JIS Standard XCD Coating Dayton Point Larger than Shank Ball Lock Punches

This Dayton point larger-than-shank ball lock punch is used in light-duty inch injection mold tooling where stable ball-lock engagement is required for reliable part ejection. The geometry increases engagement length versus the shank, improving how consistently the lock contacts the punch plate during cycling.

Automotive interior and trim components often benefit from this style when ejector loads are moderate and cycle-to-cycle repeatability matters. The larger point helps maintain consistent ejection force while reducing the risk of mis-seating during mold open/close.

Consumer goods and small appliance housings use ejector systems with compact space constraints; this variant’s inch-based shank diameter options (0.375–1.000 in) make it practical for tool-and-die build-ups. The XCD coating is suited for wear-prone operations, supporting longer service life under repeated ejection.

• Light-duty inch molds with ball-lock ejection
• Applications prioritizing stable alignment and consistent lock contact
• Wear-resistance needs addressed by XCD coating

The provided datasheet specifies a JIS Standard XCD coating on the Dayton ball-lock punch tip for improved wear behavior in service. While the steel grade and exact heat treatment condition (e.g., quench & temper, nitriding) are not included in the input data, the XCD coating indicates a surface-engineered approach intended to resist wear at the lock/contact zone.

In ball-lock ejector components, the key trade-off is surface durability vs. core toughness: coatings typically enhance abrasion and fretting resistance where the punch and plate interfaces rub, while the underlying tool steel must remain tough enough to prevent chipping under repeated mechanical loading.

• XCD coating: targets wear resistance at the engagement and sliding surfaces
• Material grade/heat-treatment not specified in the input—confirm during engineering verification

If you need a coating-to-steel comparison for your production wear profile, supply the target load/cycle count and we can recommend an appropriate base material/heat treatment combination for the mold steel standard you use.

Select this ball-lock punch by matching three dimensional groups: D (shank diameter), L (coded length 250–450), and the point-to-shank geometry defined by P, W, and R ranges. Because this is a “point larger than shank” design, the lock engagement depends on the point dimensions being compatible with the mating punch plate geometry.

• Choose D (in): 0.3750, 0.5000, 0.6250, 0.7500, 0.8750, or 1.0000
• Choose L (coded inch): 250 ～ 450
• Select tip shape: H, J, K, L, N, O, R, V, X, Y, Z to match your ejector layout

Then verify that your cavity/core and punch plate clearances allow the selected P (0.376–0.875, 0.501–1.25, 0.626–1.5, 0.751–1.5, 0.876–1.75, 1.001–1.75 in), W (0.062–0.867 in), and R (0.007–0.4375, 0.007–0.625, 0.007–0.75, 0.007–0.875 in). Keep in mind that ball-lock alignment is sensitive to fit; confirm functional clearances for the Jektole group (J4, J6, J9) and your plate tolerances to avoid mis-seating.
