Ball Lock Ejector Punches Heavy Duty Metric Tip O

These heavy-duty ball-lock ejector punches are used in injection mold bases and die-sets where the ejector must both locate accurately and release parts reliably. The ball-lock tip geometry is suited for pressurized cycles that demand stable blank retention during ejection.

• Automotive and industrial connector housings: Use them for consistent ejection stroke timing in molds with metric ejector systems, helping maintain repeatable part release from tightly controlled cavities.
• Consumer electronics enclosures: The supported point profile helps maintain engagement for dependable punch action, reducing risk of tip seating variation across long production runs.
• Packaging and appliance components: The heavy-duty ball-lock body is intended for robust blank location under frequent cycling, improving ejection consistency during high-throughput molding.

The selection of the metric tip “O” variant supports dependable blank location and ejection while maintaining engagement repeatability, making it a practical choice when tooling features are designed around ball-lock ejector interfaces.

The provided specifications for this item focus on the ball-lock interface geometry (tip shape, shank diameter, and point length), and do not list a specific steel grade, heat treatment, or hardness value. As a result, the exact material composition, HRC level, and any heat-treatment state (e.g., quenched & tempered, nitrided) cannot be stated from the supplied data.

What can be confirmed is that the heavy-duty punch body and the tip O point profile are engineered for stable engagement, which indirectly supports wear resistance and toughness requirements in high-cycle ejection. When comparing alternatives within the same ball-lock category, the primary functional differentiation from your dataset is the tip shape selection (H, J, K, L, N, O, R, V, X, Y, Z) and the shank diameter (D).

• Material/heat treatment: Not specified in the input dataset.
• Performance trade-off: Typically, higher hardness improves wear resistance but may reduce toughness; confirm with the supplier’s technical sheet for the final steel condition.

Select the ejector punch dimensions by matching the shank diameter and the point geometry to your mold cavity/core and the mating ball-lock feature. This product is available in tip shapes including O, and in D (shank dia.) values of 13, 16, 20, 25, 32, 40 mm.

• Point length (L1): fixed at 19 to 30 mm. Choose L1 to ensure full engagement and proper ejection reach without bottoming.
• Total length (L): fixed at 80 to 100 mm. Verify stack height and clearance in the ejector system so the punch stroke completes reliably.
• P dimension: variable 13.1 to 40.1 mm—use it to align the punch’s effective locating envelope with the holder/ball-lock recess.
• W and R dimensions: variable W = 1.57 to 34.73 mm and R = 0.2 to 16, 0.2 to 19, 0.2 to 20, 0.2 to 22, 0.2 to 25, 0.2 to 28. These affect the engagement surface curvature and clearance—match to your ball-lock interface design.

Tolerance/fit note: Your mold drawings must use the manufacturer’s specification for acceptable clearance/interference at the ball-lock interface. Because tolerance values are not provided in the dataset, confirm tolerances for the final selection.
