M2 Steel Ball Lock Regular Ejector Punches XNM Coating X-Shaped Tip

These ball-lock regular ejector punches are used in injection molding tooling where stable, repeatable part or runner blank ejection is required after molding. The ball-lock geometry helps keep the punch properly positioned during the short, high-cycle strokes typical of light-duty systems.

• Progressive die / light-duty forming lines: The X-shaped tip supports controlled penetration for consistent ejection of small blanks, reducing variation across successive press cycles.
• Thin-wall insert or trimmed component production: The XNM-coated surface improves wear behavior at the punch tip, helping maintain ejection force uniformity over longer runs.
• Metric tooling requiring quick die-set repeatability: With M2 steel and defined point length and overall length options, the punch can be matched to cavity depth while preserving accurate lock-up.

For scenarios with frequent cycles and moderate wear, this variant is suited because the combination of M2 steel and XNM coating targets long-term wear resistance while the X-shaped tip promotes dependable ejector action.

This product uses M2 steel, a high-speed steel commonly referenced as the AISI M2 equivalent for tooling applications requiring good wear resistance. In general, M2 is typically supplied in a hardened and tempered state for a balance of hardness and toughness suitable for repeated mechanical impact at the punch tip.

• Wear resistance: M2’s alloying enables strong abrasion and edge retention during repeated ejector strokes.
• Toughness trade-off: Higher hardness improves wear, but can reduce resistance to severe shock; proper dimensional selection and alignment help avoid overstress at the point.
• Coating effect (XNM): The XNM coating is intended to further reduce tip wear and maintain performance in longer production runs.

An alternative material option listed for this family is PS4. If you are comparing materials, confirm your target cycle count and expected abrasive conditions—M2 is typically chosen when wear resistance is the priority, while alternative steels may be selected to tune toughness, cost, or processing.

Selection should start by matching the punch shank diameter (D) and overall length (L) to your ejector plate and guide constraints, then setting the point length (L1) to achieve the required penetration into the cavity without bottoming.

• Shank diameter D (mm): choose from 6 ~ 32 to match the housing/guide bore for the ball-lock regular design.
• Point length L1 (mm): options include 10 ~ 13, 10 ~ 19, or 13 ~ 25 depending on required effective stroke.
• Overall length L (mm): options include 63 ~ 100 or 71 ~ 100 for compatibility with ejector assembly stack-up.

Also verify the tip geometry and dimensions: P (1.4 ~ 10), W (1.4 ~ 12.5), and R (0.2 ~ 0.2) affect penetration profile and resulting blank ejection behavior. The family lists these dimensions as variable selections, so treat the selected dimensions as fixed for the configured part; confirm clearance to die and cavity surfaces since tolerance data is not provided in the input.
