Point Larger than Shank Ball Lock Ejector Punches - Light Duty, Metric, XCDP Coating

This light-duty, metric ball-lock ejector punch is used in injection mold and die tooling where the ejector must maintain positive retention and repeatable alignment under frequent cycling.

• Automotive interior component molds: In thin-wall or moderate-load ejector systems, the larger-than-shank point geometry supports the ball-lock function, helping reduce tip shift and improving consistent ejection timing.
• Packaging and consumer goods tooling: For housings and structural parts made with lightweight resins, the controlled wear behavior from the XCDP coating helps maintain stable engagement and surface condition over production runs.
• General-purpose medical-device housings (non-critical load): When compact metric die sets require reliable punch alignment, the point-to-shank form provides predictable engagement with the ejector plate/strip components.

Choose the available tip shapes (H through Z) and the matching shank diameter range to suit the cavity/core geometry and ejection stroke layout while keeping the system within light-duty performance needs.

The provided data specifies the XCDP coating on a light-duty ball-lock ejector punch, intended to support controlled wear and corrosion resistance during repeated ejector cycles. However, the steel grade, base hardness (HRC), and exact heat treatment state are not included in the supplied specifications, so those values cannot be stated from this product record.

In practical mold manufacturing terms, selecting a coated ejector punch variant typically prioritizes wear stability and dimensional consistency at the tip where friction and contact stress occur, improving long-term retention behavior of the ball-lock feature.

• Coating role (XCDP): Helps maintain stable wear behavior and improves resistance to corrosion at the engagement surfaces.
• Trade-off: Coated light-duty options are best matched to moderate loads; high-impact or very abrasive applications may require heavier-duty steel and heat-treatment choices (not specified here).

If you share the underlying material/heat-treatment sheet (or steel code), the hardness and temper/nitriding details can be added with certainty.

To select the correct ejector punch, match the shank diameter (D) and overall length to your mold’s ejector layout, then confirm the point geometry to your part-release needs.

• Choose D (shank dia., mm): Available D values are 13, 16, 20, 25, 32. Use the same diameter as your guide bush/ball-lock receiving pocket design to ensure proper alignment.
• Match lengths: Point length L1 is fixed at 19–30 mm. The overall punch length L is 80–100 mm (also shown as “80 �� 100” in the record). Verify your press-opening stroke and the required protrusion range in the ejector train.
• Select point shape: Tip shapes are H, J, K, L, N, O, R, V, X, Y, Z. Pick the shape that best supports your ball-lock seating and contact profile.
• Cross-check geometric limits: Confirm the P dimension range and W and R values against your receiving pocket clearances and part-side clearance.

Tolerance/fit data is not provided in the specification record; therefore, validate clearances using your ball-lock receiving pocket design drawings and any applicable supplier tolerance standards for ejector punches.
