Ball Lock Ejector Punches Heavy Duty Inch X-Shaped Tip

Ball lock ejector punches like this are used inside injection mold and die-casting tooling where repeatable ejection force and secure retention are critical. The X-shaped tip helps distribute and break adhesion at the eject interface, improving consistency when the punch works through deeper core/cavity regions.

• Die casting: Suitable for heavy-duty die inserts that experience high surface loading; the ball-lock retention supports stable positioning through frequent cycles.
• Automotive and industrial housings (injection molding): Designed for plastics molding ejector assemblies where controlled stroke-to-stroke ejection reduces risk of sticking and tip wear.
• Precision multi-cavity tooling: The inch-coded standard point lengths (250–600 coded inch ranges) help match tooling layouts that require consistent ejection geometry across cavities.

For demanding setups, this variant offers either M2 steel for wear-focused performance or PS4 where an alternative wear/robustness approach is preferred, with XNAP coating support to further enhance surface durability.

This series is available in two steel options: M2 and PS4. M2 is a high-speed steel commonly selected for wear resistance in ejector applications, while PS4 provides an alternative grade choice for durability in tooling environments where wear behavior and toughness needs must be balanced.

• M2: Typically selected for strong wear-focused performance; compatible with XNAP coating support when increased surface hardness/tribological performance is desired.
• PS4: Intended as a grade alternative for heavy-duty molding/die tooling, supporting engineers who need a different wear/toughness trade-off versus M2.
• Coating: The product metadata indicates XNAP coating support; when used, it can improve surface wear resistance at the tip where contact and sliding are most severe.

For detailed heat-treatment state and final hardness (HRC), refer to the specific configuration/quote sheet for the selected material and coating option, as these parameters are not provided in the input data.

To select the correct ball lock ejector punch, match the shank diameter (D), tip geometry, and coded point length to your mold core/cavity ejector layout. This series lists D = 37 ~ 125 (inch) and multiple tip shape options: H, J, K, L, N, O, R, V, X, Y, Z.

• Choose the tip shape: Select the required contact/ejection geometry for your part ejection profile; the heavy-duty X-shaped tip is targeted for improved ejection consistency.
• Select point length (coded inch): Use the appropriate range for L / B / C / D coded lengths: 250–500, 250–600, 275–600, or 300–600. Confirm which coded length family applies to your drawing specification (L, B&L, C&L, or D).
• Verify interfacing dimensions: Dimensions P = 0.062 ~ 1 and W = 0.062 ~ 0.5 should be checked against your ejector bore/retainer design to avoid binding or misalignment.

Because tolerance and fit values are not included in the provided specifications, validate fit using your housing/bore tolerance standard and perform a dry-run check in the assembled ejector system.
