M2 Steel Ball Lock Ejector Punches Light Duty

These light-duty ball lock ejector punches are used in injection mold and die tooling where reliable blank or part ejection is needed without extreme wear loading. The ball-lock retaining geometry helps maintain stable retention during repeated press cycles, improving consistency when retracting and ejecting small or medium components.

• Metric connector and bracket molds: select this style when the ejection force is moderate and you need repeatable punch-to-cavity contact using the controlled point geometry and ball-lock retention.
• Electronics housings and covers: suited for predictable ejection in light duty tool builds, especially when small ejector strokes demand stable punch behavior and secure part release.
• General workshop press and die inserts: compatible with shank diameters from 6–38 mm and multiple point lengths, supporting standardized, metric tooling layouts; optional XNT DayTiN® coating can be requested to enhance wear performance.

M2 steel is selected for this light-duty ejector application because it provides a good balance of wear resistance and toughness for punch contacts and repeated ejection cycles. Where available for the same geometry, PS4 can be considered as an alternative material option; however, your selection should follow the expected contact pressure, cycle count, and wear environment.

• Heat treatment (typical for M2 use): M2 ejector components are commonly supplied in a hardened condition achieved by quenching and tempering (final hardness governed by the supplier’s processing for tool steel performance).
• Hardness & wear vs. toughness: higher hardness improves abrasive and adhesive wear resistance at the point, while too much hardness can reduce impact toughness; choose based on whether ejection is smooth or subject to shock loading.
• Coating option: XNT DayTiN® may be requested to further support surface wear performance.

For exact final hardness (HRC) and treatment state, confirm the processing certificate associated with your chosen material and coating request.

Correct selection starts with matching the ejector shank diameter and overall length to your mold’s ejector system and cavity/core spacing. This series supports D (shank dia.) = 6–38 mm, so verify your guide-bushing/receiver bore and the available wall thickness around the ejector channel before choosing the final size.

• Point geometry: choose the required Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z) to match the part surface and to control contact area and ejection reliability.
• Point length (L1): select from 10–13, 10–19, 13–25, or 19–30 mm depending on how deep the punch must reach into the cavity to transfer force.
• Total length (L): options are 63–100, 71–100, or 80–100 mm; ensure sufficient protrusion for ejection travel while maintaining clearance to avoid interference during return.
• Fit considerations: confirm dimensional compatibility with the ejector hole and ball-lock retaining features; if you require tight alignment for reduced side load, maintain the specified tolerance and verify the P and W dimensions (P = 1.4–12 mm, W = 1.4–14 mm).

R is specified at 0.2 mm in this dataset—ensure your mating geometry and clearance accommodate the specified radius.
