Ball Lock Ejector Punches Light Duty Metric XNAP Coating

These light-duty ball lock ejector punches are used in injection mold tooling where controlled ejection, stable alignment, and repeatable punch seating are required. They are well suited to automotive connector and sensor housing molds, where short-cycle production benefits from reduced wear at the punch tip and dependable ball-lock retention during frequent open/close cycles.

• Point geometry (larger point than shank) promotes secure lock-in, limiting movement and improving ejection control.
• XNAP coating reduces friction and helps resist abrasive wear from sliding motion against the guide/support components.

They are also commonly selected for appliance and consumer product mold tools built around metric punch sets, because the metric configuration supports straightforward integration with standard assemblies.

Material and heat-treatment details are not explicitly provided in the supplied product metadata. However, this variant specifies an XNAP coating applied to a ball-lock ejector punch substrate to improve tribological performance in sliding service.

• Wear resistance vs. toughness trade-off: surface coatings generally enhance abrasion/fretting resistance, while the base steel’s toughness primarily governs resistance to chipping under shock ejection loads.
• Manufacturing process (functional): the ejector punch is produced with the defined metric shank diameter and point length, then finished and coated so the coated surfaces maintain fit while reducing friction.

If you need hardness (e.g., HRC) or a specific steel grade/heat-treatment state for this series, confirm with Axiom Molds using the series code 250301837505.

Select this ejector punch by matching the ball-lock geometry and the overall length to your core/cavity and ejection stroke requirements. The product supports D (shank dia.) values of 13, 16, 20, 25, 32 mm, so choose the shank diameter that matches your punch set and ball-lock receiving bore.

• L1 (point length): fixed at 19 to 30 mm.
• L (overall length): available in 80 to 100 mm (also shown as “80 �� 100” in the data).
• P dimension: corresponds to configuration; ranges include 13.1–32, 16.1–38, 20.1–40, 25.1–44, 32.1–50 mm depending on the selected D and variant.
• W and R: select per the required clearance/edge condition; W is 1.57–27.8 mm and R is 0.2–25 mm depending on the option.

Account for coating and fit by using the specified metric sizes and the ball-lock retention features (point larger than shank) to maintain consistent seating without excessive clearance.
