Ball Lock Ejector Punches Light Duty, Inch, XNA Coating

These light-duty ball-lock ejector punches are used in injection mold and press tooling where stable strip-out and repeatable part ejection are required. The ball-lock geometry supports consistent engagement and release during cycling, helping maintain positioning accuracy in inch-based assemblies.

• Automotive and appliance housings (light-duty cavities): The light-duty point style promotes controlled ejection in relatively shallow features, where minimizing ejector wobble improves surface finish and cycle reliability.
• Consumer product press tooling: Use in applications requiring standardized inch ejector components; the ball-lock interface supports quick alignment with mating pockets and reduces inconsistent strip-out.
• Multi-cavity molds with frequent changeovers: The XNA coating variant provides added surface protection for wear-prone ejection zones, supporting longer service intervals under normal light-duty conditions.

Choose this variant when you need inch sizing, ball-lock compatibility, and enhanced wear behavior from the XNA coating for reliable ejection in light-duty production.

The provided configuration specifies an XNA coating intended to improve surface protection and wear behavior at the ejector’s working interface. The underlying steel grade and exact heat-treatment state (e.g., quench & temper, nitriding) are not listed in the input data, so hardness and microstructural specifics cannot be stated precisely.

• Coating effect (XNA): Helps reduce adhesive/abrasive wear at the ball-lock engagement area, supporting more stable ejection performance over repeated cycles.
• Wear vs. toughness trade-off: In coated ejectors, maintaining a sound substrate toughness is important to avoid chipping at the punch tip under shock loads; coating primarily improves the surface while the base material governs toughness.
• Material options: No alternate steel grades are provided in the metadata for comparison.

For hardness (HRC) confirmation and heat-treatment verification, request the substrate material certificate for series 250300512773.

Select dimensions by matching the ejector’s shank and working profile to the mold’s ball-lock pocket requirements. This light-duty inch series provides a D (shank dia.) range of 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), or 1.0000" (100), which must fit the corresponding receiver bore/pocket.

• Length (L): Choose coded inch length L = 250 ～ 450 to reach full stroke coverage without excessive protrusion.
• Profile matching: Verify 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) and W (0.062～0.867 in) against the ball-lock geometry of the mating components.
• Radius features: Confirm R (0.007～0.4375, 0.007～0.625, 0.007～0.75, 0.007～0.875 in) to ensure correct contact and engagement.

Tolerances/fit ranges are not provided in the input; use standard ejector pocket clearances for light-duty inch tooling and validate fit with the specific mating part geometry.
