Inch Dayton XNAD Coated Ball Lock Ejector Punches - Light Duty

This light-duty ball lock ejector punch family is used in inch injection mold tooling where reliable, repeatable ejector actuation is required without heavy wear loads. The XNAD coated surface supports stable punch travel and locking engagement, making it well suited for compact die sets and cost-sensitive maintenance programs.

• Automotive connector and small housing molds: Use when frequent press cycles demand positional stability from the ball-lock mechanism while keeping parting lines clean and ejection consistent.
• Consumer product housings and brackets: Ideal for molds that prioritize economical replacement and predictable ejection behavior, especially where shank guidance prevents deflection.
• Light-duty transfer or insert molding tooling: Beneficial when controlled material ejection is needed; the point larger than shank geometry helps manage material flow at the ejector interface.

Choose the appropriate tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to match die/core undercuts and ejection clearance, leveraging the coated wear surface to extend service life.

The provided variant specifies an XNAD coating to enhance surface wear resistance for light-duty ejector operation. While the exact steel grade, base hardness (HRC), and heat treatment state are not included in the supplied specifications, the coating is intended to reduce abrasive wear at the locking and sliding interfaces and to maintain stable fit over repeated cycles.

• Wear resistance vs. toughness: Coated surfaces typically improve sliding life; ensure ejector dimensions and guidance support alignment to avoid edge loading that can stress the underlying steel.
• Manufacturing process relevance: Coated ejector punches are typically ground and finished to maintain consistent ball-lock engagement; the coating then forms the final wear surface.
• Heat treatment: No specific quench & temper, nitriding, or pre-hardened state is listed in the provided data—confirm base steel and heat treatment during engineering review.

If you need a specific hardened base (e.g., for higher impact loading), request the steel grade and hardness profile for the exact series code.

Select dimensions by matching the ejector punch to the mold cavity/core hole geometry and the required ejection clearance. This series provides fixed and variable sizes, so begin with the shank diameter and length, then verify the point and engagement geometry.

• Shank diameter D (in): Choose from 0.3750, 0.5000, 0.6250, 0.7500, 0.8750, 1.0000.
• Ejector length L (coded inch): Select within 250 ～ 450 (coded length). Match to your ejector stroke and stack-up to ensure full actuation without bottoming.
• Point/engagement geometry (P, W, R): Use the available ranges to set clearance and ball-lock interface fit. P varies in blocks (e.g., 0.376～0.875, 0.501～1.25, 0.626～1.5, up to 1.001～1.75). W ranges 0.062～0.867, and R ranges from 0.007～0.4375 up to 0.007～0.875 depending on configuration.

Because tolerances and fit classes are not specified in the input data, maintain proper guide and locking clearance per your mold design standards, and verify that chosen D and tip shape (H–Z) won’t interfere with cavity/core surfaces.
