XCDP Coating Ball Lock Ejector Punches - Light Duty, Inch

These light-duty ball lock ejector punches are used in injection and press tooling where reliable die-side ejection is required but contact loads are moderate. The ball-lock action helps maintain repeatable coupling to mating components, improving ejection timing consistency across production cycles.

• Progressive/transfer die applications (light duty): Match the punch shank diameter range (0.3750" to 1.0000") and choose a tip shape (H–Z) to suit the die cavity/core layout while supporting stable alignment during part release.
• Thin-wall or precision stamped features: The XCDP coating is selected to help reduce wear at sliding/engagement surfaces, helping maintain smooth ball-lock movement and consistent ejection over time.
• Multi-station assemblies with mixed ejector geometry: Select the coded length (L = 250–450 in inch-coded units) to avoid interference and keep stroke clearance, while the configurable P and W ranges allow adaptation to specific lock-ball engagement dimensions.

Overall, the XCDP-coated variant is suited for tooling that prioritizes controlled wear and dependable ejection performance under light loads.

The provided specification set focuses on geometry and the XCDP coating, but does not list the underlying steel grade or measured hardness (HRC). For material selection, confirm the base steel and coating system from the manufacturer’s technical data sheet for the corresponding series/variants, especially if you need hardening targets for wear and bending resistance.

• Coating role (XCDP): Used to improve surface wear resistance at the ball-lock engagement and sliding interfaces, supporting smoother movement and longer tool life in lighter duty press/injection support tooling.
• Heat treatment: Not specified in the input data—verify whether the punches are provided in a pre-hardened condition or require case/coating-related treatments.
• Trade-offs: Without the base grade and HRC, compare options by target hardness versus toughness: higher hardness typically improves abrasion resistance but can reduce toughness if the tool sees shock or misalignment.

If you share the steel grade and tolerance class for this series, the hardness and heat-treatment guidance can be made fully specific.

Select dimensions by matching both mechanical clearance and ball-lock engagement geometry to your die cavity/core and mating components. Start with the D (shank dia.) range—0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), or 1.0000" (100)—to ensure the punch can be guided without side loading.

• Length selection: Choose the coded L in the range 250–450 (coded inch). Verify stack-up against die thickness and stroke requirements so the ball lock fully engages and ejects without bottoming.
• Engagement geometry (configurable): Match P within the available ranges (0.376–0.875, 0.501–1.25, 0.626–1.5, 0.751–1.5, 0.876–1.75, 1.001–1.75) and set W (0.062–0.867) to your mating lock-ball/coupler dimensions.
• Tip contour: Select Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z) to fit the cavity contact needs and part release surface.
• R (radius) selection: Use the available R ranges (0.007–0.4375, 0.007–0.625, 0.007–0.75, 0.007–0.875) for profile match and stress reduction at contact.

Tolerance/fit guidance depends on the mating part’s tolerance class; confirm the die-side holes or bushings’ spec before finalizing the D and engagement dimensions.
