Metric Ball Lock Ejector Punches - Heavy Duty, XAN DayTAN™ Coating

These heavy-duty metric ball lock ejector punches are used in injection mold tooling where reliable ejection and stable punch-to-ball engagement are critical. The ball-lock point geometry helps maintain consistent contact during cycling, supporting controlled release of molded parts.

• Automotive connector and housing molds: Suitable for long production runs where ejector wear can cause inconsistent stroke and part hang-up. The XAN DayTAN™ coating is selected to improve wear resistance under repetitive sliding contact.
• Appliance and metal-insert molded components: The larger point geometry supports stable forming contact when parts require precise ejection from steel die sets.
• General progressive and injection molding tooling: Configured for metric builds, enabling repeatable ejector action with standardized shank and point proportions.

With available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z), you can match the contact and ejection characteristics to the ball-lock system layout for the mold.

The provided specification focuses on geometry and coating rather than a named tool steel grade. In this product family, wear performance is primarily supported by the XAN DayTAN™ coating, which is engineered for long-run durability in ball-lock applications where repeated sliding and friction occur.

• Wear resistance: The coating is intended to reduce abrasive and friction-related degradation of the punch tip, helping maintain forming contact and ejection consistency over time.
• Toughness trade-off: While coatings improve surface wear behavior, they rely on a mechanically sound punch substrate for toughness and resistance to chipping or galling under load.
• Heat treatment state: Not specified in the provided data; selection should be confirmed with the supplier or incoming material certificate when defining maintenance intervals and load limits.

If you need a direct comparison against other variants (e.g., uncoated or differently coated punches), evaluate expected contact pressure and cycle count, since coating performance is typically the differentiator when the core steel grade and heat treatment are similar.

Select the punch dimensions by matching the mold’s ball-lock ejector system requirements to the available metric ranges for this series. Use the D (shank diameter) to fit the ejector housing/guide and to ensure proper engagement alignment with the ball-lock mechanism.

• Choose D (mm): Available shank diameters are 13, 16, 20, 25, 32, 40.
• Set overall length L (mm): Fixed range is 80 ～ 100 to suit stack-up length and ejector travel.
• Match point length L1 (mm): Fixed 19 ～ 30 to control tip penetration and the effective contact area during ejection.
• Select geometry via P and W: Use P ranges (e.g., 13.1～32 for one configuration, 16.1～38, 20.1～40, 25.1～44, 32.1～50, 40.1～56) and W (1.57 ～ 34.73 mm) to match the ball-lock interface profile.
• Verify R (mm): Corner/edge radius is 0.2 ～ 16 / 19 / 20 / 22 / 25 / 28 depending on configuration.

Tolerance/fit specifics are not listed in the provided data; confirm allowable clearance and fit class with your ball-lock housing drawings before finalizing the selected variant and tip shape (H, J, K, L, N, O, R, V, X, Y, Z).
