Ball Lock Ejector Punches - Light Duty, Inch

Ball-lock ejector punches like this light-duty inch option are used in injection mold tooling where stable, repeatable ejection depends on tight alignment of the punch and ejector system. Common scenarios include consumer and appliance housing molds with moderate cavity pressure, where consistent punch stroke helps prevent scuffing or uneven part release.

They are also suitable for automotive interior and bracket components that require reliable ejection timing and retention during cycling. The ball-lock style interface helps maintain secure seating of the punch, supporting smoother operation over repeated cycles.

For small-to-medium production runs using inch standard mold layouts, the XCDP-coated surface is well-suited to reduce wear at the contact region. Choose the variant with the appropriate shank diameter (D = 25–100 in) and coded length options (typically 200–600) to match your cavity/core ejection geometry.

• XCDP coating improves surface durability under repeated ejection.
• Ball-lock retention supports alignment stability during cycling.
• Inch tooling compatibility aligns with common light-duty mold designs.

This light-duty inch ejector punch is offered in M2 and PS4, enabling selection based on durability and wear requirements. M2 is a high-speed steel class commonly chosen for a strong balance of hardness and wear resistance. PS4 provides an alternative option when a different hardness/toughness balance is preferred for specific light-duty ejection duty cycles.

• M2: typically used where higher wear resistance is needed for repeated punch action.
• PS4: selected to match targeted performance for the mold’s expected cycle count and contact conditions.

The product uses an XCDP coating to enhance wear resistance at the working surface. While exact numeric HRC and heat-treatment state are not specified in the provided data, the coating is intended to improve surface durability, supporting longer service life compared with uncoated punches. For best results, pair the steel choice with the correct shank diameter (D = 25–100) and the coded point/length configuration.

To select the correct ball-lock ejector punch dimensions, start by matching your mold’s ejector plate/interface geometry to the required shank diameter (D). This series supports D = 25–100 in, so confirm the cavity/core and guide requirements before choosing a specific punch.

Next, choose the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) that best fits the contact features in your part and ejector layout. Then select the coded standard point length & L from the available inch-coded ranges: 200–400, 200–500, 200–600, or 225–600 depending on your configuration.

• For point length variants, use the available ranges for B & L (225–400, 225–500, 225–600) and C (225–500, 225–600).
• For D point length (coded), use 250–600 or 250–600 (as listed).

Consider fit and alignment: the P dimension is 0.05–0.75 and W is 0.05–0.437, which should be checked against your receiving pocket clearance. The series provides configurable tip shape/material/length options, while shank diameter and coded lengths define the primary dimensional compatibility with the mold.
