Year 26 Date Mark Pin Sets with Beveled Outer Ring

These date mark pin sets are used in injection mold tooling where a molded identification code must be updated on a regular schedule without changing the entire date system. The plate side exchange layout is particularly suited for packaging and consumer-goods date labeling, where Year/Month/Day indicators help traceability for production lots.

• Automotive and industrial components: the press-fit mounting supports consistent positioning of the date characters during high-cycle molding.
• Medical device housing or accessory tooling: the beveled outer ring with corner taper improves repeatable installation on the plate side, helping keep the code readable during handling and inspection.
• Appliance housings and small electronics enclosures: plate side exchange with the inner arrow design simplifies date changes when switching from one day to the next.

The built-in year value (Year = 26) and adjustable arrow mark depth (Default/Shallow) help align the marking appearance to your product’s visual spec while keeping the insert stable during assembly.

The provided datasheet focuses on the date-marking configuration and dimensional range, but it does not specify a steel grade, heat treatment state, hardness (HRC), or surface treatment for this MISUMI series. As a result, the material properties and tempering/nitriding recommendations cannot be stated from the supplied information.

• Material/heat treatment: not specified in the input data.
• Hardness & wear resistance: not provided; therefore, hardness trade-offs (e.g., toughness vs. wear) cannot be quantified here.
• Manufacturing process: the set is engineered for press-fit mounting and plate-side exchange, but the specific machining/grinding or coating process is not detailed.

If you share the insert’s material grade (or a reference drawing/spec sheet), we can map it to an equivalent steel standard and add the correct heat treatment and HRC targets for reliable wear and character edge durability.

To select the correct date mark pin set, match the required marking layout and the outer diameter D (mm) = 3 ~ 20 to your mold plate opening and character design. This series has a fixed Year = 26, so the remaining variability is handled by the year-month-day indication format.

• Choose indication mark configuration: select among Year/Month, Month, Day (1st digit), and Day (10th digit). The year span options are provided as Year (6 years) and Year (4 years), while Month indication supports X/Y/Z or 10/11/12 formats.
• Set arrow mark depth: pick Default or Shallow depending on the desired legibility and the surface appearance constraints of your molded part.
• Verify press-fit fit: the outer diameter range (3–20 mm) must correspond to the press-fit hole/seat diameter on the mold plate. Since tolerances are not specified in the input data, confirm clearances using your plate machining drawings to avoid excessive insertion force or looseness that can affect alignment.
