M2 Steel Ball Lock Regular Ejector Punches

Ball-lock ejector punches are used in injection mold tooling where parts must be formed and then reliably separated from the mold face. The ball-lock retention style helps keep the punch aligned in the ejector system, reducing wobble during high-cycle ejection.

• Precision connector and small-part molds: Use the available tip shape options (H, J, K, L, N, O, R, V, X, Y, Z) to match different cavity contact profiles, supporting consistent forming and clean part release in light-duty tooling.
• Medical device housings (light duty): The M2 steel variant supports hardened wear resistance for repeat production, helping maintain punch surface integrity when ejecting thin features.
• Electronics enclosures and die tooling fixtures: The regular/ejector configuration is suited for standardized die tooling where stable retention and alignment improve ejection repeatability.

This light-duty configuration balances durability with precision, making it appropriate for molds that prioritize consistent cavity finishing and dependable ejection.

This series is offered in M2 steel (and an alternative PS4 option). For the M2 variant, the steel is selected for hardened wear resistance during repeat punch and eject cycles, which supports stable punch behavior across production runs.

• M2 steel: Typically used in hardened condition after quenching and tempering to achieve a wear-focused hardness level for tool life under sliding contact.
• PS4 (alternative): Provided as an option when designers prefer a different balance of wear resistance and toughness for specific light-duty die applications.

Because hardness (HRC) and the exact heat-treatment process state are not specified in the provided data, hardness and HRC values are not quoted here. Select the material variant based on expected wear, contact pressure, and cycle rate, then confirm the final heat treatment and hardness to match your process requirements.

To select the correct ball-lock ejector punch, match your ejector system and cavity/core requirements to the provided dimension ranges. Start with the shank diameter, D of 6 ~ 38 mm to ensure the punch fits the corresponding ejector bushing/support geometry.

• Choose point length (L1): available in 10–13, 10–19, 13–25, or 19–30 mm depending on how deep the contact point must reach.
• Select total length (L): available as 63–100, 71–100, or 80–100 mm to maintain correct engagement and stroke clearance.
• Match tip/contact profile: select one of the tip shapes H, J, K, L, N, O, R, V, X, Y, Z to form the intended contact geometry and ejection behavior.
• Confirm diameter/geometry features: use P (1.4–12 mm), W (1.4–14 mm), and the R dimension (0.2 mm) for locating/edge geometry compatibility.

Where cavity clearance and ejector travel are critical, verify that the selected L and L1 provide the required reach without interference. Tolerance/fit values are not provided in the input data, so use your mold-maker tolerancing and ejector bushing specifications during final fit verification.
