Plate Side Exchange Date Mark Pin Outside Rings (Concave Character)

This plate-side date mark pin outside ring is used in injection mold tooling where date-related traceability must remain legible and quickly updatable during press servicing. In plate-exchange systems, the concave character outside ring improves visual readability on the stamped or molded date region while keeping the marking consistent across maintenance cycles.

• Date-recycle/traceability molds for consumer packaging: Designed for press-fit mounting so the ring retains position during repeated insert exchange, with a concave character form that helps maintain contrast in small-area impressions.
• Plate side exchange mark modules in automotive and appliance components: The plate side exchange orientation supports efficient removal and replacement, reducing downtime when production batches require new marking layouts while preserving alignment with the base date pin set.
• Industrial labeling features on housings and covers: The outside ring-only approach lets you reconfigure only the visible character ring, matching the tooling strategy for frequent SKU or batch updates.

The provided specifications for this date mark pin outside ring focus on dimensional and marking configuration rather than a specific steel grade or heat treatment state. As a result, the exact material chemistry, hardness (HRC), and heat-treatment method (e.g., through-hardening, quench-and-temper, nitriding) cannot be confirmed from the supplied data.

Engineering selection should therefore be based on your mold base and insert material strategy for press-fit parts: match the ring material to the expected wear regime (character abrasion from repeated contact) and the toughness needed to resist chipping during press-fit installation and plate exchange. If you can share the available material options or the supplier’s standard for this series, we can compare grades (e.g., tool steels commonly used for durable lettering) and recommend the most suitable hardness for your cycle count.

• Key requirement: press-fit retention with stable character geometry over repeated mold operation.
• Trade-off: higher surface hardness typically improves wear resistance but can increase brittleness if too high for the installation and load conditions.

Correct selection starts with the outside ring outer diameter D (mm): 3 ~ 20. Choose the D that matches the mating recess/hole diameter in your plate side exchange date pin set so the press-fit engagement provides stable retention without excessive installation force.

• Match the character count: the specified number of characters of the outside ring is 1 ~ 12. Ensure the ring layout length corresponds to your date window width for year/month/day presentation.
• Set month/day formatting: month indication supports X/Y/Z or 10/11/12 variants, and day can use the 1st digit, 10th digit, and 31 uniform divisions structure.
• Fixed year engraving: Year (year): 26 and engraving character designation ※Designation by WOS are fixed for this part variant, so verify your tooling scheme accommodates the fixed year logic.

Because tolerances are not specified in the input data, use the press-fit design tolerances provided by your plate exchange system (hole/insert fit class) to avoid either slip (too loose) or cracking (too tight).
