MISUMI Date Mark Pin Sets for PL Side Exchange (10/11/12 Indication)

This date mark pin set is used in PL side exchange injection mold tooling where the cavity side needs serviceable, repeatable date coding. The set provides a fixed 10/11/12 month indication with a concave character layout, helping maintain legible engraving on molded parts even during frequent maintenance cycles.

• Automotive and industrial housings: When molded components require traceability for warranty and batch control, press-fit retention stabilizes the marker during part ejection and handling.
• Medical device packaging components: The consistent month marking supports documentation and lot tracking; the concave character geometry promotes reliable surface readability on small features.
• Electronics and connector accessories: For molds that use side exchange modules, the inside arrow designation paired with an outside ring character set streamlines changeover while keeping the month code fixed.

With selectable outer diameter D (4–20 mm) and configurable arrow depth (default/shallow), engineers can match the marking intensity and size to cavity engraving requirements while keeping the month code standardized.

The provided specification details focus on character design and dimensional parameters; no steel grade, hardness (HRC), or heat treatment state is specified for this date mark pin set. As a result, material properties such as wear resistance, toughness, and any quench/temper or surface treatment cannot be stated from the available data.

For mold design reviews, treat material selection as a compatibility step with your expected wear and cycle conditions. Confirm whether the pins are made from a standard date-marking tool steel and whether they are through-hardened, pre-hardened, or nitrided before final tool validation.

• Wear vs. toughness trade-off: Hardened/surface-treated grades typically improve engraving wear but may reduce impact toughness if the hardness is high.
• Manufacturing process: This product is characterized by precision engraving/character formation (concave character, inside arrow, outside ring) and press-fit mounting geometry; machining/finishing quality will strongly influence marking crispness.

Choose the pin set dimensions to match the cavity/core engraving envelope and the required character scaling. The critical dimensional parameter is the outer diameter D (4–20 mm), which should be selected to fit the corresponding press-fit features in the PL side exchange insert structure.

Confirm the character configuration before installation:

• Month indication: Fixed to 10/11/12 indication (no alternate month set for this SKU).
• Outside ring characters: Select the required number of outside ring characters within 1–12.
• Arrow depth: Use Default or Shallow to control marking depth and readability.

Fit considerations: Because mounting is press-fit, the hole/seat geometry in the mold should be engineered for retention without overstressing the marker. Use your mold supplier’s standard press-fit tolerance practice for the chosen D (4–20 mm), and validate marking visibility against part surface finish and ejector/knockout conditions.
