Inch Standard Steel Ejector Punches - XAN DayTAN™ Coating

In inch-based progressive die and stamping tooling, these standard ejector punches are used to drive part release from stripper plates and die cavities during each press cycle. The XAN DayTAN™ coating is selected to support wear control at the punch tip and shank contact areas, helping maintain consistent ejection force and longer tool life when cycles are high.

For automotive connector and small stamped parts, engineers often choose specific tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) to match the required penetration and part geometry. The inch standard point length options (coded ranges within 150 to 400/600/625/650/700 depending on the configuration) improve repeatability in tool block alignment and ejection timing.

• Use in progressive dies where repeated punch action and predictable part release are critical.
• Use for stamping operations that experience abrasive wear at the punch working face and require stable ejector performance.
• Match the tip shape and P/W dimensions to control clearance, scoring risk, and penetration depth.

This product is specified as inch standard steel ejector punches with the XAN DayTAN™ coating for reliable ejection. While the underlying steel grade and target hardness (e.g., HRC) are not provided in the supplied data, the coating selection indicates a focus on wear resistance at the punch tip and shank engagement surfaces.

• Coating function: reduces surface wear during repeated ejection cycles to help maintain consistent punch action.
• Wear vs. toughness: ejector steel typically balances toughness (to avoid chipping) with surface hardness/wear capability; the coating improves wear behavior without requiring major geometric changes.

Manufacturing-wise, the punch is produced to inch standard geometries with controlled point and shank dimensions (including variable tip shape and point-length code ranges). The coating is applied to the working surfaces to strengthen cycle-to-cycle performance under stamping and progressive die conditions.

Select the ejector punch dimensions by matching the shank diameter, point length, and tip geometry to the mating guide/stripper pocket and the required penetration depth into the die cavity.

• Shank dia. (D): choose from 18 ~ 250 (in) to fit the intended tool block hole and maintain alignment through the stroke.
• Point length (B & L, coded inch): standard range 150 ~ 250, with alternate coded options such as 150 ~ 400, 150 ~ 600, 175 ~ 625, 225 ~ 650, and up to 250 ~ 700 depending on the selected alternate group.
• Tip shape: select from H, J, K, L, N, O, R, V, X, Y, Z based on the part geometry and controlled penetration needs.

For fit, account for practical clearance between the punch and its guide/stripper opening so the punch can move freely under press loads while avoiding excessive side loading. Use the P dimension range (0.05 ~ 1.625), and W range (0.062 ~ 0.5) to fine-tune the contact and edge engagement characteristics for consistent ejection.
