Inch Light Duty Point Larger than Shank Ball Lock Ejector Punches

This inch Light Duty ball-lock punch point larger than shank variant is used in injection mold tooling where stable, repeatable ejection is required under high cycle rates. The larger point geometry increases ball-lock engagement, helping maintain positive retention between the punch and ejector system during operation.

• Automotive connector and sensor housings: suited for long-run ejection of small to medium plastic parts where consistent stroke-to-stroke positioning prevents misalignment or lock slip.
• Consumer electronics enclosures: the secure ball-lock construction supports predictable ejection in multi-cavity molds with frequent press cycling.
• General manufacturing Light Duty molds: used with inch Light Duty ejector punch blanks when economical wear performance and reliable locked ejection are prioritized.

An XNA coating improves wear resistance, supporting longer service intervals while maintaining consistent punch performance.

The provided product specifications describe geometry and coating behavior (including an XNA coating for tool life), but they do not include the underlying steel grade, hardness (HRC), or heat-treatment state. For accurate metallurgical selection, confirm the supplied steel designation and target hardness with the manufacturer or your receiving inspection data.

In ball-lock punch applications, the key property balance is wear resistance for repeated sliding/lock surfaces versus toughness to resist chipping at the pointed region. Coatings such as XNA typically shift the balance toward improved wear life by reducing surface abrasion and friction.

• Coated tool surfaces: enhanced wear resistance for economical maintenance cycles.
• Substrate requirements (not specified): should be selected for sufficient toughness at the tip to avoid edge damage during ejection loading.

If multiple steel/material options exist for this series, compare them by verifying stated HRC, coating process compatibility, and suitability for your ejection force profile.

Selection is driven by matching the punch point geometry to the ejector system dimensions and the mold cavity/core requirements for the required ejection footprint. This series provides inch Light Duty sizing with D (shank diameter) options of 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), and 1.0000" (100).

• Length (L): choose from coded inch length 250 to 450 to suit stack-up and safe clearance to the backing plate.
• Point engagement dimensions: match P within the listed 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 select the corresponding tip shape (H, J, K, L, N, O, R, V, X, Y, Z).
• Geometry fine-tuning: set W within 0.062–0.867 and R within the offered ranges (0.007–0.4375, 0.007–0.625, 0.007–0.75, 0.007–0.875).

Because tolerance data is not provided here, confirm allowable clearances on your ball-lock receiver and guide the final fit using the vendor’s dimensioning/tolerance tables for the chosen tip shape and D size.
