Metric Ejector Punches XNAD Coating X Tip

Metric ejector punches are used in injection mold tooling where reliable part release is required, especially in close-space mold systems that limit available clearance around the cavity. This punch variant uses an X tip geometry to support controlled contact during ejection, helping stabilize the punch-to-part interaction and reduce inconsistent stroke behavior.

In automotive connector and small housing molds, ejector forces must be transmitted through compact tool layouts. The X-tip contact style is suited to maintaining predictable penetration and ejection timing, while the XNAD coating helps support smooth punch action under production cycling.

For consumer electronics enclosures and other fine-feature plastic parts, repeatable ejection helps prevent surface marring and uneven part lift. Selecting this family for metric shank assemblies supports consistent fit within standard mold builds and helps maintain dependable ejection performance across multiple cavity zones.

These metric ejector punches are available in M2 and PS material options to match different wear and toughness requirements. M2 is a high-speed steel (commonly equivalent to AISI M2 in performance intent) known for strong wear resistance; it is typically used where abrasion from repeated ejection cycles is a primary concern.

PS provides an alternative balance for applications that emphasize processing stability and consistent cutting/press-fit behavior during tooling maintenance.

• Heat treatment state: choose a quenched & tempered or other production-ready hardened state as supplied for ejector punch service (final hardness depends on the selected material grade and heat treatment batch).
• Hardness & trade-offs: higher hardness generally improves wear resistance and tip longevity, while slightly lower toughness can increase sensitivity to edge chipping if misalignment or excessive side load occurs.
• Coating effect: the XNAD coating further supports smooth punch action and wear reduction at the contact surface.

Select an ejector punch size by matching both the shank diameter (D) and the overall length (L) to the cavity/core and ejector plate layout. For this series, the D (mm) range is 5 ~ 32, so choose the closest standard shank that fits the metric ejector bushing/guide hole in your tooling.

Then match the required ejection reach using the point length (L1) and total L. Available L1 ranges are 13 ~ 19, 19 ~ 25, and 25 ~ 30 mm, while L ranges include 40 ~ 80, 40 ~ 100, 50 ~ 100, and 63 ~ 100 mm.

• Confirm the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) aligns with your part contact geometry needs; the X tip option supports controlled contact.
• Verify the P (1.3 ~ 16 mm) and W (1.6 ~ 10 mm) dimensions against your tool clearance envelope.
• R is specified as 0.2 mm, so plan your corner/edge clearance around that radius.
