Year 26 Heat-Resistant Date Mark Pin Outside Rings

This heat-resistant date-marking outside ring is used in modular injection mold tooling where date coding must remain legible under repeated production cycles. It fits service workflows for stamping or insert-based date marking systems, acting as the outside ring only component so operators can swap character hardware without replacing the full pin set.

• Packaging and labeling date coding: In molds producing components that require lot/date traceability, the ring’s WOS-specified character format helps maintain consistency across maintenance intervals.
• Heat-exposed molding lines: For processes where marking surfaces see elevated temperatures, the “heat-resistant” variant supports stable engraving readability during long runs.
• Modular stamping system maintenance: With 1 ~ 12 outer ring characters available, this part supports quick reconfiguration when different cavity/part variants require different date layouts (Year 26).

Because the ring engraving uses ※Designation by WOS and includes a fixed Year (26), it is suited for applications requiring standardized date formats rather than custom character sets.

The provided product data specifies this component as a heat-resistant date mark outside ring with fixed WOS engraving designation, but it does not list the steel grade, hardness (HRC), or heat-treatment process. As a result, no specific metallurgical parameters (e.g., quenched & tempered, nitrided, or carburized state) can be stated from the input.

In general, date-marking insert rings for hot molding environments are selected for thermal stability of the engraving and wear resistance to retain legibility under sliding or stamping contact. When comparing candidate steels for similar functions, engineers typically balance hardness vs. toughness: higher hardness improves wear resistance, while lower hardness improves impact toughness to reduce chipping during maintenance swaps.

Please provide the material specification (or select a catalog variant) if you need confirmed HRC and heat-treatment details for qualification.

Select this outside ring by matching the required date-marked outer diameter and the number of characters needed on the ring. The specification lists an applicable date marked outer diameter (mm) of 4 ~ 20, so you should choose the version that corresponds to your existing pin set’s cavity/core geometry and the target marking diameter.

• Outer diameter match (critical): Verify the OD of the date-marked feature in your tooling is within 4–20 mm, then select the outside ring variant sized for that OD.
• Character count: Confirm how many characters are required on the outside ring: 1 ~ 12. Choose the configuration that matches the cavity’s date layout (e.g., digit positions for day).
• Fixed engraving content: This product has Year = 26 and uses ※Designation by WOS, with WOS character formatting. Plan date coding accordingly; this variant is not for other years.
• Fit/tolerance: Because this is an outside ring only replacement for a heat-resistant date mark pin set, dimensional compatibility depends on the mating components and tolerances of your existing system.

When in doubt, cross-check the mating pin set model and OD profile before final assembly to prevent misalignment of the stamped characters.
