M2 Steel Ball Lock Ejector Punches (Heavy Duty, Metric)

These heavy duty ball lock ejector punches are used in injection mold tooling where consistent part release and repeatable locating are required over high cycle counts. The X-shaped tip geometry supports controlled positioning and predictable ejection behavior, reducing the risk of uneven lift or drag marks on the molded part.

• Automotive and appliance components: Ideal for multi-cavity molds using metric tooling, especially where stable ejection under varying part wall thickness helps maintain dimensional consistency.
• Precision housings and covers: The ball lock format helps hold tight assembly-length fit in the ejector train, supporting stable engagement and reducing motion play that can affect part-to-part repeatability.
• Progressive die and forming systems: The DayTride®-coated, M2-based construction improves wear resistance under repeated contact with workpieces and ejector surfaces.

Choose the M2 steel variant when you need a balance of wear resistance and toughness for heavy duty, metric applications with frequent ejection cycles.

This series is offered in M2 (high-speed steel) and PS4 as indicated by the material options. M2 is widely used in ejector punch components for its strong wear resistance and good performance under repeated sliding/impact conditions, making it suitable for heavy duty metric tooling.

The meta description specifies a DayTride® coating, which is intended to improve surface wear resistance and maintain stable ejection performance across production runs. For heat treatment, these ejector punches are typically supplied in a hardened state appropriate for tooling use, supporting practical hardness for long-life operation.

• Hardness & trade-off: Higher hardness increases abrasive wear resistance but can reduce toughness if pushed too far; the M2 grade selection targets a workable balance for repeated ejector action.
• Wear vs. toughness: Coating contributes to reduced wear, while the steel base provides the toughness needed to tolerate cycling.

PS4 is an alternative material option within the same punch family when your application emphasizes different wear/strength priorities.

Select dimensions by matching the ejector train geometry and cavity/core layout. Start with the shank diameter (D) in the required range: 10 ~ 40 mm. Then choose the overall L (length) that fits the available stack-up for the ejector stroke and support spacing (available ranges include 63 ~ 100, 63 ~ 125, 71 ~ 125, and 80 ~ 125).

• Point length (L1): Ensure the contact/active tip travel is correct by selecting among 10 ~ 19, 13 ~ 25, or 19 ~ 30 mm ranges.
• Tip geometry: Pick the required tip shape from the available set (H, J, K, L, N, O, R, V, X, Y, Z); the X-shaped tip variant is commonly used where controlled locating and release are needed.
• Profile dimensions: Verify P (1.5 ~ 12 mm), W (1.5 ~ 14 mm), and R (0.2 mm) for compatibility with your guide and part contact features.

Dimensions here are provided as spec ranges; confirm your drawing-level fit requirements against the ejector system tolerances used in your mold design.
