DAYTON Point Larger than Shank Ball Lock Punches - Light Duty

These light-duty ball-lock punches are used in injection mold tooling wherever positive retention and repeatable engagement are needed—especially in systems that employ ball-lock mechanisms for rapid component mounting and removal. The point geometry larger than the shank helps improve tool engagement, which supports stable ball-lock retention during continuous press cycles.

Common scenarios include:

• Automotive connector and terminal molds: The larger point supports consistent retention through repeated ejection/punching operations in production environments.
• Consumer electronics enclosure tooling: The point/ball-lock interface remains reliable when switching jobs frequently and when stripping conditions vary across part features.
• Light-duty medical device housing molds: When tight assembly repeatability is required, the point profile supports dependable lockdown without overcomplicating the tool stack.

When paired with XCD coating options, the punch surface is better suited for wear reduction during repetitive cycles, helping maintain dimensional stability of engagement features.

The provided configuration specifies geometry and optional surface protection, but does not state a steel grade or heat-treatment condition in the input data. Therefore, the material-property guidance below focuses on the documented feature: the XCD coating option and its functional role in mold tooling.

• XCD coating: selected to improve surface wear resistance under repetitive punching cycles, which can reduce point rounding and help preserve ball-lock engagement consistency.
• Hardness/toughness trade-off: coatings generally enhance wear resistance at the surface; however, substrate toughness requirements still matter for preventing chipping under misalignment or shock loading.
• Heat treatment: since the grade and heat state (e.g., quenched & tempered, nitrided) are not specified, confirm the supplier’s material datasheet for hardness in HRC if you need to match wear targets to your cavity/core steel.

If multiple materials are offered for this series, compare them by measured HRC, coating adhesion approach, and expected wear under your cycle count and abrasive contamination level.

Use the series’ variable dimensions to match your mold cavity/core requirements and the ball-lock pocket geometry. This series offers shank diameter (D) values of 13, 16, 20, 25, 32 mm, and each D corresponds to a valid P dimension range and point length window.

• Select D first to align with your punch bore/holder constraints for the ball-lock interface.
• Match L1 (point length): fixed at 19–30 mm depending on your selected option; ensure the point fully enters the engagement zone without bottoming.
• Set total length L: fixed at 80–100 mm, and verify it fits the tool stack height and ejection/stripping clearance.
• Verify P and W: choose the configuration so P (13.1–32 / 16.1–38 / 20.1–40 / 25.1–44 / 32.1–50 mm) and W (1.57–27.8 mm) correspond to the cavity/core pocket profile and stripping conditions.
• Confirm R (0.2–16, 0.2–19, 0.2–20, 0.2–22, 0.2–25 mm) to ensure the corner radius matches your mating features and reduces stress concentration.

Because tolerances are not provided in the input data, rely on your mold assembly drawings for clearance; when you change D or tip shape, re-check fit in the ball-lock seat to avoid binding or inadequate retention.
