to match the pin set to the mold cavity/core location and to avoid misalignment that could blur the molded concave characters. This product is offered with multiple outer diameter D (mm): 6, 8, 10, 16, while the Month Indication is fixed at 10/11/12 and the Year is fixed at 26.

• Select the correct D to fit your press-fit pocket design. The press-fit method requires the pocket and insert to be designed together (diameter interference/clearance depends on your vendor tolerance standard).
• Confirm feature compatibility: because the marking includes an inside arrow and an outside ring assembly, ensure your pocket shape and surrounding steel thickness provide clearance for the full character profile.
• Match the traceability needs: the variable indication supports Year/Month (Double ring) and Date (Double ring), but the month wording is fixed to 10/11/12 and year is fixed to 26.

If you are designing tooling, request the insert’s drawing-level dimensions and tolerance data to finalize press-fit interference and maintain sharp character impressions.
