Ball Lock Ejector Punches - Light Duty, Inch

These light-duty ball-lock ejector punches are used in injection and assembly tooling where die ejection needs stable alignment over many cycles. The ball-lock point provides controlled retention, helping keep the punch position consistent during die opening and actuation.

• Automotive/industrial stamped components: suited for ejecting thin to moderate stock parts where controlled retention reduces misalignment-related scuffing and helps maintain repeatable ejection.
• Appliance and small housing assemblies: ideal for ejecting molded inserts or components from cavity surfaces when the tooling requires a dependable locking interface for precise punch travel.
• General-purpose die subassemblies: the inch format supports straightforward integration in American tooling layouts, with the XCN coating variant selected to support wear resistance in light-duty applications.

Choose the appropriate tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and shank diameter from the available range to match your die/cavity geometry and ensure stable ball-lock retention during ejection.

The provided specification data for this punch variant focuses on dimensional compatibility and the XCN coating used for light-duty wear support; a specific steel grade and heat-treatment cycle (e.g., quenched & tempered, nitrided) are not listed in the input. As a result, hardness (HRC) and toughness/wear trade-offs cannot be stated precisely from the available information.

• XCN coating: selected to improve surface wear behavior under light-duty stamping/ejection conditions, supporting stable actuation and retention.
• Material selection note: if your application demands higher wear resistance or higher temperature capability than typical light-duty service, confirm the underlying base steel grade and requested heat treatment with your supplier before finalizing tooling.

For best results, pair the coating choice with correct shank diameter and tip geometry to maintain alignment and minimize side-loading during ejection.

To select the correct ball-lock ejector punch dimensions, match the shank diameter D, length L, and the required tip shape to the punch-and-die assembly design.

• D (shank dia.) available in inch: 37 (0.3750), 50 (0.5000), 62 (0.6250), 75 (0.7500), 87 (0.8750), 100 (1.0000).
• L (coded inch length): 250 ～ 450. Use this to verify the required punch projection and travel clearance within the ejector plate and die layout.
• P, W, R dimensions: choose the set that matches your interface geometry. P is available as 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; W is 0.062–0.867; R is 0.007–0.4375, 0.007–0.625, 0.007–0.75, 0.007–0.875.

Because the input lists dimensional ranges rather than explicit tolerances, confirm fit/clearance requirements (ball-lock retention and side loading limits) against the mating ball-lock pocket features in your die design.
