Ball Lock Ejector Punches Heavy Duty Inch

These heavy-duty inch ball lock ejector punches are used inside injection mold tooling to drive and position die components during ejection. The ball-lock point retention helps maintain stable seating at the tip, reducing the risk of point micro-movement that can lead to inconsistent ejection force or surface scuffing.

• Automotive connector and housing molds: Suitable for high-cycle ejection where repeated contact requires abrasion resistance; the XNT DayTiN® coated tip supports wear control over long runs.
• Appliance and consumer electronics enclosures: Works well in dies with complex cavity geometries because selectable tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) help match the die face for improved alignment.
• Production punching/copy-die operations: The inch heavy-duty format supports robust die ejection behavior under demanding cycle conditions, with improved point retention to help sustain consistent punch penetration.

Overall, the coated, heavy-duty variant is engineered for reliable ejector performance where tip wear and retention stability are critical.

The provided metadata specifies an XNT DayTiN® coated tip for wear resistance, but it does not list a specific steel grade or heat-treatment state (e.g., quenched & tempered, nitrided) for the punch body. As a result, the exact base-material hardness (HRC) and temper condition cannot be stated from the given data.

In practice, TiN-type coatings (including DayTiN®) are selected to improve abrasion and surface wear resistance at the tip where repeated sliding/contact occurs during ejection. This generally trades off against very high thermal shock resistance in some coating systems, so stable tooling temperature and proper lubrication are still important.

• XNT DayTiN® coated tip: Emphasis on wear resistance at the point for robust ejection cycles.
• Base steel: Not specified in the input; therefore hardness/toughness comparisons across grades are not available here.

For exact HRC targets and heat-treatment recommendations, confirm the steel specification from DAYTON/Lamina with your quoting request.

Use the catalog dimensions to match the punch to your mold cavity/core layout and ejection stroke requirements. Key shank and retention-related sizing parameters are D (shank diameter): 37 ~ 125 in and L (length, coded inch): 250–450 or 275–450, depending on the variant.

• Choose tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to align with your die face geometry and contact profile. This is the primary compatibility lever for consistent ball-lock engagement during ejection.
• Select shank diameter (D) to fit the punch bore in the ejector plate or guide system; ensure the bore clearance and alignment support smooth travel.
• Match overall length (L) so the tip reaches the required ejection position without bottoming or excessive overhang.
• Verify fine geometry using P (0.376 ~ 1.251), W (0.062 ~ 1.083), and R (0.007 ~ 0.4375 / 0.007 ~ 0.625 / 0.007 ~ 0.75 / 0.007 ~ 0.875 / 0.007 ~ 1) where applicable.

Tolerance/fit guidance is not provided in the input data; size to your established ejector bore tolerances for stable guidance and reliable ball-lock retention.
