Concave Date Mark Outside Ring (10/11/12 Indication)

This concave date mark outside ring is used in injection mold tooling where date-recycle or gas-vent related date marking must remain readable after molding. It is typically integrated into length-adjustable date mark pin assemblies, with the ring acting as the outside ring only that carries the character form while the pin core remains unchanged.

• Automotive and industrial parts marking: Apply the 10/11/12 character indication on molded housings or components requiring month verification during incoming inspection. The concave form helps maintain legibility under varying surface lighting.
• Packaging and closure-related molding: In molds using modular date-mark systems, the outside ring simplifies servicing—engineers can replace the ring to correct character specification without reworking the pin core geometry.
• Assembly line quality control: The WOS engraving designation supports traceable character specification when multiple marking options are used across product families.

The provided product data specifies geometry and engraving designation, but it does not include a steel grade, hardness (HRC), heat-treatment state, or coating. For this reason, Axiom Molds recommends verifying the material specification from the related date-mark pin and the vendor’s material certificate before committing to a tooling material strategy.

• Material selection: Date-mark inserts commonly pair a tough core with wear-resistant character-form surfaces; however, the exact grade for this ring is not listed in the supplied parameters.

If multiple materials are offered for the compatible date mark pin system, engineers should compare them based on required cycle life, expected abrasive conditions, and thermal exposure from the molding process. Confirm hardness and treatment (e.g., quenched & tempered or nitrided) in the datasheet associated with the pin to balance wear resistance against toughness.

Select the outside ring size by matching the outer diameter (D) to the compatible length-adjustable date mark pin system. Available D values are 6, 8, and 10 mm; choose the diameter that corresponds to the pin mounting interface used in your mold design.

• Match to cavity/core layout: Use the pin diameter selection to ensure the ring sits correctly on the character area and does not interfere with adjacent mold features.
• Concave character form: Ensure sufficient clearance around the character form so that molding does not cause flash that could blur the 10/11/12 marking.
• Engraving designation compatibility: The engraving character designation is specified as ※Designation by WOS. Confirm your WOS designation requirement before finalizing the character set for production.

Tolerance and fit details are not provided in the supplied data. For press-fit or locating features, use the tolerance class specified by the compatible pin/mounting system to maintain repeatable character placement during adjustment and replacement.
