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

This heavy-duty ball-lock ejector punch point, with an inch-based geometry where the point is larger than the shank, is intended for tooling that demands reliable retention and repeatable ejection cycles.

• Automotive connector and bracket molds: Use this variant in punch press and injection mold inserts where consistent engagement is critical for maintaining parting quality under high cycle counts.
• General industrial forming and punching: The XVP coating is suited to resist abrasive wear from repeated contact, helping stabilize ejection performance in production environments.
• Electromechanical housing fixtures: The ball-lock design supports secure locking to the assembly, reducing the risk of retention drift when ejector loads fluctuate.

The larger-point geometry improves positioning and punch-to-opening engagement, while the XVP coating supports wear resistance for stable operation over long runs.

The provided series specification focuses on geometry and XVP surface performance rather than a specific steel grade or heat-treatment condition. For this reason, hardness (HRC), nitriding/quenching parameters, and exact wear–toughness trade-offs cannot be stated from the supplied data.

What can be confirmed is that the XVP coating is selected to improve wear resistance during repeated punch/ejector cycles, targeting abrasive contact areas at the point and engagement surfaces.

• Coated vs. uncoated: The XVP-coated variant is intended to reduce abrasive wear and extend service life under high-frequency loading.
• Trade-off: When comparing to uncoated tooling, coating performance typically favors wear resistance, while final toughness behavior remains dependent on the underlying steel and heat treatment (not specified here).

Select the ejector punch point-to-shank geometry by matching the shank diameter (D), length (L), and coded dimensions to the tool’s cavity/core features and retention method for ball-lock assemblies.

• Shank diameter (D): Choose from 37 ~ 125 in per the available variants to fit the receiving bore and ball-lock seating location.
• Length (L) (coded inch): Use the available ranges 250 ～ 450 or 275 ～ 450 to ensure stroke clearance and full engagement without bottoming.
• Point/feature dimensions: Match P (0.376 ~ 1.251 in), W (0.062 ~ 1.083 in), and R (0.007 ~ 0.4375 / 0.007 ~ 0.625 / 0.007 ~ 0.75 / 0.007 ~ 0.875 / 0.007 ~ 1 in) to the mating opening geometry and contact profile.

Because tolerance values are not provided, confirm clearance/fit requirements with your ball-lock retention specs and your toolmaker’s standard tolerances; treat all coded inch lengths as fixed configuration options within the listed ranges.
