Metric Point Larger than Shank Ball Lock Ejector Punches - Heavy Duty XVP Coating

Ball-lock ejector punches are used in injection mold tooling and die casting forming operations where repeatable ejection force is required under tight alignment. This heavy-duty metric point variant is suited for die casting and forming molds that cycle frequently and experience abrasive wear on the ejector tip and ball-lock interface.

In automotive component molds (e.g., brackets and housings made from engineered alloys), the point-larger-than-shank geometry helps maintain stable ball-lock engagement, reducing the risk of partial lock-up during high-speed cycling.

For high-cavity production dies used with steel or abrasive-forming conditions, the XVP coating is selected to reduce friction at the sliding interfaces and improve punch durability between maintenance intervals.

• Point geometry improves ball-lock engagement stability during ejection.
• XVP coating supports wear resistance and controlled ejection.
• Metric sizing supports consistent fit in metric die sets.

The provided configuration specifies a heavy-duty ball-lock ejector punch with an XVP coating, selected to improve surface performance at the sliding and wear-critical regions (point and shank/ball-lock interface).

While the exact steel grade and base hardness are not included in the input data, the coating intent is clear: enhance wear resistance and reduce friction to support longer service life under repeated ejection cycles. In practice, this typically benefits abrasion resistance while maintaining sufficient toughness for interrupted loading during die cycling.

• XVP coating: targets reduced friction and improved durability at the ejector point.
• Trade-off to consider: any coating system may reduce surface roughness control requirements but must be matched to expected abrasion and thermal cycling.
• Heat treatment state and HRC are not specified here; confirm with the supplier/technical drawing for verification.

If multiple materials/coating stacks are offered for this series, choose based on expected wear rate and cycle count, prioritizing coating performance when lock stability and tip endurance dominate.

Select this punch by matching the shank diameter (D), overall length, and the point geometry required for reliable ball-lock retention in your mold design.

From the provided specs, use D = 13, 16, 20, 25, 32, or 40 mm. Choose the point length L1 = 19 to 30 mm based on how far the punch must extend into the ejection zone while still clearing adjacent features.

The overall length is L = 80 to 100 mm; confirm it matches the ejector stroke and the ejector guide/retainer stack height in your assembly.

• Pick tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to match cavity/core contours and ejection contact requirements.
• Use Jektole group (J6, J9, J12) to align with your ball-lock/retention design family.
• Validate P (13.1–50 mm depending on D configuration), W (1.57–34.73 mm), and R (0.2–16/19/20/22/25/28 mm ranges) so the point profile fits the mating pocket without interference.

Tolerances are not specified in the input; for fit-critical ball-lock interfaces, rely on the official drawing and your die set tolerance stack to prevent mislock or accelerated wear.
