Extended Range Ejector Punches Metric (M2 Steel) X-Tip

Extended reach ejector punches are used in injection and compression mold tooling where the ejector actuation point must reach into a deeper cavity or through a longer core structure. The extended length range (L 63–100 mm) helps maintain stable engagement during part release, reducing the risk of short-travel ejection in long-stroke or deep-draw tooling.

• Automotive connector and terminal molds: Pair this geometry with long-reach slide or ejector layouts to support consistent ejection across repeated press cycles. The X-tip guidance improves contact control for reliable punch alignment with small landing features.
• Consumer housings and appliance cavities: In deep cavity housings, the increased reach supports even stripping forces and helps prevent partial ejection when draft angles and surface finish vary.
• Medical device housings (low-to-medium volume): Use where stable, repeatable ejection is required to avoid part deformation at release; the wear-resistant steel supports longer intervals between maintenance.

This punch series is offered in M2 (with options including A2). M2 is a high-speed steel equivalent to AISI M2, typically selected for strong wear resistance in ejector applications where repeated sliding contact and impact loads are present.

• Hardness & performance trade-off: M2 generally provides high hardness and excellent abrasion resistance, which helps preserve punch tip geometry over time. The trade-off is that, compared to some lower-alloy steels, toughness may be less forgiving under extreme shock—proper alignment and controlled ejection forces are important.
• Heat treatment state: Select M2/A2 in a hardened condition (commonly quenched and tempered) to achieve the target HRC for stable dimensional retention and wear life.
• Material comparison: A2 is often chosen when a balance of toughness and wear resistance is preferred; M2 is typically favored for maximum wear performance.

Select the punch based on reach requirements first, then match shank and tip interface details. The shank diameter D is available in 40, 45, 50, 56, 63 mm. Choose the overall length L (63–100 mm) to cover the cavity depth plus mechanical clearances for safe stroke completion.

• Point length control: The point length L1 is fixed at 25–30 mm, so the effective engagement depth is primarily driven by L.
• Interface dimensions: Match P (20–39.95, 25–44.95, 30–49.95, 35–55.95, 40–62.95) and W (8–39.95, 9–44.95, 10–49.95, 11–55.95, 12–62.95) to the receiving bore/guide and the desired tip contact position.
• Tip geometry: Tip shapes are configurable (H, J, K, N, O, R, V, X, Y, Z); verify that the X-tip landing matches your stripper/ejector contact feature.

Because exact clearances and fit depend on your ejector guide and punch pocket, confirm tolerances to ensure free movement without binding during cycling.
