M2 Steel Ball Lock Ejector Punches Light Duty Tip O

These ball lock ejector punches are intended for light duty injection mold tooling where reliable locating of ejector motion is critical. The Tip O point geometry helps stabilize punch positioning during repeated blanking and ejection cycles, reducing variability in contact force and alignment.

• Automotive connector and housing inserts: Use in tool sets that require consistent blanking of small features. The M2 steel choice supports normal wear behavior for production runs, while the Tip O point maintains repeatable location at the start of each cycle.
• Consumer electronics enclosure parts: Ideal for ejector systems that must maintain stable “ball lock” engagement under cycling. Dimension availability in multiple shank diameters (D = 13–32 mm) supports matching common die/component layouts.
• General light-duty multi-cavity tooling: Suitable where controlled ejection and predictable punch behavior are needed, particularly when using metric die systems with ball lock ejector designs.

With Tip O specifically, engineers can better manage controlled ejection while preserving locating stability across production.

This series uses M2 steel as the primary option for light duty applications. M2 is an AISI M2 high-speed steel type known for good wear resistance and durability under repetitive punching and sliding contact.

• Material variants: M2 and A2 are listed as available materials. M2 is typically selected for improved wear performance in cyclic tooling, while A2 is often used when toughness and wear balance are the priority for certain duty profiles.
• Hardness / heat treatment: The provided data does not specify HRC or the exact heat-treatment state (e.g., quenched & tempered, nitrided). For design confirmation, request the heat-treatment certificate for the specific build.
• Property trade-offs: In general, harder tool steels improve edge and wear life, while sufficient toughness is needed to prevent chipping at the point geometry during cycling.

Manufacturing targets controlled fit behavior for stable ejector punch response, supporting repeatable ejecting in ball-lock systems.

To select the correct ball lock ejector punch dimensions, start by matching the shank diameter D to the corresponding bore/guide features in the ejector assembly. Available D (shank dia.) values are 13, 16, 20, 25, 32 mm.

• Point length L1: fixed range 19–30 mm. Choose L1 based on how much penetration/contact is required for your blanking and ejection sequence.
• Overall length L: fixed range 80–100 mm. Confirm clearance to avoid interference with return mechanisms and adjacent components.
• P dimension: variable range depends on configuration (e.g., 13.1–32, 16.1–38, 20.1–40, 25.1–44, 32.1–50). Select the P value that aligns with your ball-lock engagement depth and stop surfaces.
• W and R dimensions: variable W = 1.57–27.8 mm and R = 0.2–16 / 0.2–19 / 0.2–20 / 0.2–22 / 0.2–25 mm. Use these to match tip profile requirements and minimize stress concentrations.

Tolerance / fit: The dataset mentions “tight fit” behavior, so verify your ejector guide and ball-lock interface tolerances. If your cavity/core requires a specific engagement or backlash window, confirm with Axiom Molds using the exact dimension set (D, L1, L, P, W, R).
