Year 26 Date Mark Pin Sets Concave Inside Arrow

This date mark pin set is used in plate-exchange injection mold tooling where production needs frequent yearly date changes with minimal downtime. It is designed for applications such as packaging/labeling components, pharmaceutical and medical accessory housings, and automotive or industrial parts where lot/date traceability is molded directly into the part.

During plate side exchange, the concave “inside arrow” character provides high legibility on the molded surface, especially when space is limited on the date-recycle area. The press-fit installation helps maintain stable positioning of the pin set within the die insert, reducing character drift during repeated cycling.

• Yearly date update workflow: optimized for quick replacement in year-26 tooling
• Traceability marking: concave inside arrow engraving designation for clear on-part identification
• Stable operation: press-fit mounting supports reliable retention in the plate-side insert

With Year 26 and WOS engraving designation support, this variant is suited for tooling standardization across recycling/date-mark stations.

The provided product data does not specify a steel grade, heat-treatment state, or hardness value for this date mark pin set. As a result, material-property claims (e.g., HRC, wear resistance, or toughness trade-offs) cannot be stated from the available specifications.

For mold design verification, confirm the following with the supplied technical drawings/material certificate: pin steel grade, heat treatment condition (for example quenched & tempered or nitrided), and target hardness to assess wear under cavity pressure and repeated press-fit cycles.

• Steel grade & equivalence: required to evaluate wear vs. toughness balance
• Heat treatment: affects surface durability of engraved characters
• Hardness (HRC): helps predict rounding/chipping risk at the concave character edges

If you need a comparison between multiple material options, share the candidate steels/part numbers so the differences can be mapped to hardness and treatment.

Select dimensions by matching the pin geometry and engraving layout to the mold’s date-marking cavity or insert. This product’s fixed requirement is Year (year): 26 with engraving character designation by WOS, so the primary sizing work is aligning the pin count and marking depth options to your plate exchange station.

• Indication mark: choose Inside arrow character designation (concave inside arrow, inside arrow only)
• Arrow mark depth: set to Default or Shallow based on the desired character depth in the molded surface
• Quantity (No.): configure in the range 3 ~ 20 to cover the required date layout length and spacing

Because the installation is press-fit, ensure your plate-side insert pocket (hole/seat) dimensions are compatible with the pin’s specified fit in the manufacturer drawing. For reliable retention and repeatable engraving appearance, verify fit clearance/tolerance to prevent excessive looseness (character shift) or over-interference (damage to concave edges).

If your station uses a specific plate exchange interface, confirm whether dimensions are fixed or controlled by the plate-side design documents.
