M2 Steel Ball Lock Ejector Punches Light Duty XVP Coating

These light-duty ball lock ejector punches are used in injection and transfer tooling where reliable blank ejection is required, but loads are moderate. The ball lock geometry helps maintain stable retention in the punch holder, supporting consistent ejection force over repeated cycles.

• Automotive & electronics connector components: Suitable for ejecting molded inserts or plastic blanks from light-to-medium cavity pressures; the M2 steel base provides a durable working surface while the XVP coating helps resist abrasion and reduce galling during fast production.
• Appliance housing and general consumer parts: Used in multi-cavity molds where many ejectors must remain aligned; the point-to-shank proportions support repeatable fit to the tooling assembly.
• Packaging and lightweight die work: Works well for metric die sets that need economical ejection performance with predictable retention and stable alignment.

Choose this M2 + XVP variant when wear resistance and smooth actuation are priorities for high-frequency, light-duty ejection.

This product is available in M2 steel (also offered as PS4). M2 is an AISI M2 / equivalent high-speed steel grade known for strong wear resistance; in tooling applications it is typically used in a quenched and tempered condition to balance hardness and toughness for repeated contact and sliding.

• M2: High abrasion resistance with good cutting-edge durability; toughness is lower than some tougher die steels, so the XVP coating helps reduce surface wear and galling under repeated ejector cycling.
• PS4: A lower-cost alternative selected when wear demands are moderate; compared with M2, it may offer different hardness/toughness balance depending on supplied heat treatment.

The XVP coating acts as a wear-reducing surface layer, improving resistance to galling and abrasion during ejection, especially where polymer residues or high sliding contact can accelerate wear.

Select the correct punch dimensions by matching the shank diameter (D), overall length (L), and point length (L1) to your core/cavity layout and ejector train geometry. This series provides D = 6 ~ 38 mm and L ranges such as 63 ~ 100 mm, 71 ~ 100 mm, and 80 ~ 100 mm depending on configuration.

• Choose D to fit the ejector holder bore and maintain proper guidance; confirm allowable clearance based on your holder design.
• Select L1 to achieve the required penetration for blank separation: available ranges include 10 ~ 13, 10 ~ 19, 13 ~ 25, and 19 ~ 30 mm.
• Pick L so the ejector travel and retention geometry remain correct through the full stroke.
• Point tip shape is configurable (H, J, K, L, N, O, R, V, X, Y, Z)—choose based on blank edge geometry and desired ejection force profile.

Where P, W, and R dimensions control the point geometry (P = 1.4 ~ 12 mm, W = 1.4 ~ 14 mm, R = 0.2 mm), keep them consistent with the holder and punch guide specifications to avoid misalignment and uneven ejection.
