Point Larger than Shank Ball Lock Ejector Punch Blanks - Heavy Duty, Inch, XCDP Coating

This heavy-duty ball-lock ejector punch blank is used in injection mold tooling and die sets where stable punch locate control is critical during ejection. The larger-than-shank head geometry improves alignment under repeated press loads, helping maintain consistent ejection timing and preventing drift in the punch system.

• Automotive and electronics housings: In molds with high-cycle ejector actuation, the larger head supports steady punch positioning, which reduces risk of non-uniform ejection forces on inserts or thick-wall ribs.
• Industrial connector and bracket molds: Where multiple ejector points must register precisely, the punch’s stable locate behavior helps maintain repeatable part release across varying molding conditions.
• Long production stamping/die set applications: The XCDP coating is selected to improve wear performance, supporting stable punch operation over extended runs.

The provided datasheet specifies an XCDP coating and heavy-duty inch construction, focusing on wear control and long-run stability for ejector punch service. While no specific steel grade or hardness (HRC) is listed in the input data, the design intent is to pair tool-grade manufacture with a surface treatment that improves abrasion resistance at the ejector interface.

• XCDP coating: Used to enhance wear resistance during repeated ejection cycles and abrasive contact at the ball-lock components.
• Performance trade-off: Coated systems generally emphasize wear life; suitability should be confirmed for your load profile and expected ejection stroke rate.
• Available point shapes: Multiple tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow matching contact geometry to part features, complementing wear-focused coating selection.

If you need hardness, steel equivalence, or heat-treatment state for material approval, share your project spec and we can map it to the applicable material certification.

Select dimensions by matching the punch shank, length, and point geometry to your mold’s ejector plate arrangement and cavity/core contact requirements. This series provides inch-coded options for shank diameter D = 37 ~ 125 (in), length L = 250 ~ 450 or 275 ~ 450, and point/ball-lock interfacing parameters P = 0.376 ~ 1.251 (in), W = 0.062 ~ 1.083 (in).

• Step 1 (locate compatibility): Verify the required shank diameter range D matches your ball-lock tooling pocket and housings.
• Step 2 (stroke clearance): Choose L within 250 ~ 450 or 275 ~ 450 to maintain correct engagement without bottoming during maximum ejector travel.
• Step 3 (point contact): Select tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and use the provided R = 0.007 ~ 1 range to fit the part release surface.
• Tolerance/fit: Confirm your ball-lock fit target for stability; the larger-than-shank head is intended to improve locate stability, but final clearances should follow your assembly drawings.

Some parameters are fixed per variant (e.g., tip shape), while dimensional ranges (e.g., D, L, P, W, R) are configurable within the listed limits.
