Inch XNP Coating Point Larger than Shank Ball Lock Ejector Punches - Light Duty

This light-duty ball-lock ejector point is designed for inch-sized injection mold tooling where stable punch guidance and consistent retention are required. The larger-than-shank point geometry helps center the ejector action in ball-lock punch assemblies, reducing wobble and improving repeatability in high-frequency cycles.

Common scenario 1: automotive connector housing molds—use this variant with XNP coating to support wear resistance at the ejector tip during frequent parting and ejection. The point size larger than the shank improves alignment through the mold platen and keeps the ball-lock mechanism working reliably.

Common scenario 2: consumer electronics enclosure molds—the light-duty design is well suited for smaller ejector loads where efficient ejection and dimensional repeatability matter. Select the tip shape and P/W dimensions to match the existing ejector arrangement while maintaining smooth travel.

Common scenario 3: general-purpose plastic components—inch-coded lengths (L) simplify configuration across standard ejector layouts, supporting efficient ejection without over-specifying heavier duty punches.

• XNP coating supports wear resistance for long service life in light-duty applications
• Larger point than shank improves punch stability and guidance during ejection
• Inch-coded length options align with standard ejector arrangements

The provided datasheet for this series focuses on geometric selection and XNP coating usage; it does not specify the underlying steel grade or exact heat treatment cycle. For accurate metallurgy and hardness verification, confirm the steel grade and heat treat status for series code 250300512818 with the supplier documentation.

XNP coating is specified for this light-duty ejector punch point and is intended to improve wear resistance at the contact and sliding regions during repeated ejection. In typical ejector-point applications, the coating enhances surface durability while the core material provides the required toughness for ball-lock retention and mechanical loading.

• Hardness and heat treatment state (e.g., quenched & tempered) are not provided in the input data
• Wear resistance emphasis is driven by XNP coating for light-duty production cycles
• Potential trade-off: higher surface wear resistance coatings can increase surface rigidity; proper sizing (P/W/R) helps maintain smooth guidance

Select this ball-lock ejector point by matching the shank diameter (D), coded length (L), and the point geometry parameters (P, W, and R) to the mold cavity/core ejector system and the ball-lock pocket design.

• D (shank dia.): choose one of 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), or 1.0000" (100)
• L (Length, coded inch): select within 250 ～ 450 to align with your ejector stack height and ball-lock assembly depth
• P dimension: pick the matching range band—0.376～0.875, 0.501～1.25, 0.626～1.5, 0.751～1.5, 0.876～1.75, or 1.001～1.75
• W dimension: 0.062～0.867
• R dimension: 0.007～0.4375, 0.007～0.625, 0.007～0.75, or 0.007～0.875

To ensure proper fit, verify that your ball-lock punch housing and mating pocket are dimensioned for the chosen D and that the point larger-than-shank profile does not interfere with nearby ejector features. Where your design tolerances are tight, confirm the supplier’s drawing-level tolerances for P/W/R (not provided in the input) before finalizing the cavity/core interface.
