M2 Steel Ball Lock Ejector Punches Heavy Duty

These heavy-duty ball lock ejector punches are used in injection and compression mold tooling where stable ejection force and consistent punch positioning are critical. The ball lock style tip helps the punch seat securely in the ejector system, reducing movement that can lead to uneven ejection or die damage.

• Automotive connector and bracket molds: In multi-cavity tools with frequent cycling, the secure retention and robust shank diameter range (10–40 mm) support reliable blanking and ejection in metric die sets.
• Industrial housings and appliance components: The XVP coating supports smoother cutting/working and improved surface durability during long production runs, helping maintain consistent ejection over time.
• Thermoplastic parts requiring repeatable ejector travel: Different tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow matching contact geometry to cavity/core features for stable ejection in metric toolmaking.

This series is available in M2 steel and PS4. M2 is a high-speed tool steel grade commonly specified when wear resistance and punch life are priorities in punching/blanking applications. With proper heat treatment, it can be pushed toward higher hardness for improved wear resistance, while excessive hardness can reduce toughness if design loads are high.

• M2 steel: Choose for heavy-duty service where abrasion and edge wear dominate; typically quenched and tempered to balance hardness and toughness.
• PS4: Select when you need an alternative steel option; compare hardness/impact toughness requirements to your specific loading and wear profile.

XVP coating is specified to support reduced wear at the working interface, improving surface durability during production.

Select the ejector punch dimensions by matching the punch shank and working geometry to the ejector plate and cavity/core features in your metric mold build. Start with the D (shank diameter) = 10–40 mm to fit the corresponding ejector guide/bore and to maintain stable ball-lock retention under load.

• Tip shape: Use the required contact geometry (H, J, K, L, N, O, R, V, X, Y, Z) to suit your part geometry and ejection point.
• Point length (L1): Choose from the available ranges (10–19, 13–25, 19–30, 13–25 mm options provided) to control protrusion and ejection stroke.
• Total length (L): Match to stack height and clearance; use the provided options such as 63–100, 63–125, 71–125, or 80–125 mm.
• Ball-lock interface (P and W): Confirm the P dimension (1.5–12 mm) and W dimension (1.5–14 mm) against the tool’s seat geometry for proper lock-up and positioning.

Because tolerance isn’t specified in the provided data, verify final fits against your supplier/tool standard and perform a trial fit to confirm correct seating and alignment.
