XCN Coated Point Larger than Shank Ball Lock Punches - Heavy Duty, Inch

These heavy-duty ball lock punches with a point larger than the shank are used in injection mold tooling where repeatable punch positioning and stable ball-lock retention are critical. The larger point geometry improves seating stability, helping maintain consistent transfer of force during operation across long production runs.

Common scenarios include:

• Automotive connector and bracket molds: used in stripper or insert-related punch tooling to support reliable ball-lock retention and reduce micro-movement under cyclic loading.
• Appliance and consumer device housings: applied where forming features must stay aligned during high duty cycles; the XCN coating helps protect the punch surface for improved wear behavior.
• General die and mold assemblies: selected when controlled punch retention and predictable engagement are required in punch tooling components.

The XCN-coated variant is particularly suited for environments with frequent contact and wear, while the inch-based heavy-duty design supports consistent forming results.

The provided product data specifies an XCN coating for wear protection, designed to support stable ball-lock retention during repeated duty cycles. While the exact steel grade and heat treatment state (e.g., pre-hardened, quenched & tempered, nitrided) are not included in the input, the coating’s role is to enhance surface durability and reduce wear at the punch point where engagement occurs.

From a manufacturing perspective, these punches are typically produced from tool steel blanks and then ground and fitted to the specified shank and point dimensions for proper ball-lock seating. The main trade-off is that higher wear protection at the contact face (from coatings like XCN) can be prioritized without changing the underlying toughness target of the base material.

• XCN coating: focuses on improved wear resistance under repeated sliding/contact.
• Hardness/toughness: not specified in the provided parameters; selection should follow your mold steel standard and expected loading.

To select the correct punch dimensions, match the shank diameter (D) and length (L) to the mating ball-lock system and the required travel engagement in your tooling. This series covers D = 37 ~ 125 in and L coded inch of 250 ~ 450 and 275 ~ 450, so confirm which length band your cavity/core space and holder stack-up require.

Then verify the tip/contact geometry:

• Tip Shape: choose from H, J, K, L, N, O, R, V, X, Y, Z based on the required point-to-shank relationship and seating form.
• P dimension: 0.376 ~ 1.251 in—align to the controlled engagement envelope in the ball-lock interface.
• W dimension: 0.062 ~ 1.083 in—confirm it clears adjacent features and supports the intended lock profile.
• R dimension: select from the available ranges 0.007 ~ 0.4375, 0.007 ~ 0.625, 0.007 ~ 0.75, 0.007 ~ 0.875, or 0.007 ~ 1 to achieve the desired corner/seat radius.

Where tolerances are critical for retention, rely on the supplier’s finished-dimension capability for the selected configuration; this input lists ranges, not specific tolerance values.
