Outside Rings for PL Side Exchange Date Mark Pin Sets, Outer Corner Tapered

This outer ring component is used in PL side exchange injection mold tooling to form molded date-recycle characters reliably. In production, the press-fit mounting helps the ring maintain stable location during repeated insert exchange and molding cycles, which is critical for consistent month/day/year presentation.

Common scenarios include:

• Packaged goods date marking molds: the outer corner tapered profile assists alignment of the date marking pin set so molded characters remain centered and readable on labels or product surfaces.
• Automated date-recycle marking systems: the concave character engraving style (※Designation by WOS) supports clear molded month/day/year contrast, even when surface fill conditions vary.
• High-cycle PL side exchange tooling: the press-fit retention reduces loosening risk during frequent component swaps.

The keyed character designation and fixed year code (year 26) make this variant suited for standardized production date formats.

The provided data for this product focuses on geometry and character presentation; it does not specify the steel grade or heat treatment state. For accurate material selection (e.g., wear resistance vs. toughness), request the material certificate or drawing revision that lists the base steel and heat treatment.

When integrating into a date marking pin set, engineers should ensure the outside ring material supports:

• Wear resistance at the concave engraving/character edges to preserve readability over high cycles.
• Toughness to avoid chipping at the outer corner tapered transitions during press-fit assembly and exchange.

If alternative materials are available for the same geometry, compare their typical outcomes: hardened & tempered tool steels generally improve wear life, while lower hardness options may increase toughness but can accelerate edge degradation.

Selection is primarily driven by the outside diameter D (outer diameter) and the number of molded characters. Choose a ring with specified number of outside ring characters: 1 ~ 12 to match your required date string length in the PL side exchange design.

Match these specification points to the cavity/core layout:

• Month indication: fixed to 10/11/12, so ensure cavity logic routes the correct month digit set.
• Day digits: variable by outside ring character designation for Day (1st digit) and Day (10th digit).
• Year marking: fixed Year (year) = 26 (includes 4 years and 6 years formats in the provided variable mapping).
• Outer diameter D: select within 4 ~ 16 mm according to your locating bore or pocket size for the press-fit system.

Because this is a press-fit mounting style, verify the fit by using the supplier drawing for the interference/clearance targets; do not size only on D without confirming the mating tolerance class in your PL side exchange receiver.
