Ball Lock Ejector Punches Heavy Duty Inch X-Shaped Tip

These heavy-duty ball-lock ejector punches are used in injection mold tooling and related molding assemblies where precise ejection and repeatable blanking action are required. The X-shaped tip geometry helps control engagement with the mating ball-lock system, supporting stable contact during cyclic operation.

• Automotive connector and housing molds: Suitable for ejector functions that must withstand frequent stroke cycles and maintain consistent part release. The availability of M2 or PS4 hardened steels supports long-run wear resistance on the tip.
• Consumer and appliance enclosure tooling: Works well when molds require predictable ejection force distribution across ejector components. The punch’s heavy-duty construction and precision punch geometry help maintain fit and ejection performance as wear accumulates.
• Progressive die & mold stations (blanking/ejection): Designed for die and mold operations where controlled punch contact improves repeatability and reduces variability in output parts.

This series is offered in M2 and PS4 hardened steel selections to balance wear resistance and toughness for punch service. M2 (tool steel) is typically used where high wear resistance and good hot hardness support demanding cyclic cutting and punching applications. PS4 is commonly selected when stable punch performance and strong wear characteristics are prioritized for long production runs.

• M2: Hardened tool steel option for wear resistance; generally a higher-alloy approach aimed at maintaining performance under repetitive loading.
• PS4: Hardened steel option emphasized in the product description for stable performance and wear resistance in die and mold tooling.

The exact hardness (HRC) and the specific heat-treatment state (e.g., quenched & tempered, nitrided) are not provided in the supplied data, so verify with the item’s material datasheet before final selection.

Select the correct ball-lock ejector punch by matching the shank diameter (D), tip/point geometry, and the overall coded length to the mold cavity/core and the ball-lock interface. In this series, D ranges from 37 to 125 in (as provided), and the point length L is offered in coded ranges such as 250–500, 250–600, 275–600, or 300–600.

• Match D first: Ensure the shank diameter fits the guide/bore in your ejector system without interference.
• Confirm length code: Choose the L range that positions the X-shaped tip correctly to achieve reliable ejection travel and engagement.
• Width/height dimensions: Verify P (0.062–1) and W (0.062–0.5) against your mating features to maintain controlled contact.
• Tolerance & fit: Because fit depends on the press-fit or sliding arrangement in your mold, confirm required clearances with your housing/retainer bore tolerances before ordering.
