Point Larger than Shank Ball Lock Ejector Punches | Light Duty, Inch | XVP Coating

This light-duty ball lock ejector punch variant is used in inch-based injection and stamping tooling where consistent blank release is critical, especially at higher cycle counts. The larger point relative to the shank helps improve ejection control by maintaining stable contact and timing with die set features during the stroke.

• Progressive/transfer blanking stations: Suitable for repeated ejection of small formed parts where the point-over-shank geometry supports smoother engagement and reduces the risk of hang-ups.
• Automotive and appliance stamping tooling (light duty): The XVP coating supports lower friction and wear, helping retain dimensional stability of the punch tip through production cycles.
• Tooling with frequent die set adjustments: The matched tip-to-shank design supports reliable blank release even when alignment or wear changes slightly over time.

The provided specifications identify this component as a light-duty ejector punch with an XVP coating, but no specific steel grade or hardness (HRC) is listed in the input data. As a result, material selection and heat-treatment details (e.g., quench & temper, nitriding, or pre-hardened condition) cannot be stated for this exact SKU without additional documentation.

What can be stated from the data: the XVP coating is intended to improve surface performance by reducing friction and wear under repeated actuation. The key trade-off in light-duty ejector designs is balancing tip stability and anti-wear behavior with the need for controlled ejection force and clean release.

• Coating focus: XVP helps reduce wear at the point during blank ejection cycles.
• Steel/heat treatment: Not specified in the provided parameters—confirm with the supplier for HRC and treatment state.

Selection is driven by matching the shank diameter (D), the overall coded length (L = 250 ～ 450), and the point geometry variables to your mold cavity/core and guide features. Start by choosing the shank diameter that fits the ball-lock pocket and guide: D is offered at 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), 1.0000" (100).

Then match the point-to-shank dimensions:

• P (in): 0.376 ～ 0.875, 0.501 ～ 1.25, 0.626 ～ 1.5, 0.751 ～ 1.5, 0.876 ～ 1.75, 1.001 ～ 1.75
• W (in): 0.062 ～ 0.867
• R (in): 0.007 ～ 0.4375, 0.007 ～ 0.625, 0.007 ～ 0.75, 0.007 ～ 0.875

Finally, confirm tolerances at the interface: ensure your ejector seat/pocket dimensions and ball-lock engagement will accommodate the chosen D and length L. Tip shape (H, J, K, L, N, O, R, V, X, Y, Z) should be selected to align with the part edge geometry for consistent blank ejection without gouging.
