Extended Range Ejector Punches Metric XAN DayTAN™ Coating

These extended-range ejector punches are used in injection and stamping-style mold tooling where ejector travel must remain stable over a long stroke. Their extended-range geometry helps maintain contact and promote straight ejection, reducing the risk of stick-slip during cycling.

• Automotive connector and housing tooling: Suitable for ejecting thick features or multi-part components where the ejector system needs consistent return and controlled wear under repeated production loads.
• Appliance and industrial enclosure dies: Works well for blanking and forming dies that require dependable punch return across longer strokes, especially when close-clearance operation can increase friction and galling.
• High-cycle production of formed sheets: The XAN DayTAN™ coated contact surface is designed to support controlled wear and help reduce galling, improving consistency over time.

This variant is engineered to perform in close-clearance tooling environments by combining a long-stroke punch profile with a wear-focused coating.

The provided datasheet specifies the XAN DayTAN™ coated surface intended for controlled wear and reduced galling. However, no steel grade, heat-treatment state (e.g., quenched & tempered, nitrided), or target hardness (HRC) is included in the input parameters, so these values cannot be stated reliably.

• Coating role: The XAN DayTAN™ layer is used to improve tribological behavior at the punch-to-holder and guided-contact interfaces, supporting consistent performance in production cycles.
• Wear vs. toughness trade-off: In general, hardened substrate plus a wear-resistant coating improves resistance to abrasion, while toughness is primarily governed by the underlying steel and its heat treatment; specific substrate hardness and toughness cannot be confirmed from the current data.

If you share the steel grade or certification sheet for series 250301827852, we can document the exact equivalent grade, HRC range, and heat-treatment condition for engineering sign-off.

To select the correct extended-range ejector punch, match the punch’s shank diameter (D) and overall length (L) to your punchholder and cavity/core clearance requirements. This series supports D = 40, 45, 50, 56, 63 mm and L = 63 to 100 mm.

• Point penetration / contact control: Use the fixed L1 = 25 to 30 mm to ensure the working point reaches the intended ejecting contact depth without bottoming in the guide system.
• Geometry matching: Select the tip shape among H, J, K, N, O, R, V, X, Y, Z based on part geometry and the required contact area.
• Guiding and clearance: Choose the correct P and W dimensions within the available ranges (e.g., P: 20–39.95 up to 40–62.95 mm depending on the configuration; W: 8–39.95 up to 12–62.95 mm) to fit the ejector track and interface envelope.
• Draft/relief (R): Confirm the R range (0.2 to 19.975 up to 0.2 to 31.475 mm) to maintain clearance at the transition zones.

Tolerance values are not provided in the input; verify fit to your punchholder bore and alignment features using your standard mold tolerances for this punch diameter.
