M2 Steel Ball Lock Ejector Punches Light Duty XAN DayTAN™ Coating

These light-duty ball-lock ejector punches are used to actuate ball-lock ejection systems inside injection mold tooling, helping maintain consistent removal of parts from the cavity. Their shank diameter range (D 6–38 mm) and point-length options support different die layouts and stroke lengths.

• Automotive connector and housing molds: In repeat-cycle production, the ball tip geometry provides stable contact for reliable ejecting of thin features and insert-like parts, reducing risk of sticking during discharge.
• Consumer electronics enclosures: Use them where moderate wear resistance is sufficient; the M2 construction balances tooling life with cost for light-duty runs and frequent mold changes.
• Small medical and lab device housings: The XAN DayTAN™ coating supports smoother surface behavior under cycling, which can help maintain ejection consistency for fine-detail molded components.

This series offers M2 steel as a primary option for light-duty ejector punches. In general tooling practice, M2 (high-speed steel family) is selected for its combination of wear resistance and adequate toughness for repeated sliding/contact at the punch tip; the trade-off is that higher hardness grades may be more sensitive to severe shock loading than tougher steels.

The punches are supplied with the XAN DayTAN™ coating, intended to improve surface performance during repeated cycles. Depending on your production requirements and supplier processing, the M2 variant is typically delivered in a hardened condition suitable for ejector service, with subsequent coating for reduced friction and improved durability.

• M2 vs. PS4: M2 is specified for this series as the standard light-duty material; PS4 is offered as an alternative material option when your application prioritizes different wear/toughness balance or supplier matching.

Select the ball-lock ejector punch dimensions to match the ball-lock interface and the available guide/shank space in the die. Start with D (shank diameter) = 6–38 mm and choose the length pair that fits your stack and ejection stroke requirements.

• Tip/point length (L1): available ranges include 10–13 mm, 10–19 mm, 13–25 mm, and 19–30 mm. Use L1 to set the engagement depth for dependable ball-lock actuation.
• Overall length (L): options include 63–100 mm, 71–100 mm, 80–100 mm. Verify clearance to ejector housing, backing plate, and any adjacent components.
• Geometry selection: the tip shape can be H, J, K, L, N, O, R, V, X, Y, Z to match your ball-lock pocket profile.

For fit, ensure the selected P (1.4–12 mm) and W (1.4–14 mm) values match the corresponding pocket/ball-lock dimensions in your core/cavity tooling. Maintain the specified series tolerances at installation surfaces where ejector alignment affects repeatability.
