M2 Steel Ball Lock Ejector Punches Heavy Duty XCDP Coating

These heavy-duty ball lock ejector punches are used in injection mold tooling where repeatable blank ejection and stable retention are required. In automotive and appliance connector housings, the ball-lock design helps maintain punch position during high-cycle ejection, reducing the risk of part hang-up and improving cycle consistency.

• Precision blank ejection in insert molds: Works with die insert systems that require controlled ejection force and accurate point geometry.
• Thin-wall and high-surface-finish parts: The stable retention supports uniform release, helping avoid scuffing or uneven separation.
• Production molds with frequent cutting cycles: The heavy-duty M2 steel base paired with the XCDP coating targets improved surface durability for longer service life.

Choose the M2 steel variant with the XCDP coating when you expect sustained mechanical loading and abrasive wear at the punch point/shank interfaces, while still needing the precision needed for tight assembly in ball lock systems.

This variant is specified in M2 steel, a high-speed steel grade commonly selected for tooling that must balance wear resistance and hot hardness characteristics. It is paired with a heavy-duty XCDP coating to enhance surface durability where the punch point and shank experience sliding contact and repeated ejection cycles.

• Wear vs. toughness: M2 provides strong wear resistance, but like other high-speed steels it typically requires proper heat treatment and careful polishing to maintain edge/point integrity.
• Heat treatment state: The provided specifications confirm M2 steel with XCDP coating; a specific hardness value and exact heat-treatment condition (e.g., quenched & tempered or pre-hardened) are not stated in the available data.
• Alternate material option: PS4 is also listed as an available material choice; select PS4 when your application priorities differ (e.g., coating/tribology targets), and validate performance against your wear profile.

For final qualification, confirm coating adhesion and wear performance under your mold contact conditions.

To select the correct ball lock ejector punch, match the shank diameter and length to your mold cavity/core and retainer geometry. The shank diameter D is specified as 10 ~ 40 mm, so choose the D that matches your ball-lock pocket and guide/bushing requirements.

• Choose point length (L1): Available L1 ranges are 10 ~ 19, 13 ~ 25, and 19 ~ 30 mm. Use L1 to control how far the point enters the part or blank release area.
• Select total length (L): Options include 63 ~ 100, 63 ~ 125, 71 ~ 125, and 80 ~ 125 mm. Pick L to ensure correct projection while avoiding interference with the return stroke or surrounding components.
• Tip shape and dimensions: Tip shapes are H, J, K, L, N, O, R, V, X, Y, Z. Also align P (1.5 ~ 12 mm) and W (1.5 ~ 14 mm) to your required point geometry; R is fixed at 0.2 mm per the data.

Tolerance and fit are not provided; ensure your mold design accounts for your toolmaker’s standard ball-lock fit clearances and verify assembly stability for the selected Jektole group (J4M, J6M, J9M, J12M).
