Steel X-Tip Ball Lock Ejector Punches Light Duty Metric

These light-duty metric ball-lock ejector punches are used in injection-mold tooling and progressive-style molding systems where repeatable part blank ejection is critical. The X-shaped tip improves self-centering and stable alignment, helping maintain consistent knock-out forces over many cycles.

• Automotive & appliance connector housings: Suitable for ejection of small to medium inserts in metric cavity layouts where light-to-moderate punching cycles require reliable positioning.
• Medical device component trays and bases: The coating aimed at wear reduction supports longer service intervals in tooling that cycles frequently, helping reduce tip wear that can affect ejector timing.
• General electronics housings: Works in metric progressive or multi-station processes to maintain stable blank ejection using point-to-shank geometry for dependable die mounting fit.

The X-tip plus XN DayTride® coating combination is well-matched to light-duty production runs, balancing positioning stability with wear management.

The provided data specifies the punches as Steel ejector punches with an X-shaped tip and an XN DayTride® coating. While no specific steel grade (e.g., SKD61/H13 or AISI M2) or measured hardness (HRC) is included in the supplied parameters, the coating is the key functional material feature for extending tool life.

• XN DayTride® coating: Designed to reduce wear during frequent cycles, supporting stable ejection performance as contact surfaces polish and wear in.
• Steel base: Provides the required rigidity for the ball-lock mechanism and point-to-shank structure across the specified shank diameters (13–32 mm).
• Trade-offs: For light-duty metric applications, the coating prioritizes wear resistance without the need for higher-strength grades being specified in this dataset.

If you share the required steel grade/hardness targets for your mold material and cycle rate, we can map the best matching variant and heat-treatment state.

Select the ejector punch dimensions by matching the shank diameter (D), overall length (L), and point length (L1) to your die plate stack-up and ejector stroke requirements. This series includes D = 13, 16, 20, 25, or 32 mm, L1 = 19–30 mm, and L = 80–100 mm.

• Choose D first: Pick the shank diameter that matches the ball-lock bore and guides in your die set.
• Set stroke with L and L1: Verify that L (80–100 mm) and L1 (19–30 mm) fit within your punch return space while still reaching the required ejection position.
• Verify interface geometry: Use the provided P range (e.g., 13.1–32, 16.1–38, 20.1–40, 25.1–44, 32.1–50 mm depending on selection) and W (1.57–27.8 mm) to confirm clearance and working length against your die cavity/core.
• Consider R dimension: Confirm the specified R (0.2–16, 0.2–19, 0.2–20, 0.2–22, or 0.2–25 mm) matches the required tip curvature/relief.

Tolerances are not specified in the dataset; ensure your die design provides proper clearance for ball-lock movement and avoids binding during full stroke.
