Point Larger than Shank Ball Lock Punches - Heavy Duty Metric

These heavy-duty metric ball lock punches are used in injection mold and die tooling where positive part retention and repeatable ejection are critical. The larger point geometry relative to the shank improves lock engagement under load, helping maintain consistent mechanical positioning during automated cycle times.

• Automotive connector and housing molds: Support stable retention of thin-to-medium features, reducing the risk of lock slip during high-speed ejection.
• Consumer and appliance enclosures: Improve reliability when ejector travel is frequent and molded parts must release uniformly without intermittent hang-up.
• Industrial sensor/valve components: The CRN coating is suited to longer production runs by enhancing surface durability at the working point that contacts mating components.

Choose the specified tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) when your locking interface requires a particular profile to match ball grooves or mating lock geometry in the ejector system.

The provided data specifies a CRN-coated construction designed to improve surface durability in the working region that experiences repeated contact during ejection. CRN (carbon nitride–based) coatings are typically selected to increase wear resistance and help maintain dimensional stability of the lock interface over longer cycles.

• Heat treatment: No base steel grade, hardness (HRC), or specific heat-treatment state (e.g., quenched & tempered, nitrided) is included in the supplied specifications.
• Wear vs. toughness trade-off: Coatings generally improve wear resistance at the contact surfaces, while the underlying tool toughness depends on the unlisted substrate steel and heat treatment.

If you require hardness and substrate metallurgy (e.g., for high-abrasion polymers or aggressive mold steels), confirm the steel grade and HRC with your Axiom Molds representative before finalizing tooling material selection.

Selection starts with matching the shank diameter D (mm) to your ejector system and mating component bores: available D sizes are 13, 16, 20, 25, 32, 40.

• Point/lock interface length: Use L1 (point length) = 19 to 30 mm to set how deep the lock point engages relative to the mating ball groove or retention feature.
• Total punch length: Confirm available L = 80 to 100 mm fits your mold stack-up and stroke envelope.
• Profile compatibility: Choose the required tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to match the locking geometry; then verify P (13.1 to 40.1 mm), W (1.57 to 34.73 mm), and R (0.2 to 16/19/20/22/25/28 mm ranges) align with the mating parts.

Tolerance and fit requirements depend on your ball-lock mating tolerances; therefore, maintain the same datum references used in your ejector housing/ball pocket drawings when transferring these dimensions into CAD.
