Product Guide
Application Scenarios+
This heavier-duty ball lock ejector punch style is used in injection mold tooling and die work where ejection reliability and steady guidance are critical. The larger point geometry (relative to the shank) is especially helpful when contacting parts through short, controlled strokes, improving engagement during actuation.
- Automotive connector and housing molds (inch tooling): Use for stable ejector operation in compact mold bases; the secure ball-lock retention reduces the risk of punch movement during repeated cycles, while the XNAP-coated surface targets abrasive wear.
- Consumer electronics housings and clips: Suitable for designs that require consistent ejection force distribution; the larger point improves contact consistency during part release.
- Industrial fixtures and short-stroke die ejectors: The coded inch length ranges support standardized build planning across tooling sets, helping match tool-side assembly without redesigning the ejector layout.
Material & Process Details+
The provided data specifies the XNAP coating but does not list an exact steel grade, hardness level (HRC), or heat-treatment state. For mold engineers, this means the wear-performance expectation should be tied to the coating system rather than a confirmed substrate specification.
- Coating focus (XNAP): Designed to improve surface wear resistance for longer service life under repeated ejector cycling and sliding contact.
- Wear vs. toughness trade-off: Coatings generally enhance wear resistance at the surface; substrate toughness and core strength will still depend on the underlying punch steel selection, which is not specified here.
- Material comparison: If you are selecting between different punch bodies, prioritize confirmed substrate grade and heat treatment (e.g., quenched & tempered or nitrided) from the quote/spec sheet to balance toughness and tool life.
If you need exact HRC and heat treatment for qualification, request the full material certificate for series code 250301836896.
Sizing & Selection Guide+
Select the punch configuration by matching the tip shape, D (shank diameter), and coded inch length L to your cavity/core and ejector-retention stackup. This family covers multiple tip geometries (H, J, K, L, N, O, R, V, X, Y, Z) to fit different part-release contact requirements.
- Shank diameter D (in): choose within 37 ~ 125 to fit your ball-lock components and guidance features.
- Length L (coded inch): use 250 ~ 450 or 275 ~ 450 depending on how much protrusion and travel are needed from the ejector plate to the part contact point.
- Point and feature dimensions: verify P (0.376 ~ 1.251) and W (0.062 ~ 1.083) against your contact geometry and clearance envelope; confirm R within the applicable range (0.007 ~ 0.4375, 0.007 ~ 0.625, 0.007 ~ 0.75, 0.007 ~ 0.875, or 0.007 ~ 1).
Because tolerance data is not provided here, treat these values as sizing ranges to be checked against your mold drawings and the mating ball-lock housing specs. Tip shape and coded length are configurable per order; D and the listed P/W/R ranges must match the tool-side design for correct fit.
