M2 Steel Ball Lock Regular Ejector Punches

These light-duty ball-lock regular ejector punches are used in metric injection molding tooling where reliable ejection and stable punch retention matter during repetitive cycles. The ball lock point helps maintain positive retention against deflection, while controlled blank ejection supports consistent cycle-to-cycle performance.

• Electronics and automotive connector housings: In progressive/transfer dies, the variants with different tip shapes help match the die geometry, supporting accurate alignment. The XNA coating reduces friction at the punch/die interface, which is helpful for high-frequency punching with minimal wear.
• Appliance and consumer product inserts: For light-duty cavities requiring frequent ejector actuation, the M2 steel backing provides dependable wear resistance and dimensional stability in routine production.
• Thin-wall part cores requiring gentle ejection: The point length and overall length ranges allow you to tune penetration depth and reduce risk of over-travel, keeping ejection repeatable.

Choose this variant when your tooling needs consistent retention plus extended wear life under light-duty metric punching conditions.

This product is offered in M2 steel (with an XNA coating for the specified variant). M2 is a high-speed steel known for good wear resistance in punching and sliding contact. For typical light-duty applications, it provides a balanced performance between hardness and toughness, helping punches resist abrasive wear while maintaining sufficient impact durability under repeated actuation.

• Material options: M2 is selected for dependable wear resistance in regular ejector punching. PS4 is also available per the specification set, which may be considered if your application prioritizes an alternate base steel choice while keeping the same dimensioning strategy.
• Coating effect: The XNA coating is used to reduce friction and help extend service intervals by lowering galling and sliding wear at the contact region.

Heat treatment state and exact hardness (HRC) are not provided in the available specification data, so they should be confirmed for your exact M2/PS4 lot and heat cycle.

Select dimensions to match the core/cavity ejector function and the corresponding die pocket/retention geometry. Key parameters provided for this series include D (shank dia.) 6–38 mm, overall L (length) ranges 63–100, 71–100, 80–100 mm, and L1 (point length) ranges 10–13, 10–19, 13–25, 19–30 mm. Tip shape is configurable as H, J, K, L, N, O, R, V, X, Y, Z.

• Match D to the guide/bore: Choose shank diameter within 6–38 mm to ensure proper fit with the ejector guide and to preserve alignment during ejection.
• Tune engagement with L1: Use the point length option (e.g., 10–13 or 19–30 mm) to achieve the required blank ejection depth without excessive penetration.
• Check interface dimensions: Verify P (1.4–12 mm) and W (1.4–14 mm) against the mating die features, since these govern contact and retention behavior.
• Confirm tolerance/fit: The dataset does not list tolerances; validate clearances for your ejector pocket and ball-lock mechanism during design.

Tip geometry variants should be selected based on your die design requirements to ensure proper retention and ejector alignment.
