Metric Light Duty Point Larger than Shank Ball Lock Ejector Punches

This metric light-duty ball-lock ejector punch variant is used in injection mold die sets where dependable ejection depends on consistent ball lock retention and controlled wear. The larger point relative to the shank supports improved ball engagement, helping maintain stable stroke guidance through repeated starts and stops.

• Automotive & industrial connector molds: Ideal for ejector systems that handle moderate loads; the increased point size improves ball lock seating and reduces the risk of retention loss during ejection.
• Consumer product housings with routine production: Suitable where frequent maintenance cycles and light duty operation require an ejector punch that remains dimensionally stable; the CRN coating targets sliding wear at the contact interface.
• General-purpose die builds using metric components: The metric form factor matches standard die assembly practices, reducing retrofit complexity when maintaining existing ejector layouts.

Choose the light-duty configuration when your application prioritizes secure ball lock holding and predictable wear behavior rather than maximum heavy-load abrasion performance.

The provided configuration specifies a CRN coating for improved wear resistance during ejection-related sliding contact. While the underlying steel grade and hardness (HRC) are not specified in the supplied data, CRN coatings are typically selected to enhance surface durability under repetitive motion and fretting/sliding conditions.

• Coating effect: The CRN layer helps reduce wear at the point and ball-lock contact surfaces, supporting consistent retention behavior.
• Heat treatment relevance: In ball-lock punch assemblies, the base steel is usually supplied in a hardened condition to resist deformation; however, the exact heat treatment state for this product is not listed in the provided specifications.
• Trade-off: Coated punches can show excellent surface wear performance, while the base material’s toughness and strength still govern resistance to bending and impact from ejector events.

If you need a specific steel grade and target hardness for your load profile, confirm the requested base material and heat-treatment specification with your Axiom Molds representative.

Selection starts by matching the ejector system geometry to the punch’s shank and point features. Confirm the D (shank diameter) requirement first: available shank sizes are 13, 16, 20, 25, and 32 mm. Use the matching ball-lock punch type for your die build, including the Jektole group (J6, J9, or J12) and the required tip shape (H, J, K, L, N, O, R, V, X, Y, Z).

• Point length (L1): fixed at 19–30 mm depending on the selected size.
• P dimension: select within the provided ranges that correspond to your chosen size (e.g., 13.1–32, 16.1–38, 20.1–40, 25.1–44, 32.1–50 mm).
• Overall length (L): fixed at 80–100 mm to fit your mold thickness and ejector stroke clearance.

Pay close attention to fit around the ball lock housing: ensure your selected W (1.57–27.8 mm) and R (0.2–16 up to 0.2–25 mm depending on option) correspond to the die’s internal notch/radius features. Tolerance values are not provided here, so validate final clearance using your die drawing and ball-lock pocket dimensions.
