M2 Steel Ball Lock Regular Ejector Punches - Heavy Duty

Ball-lock regular ejector punches are used to provide dependable part ejection in precision injection molding and press-based tooling where the ejector must stay positively aligned under repeated cycles. The ball-lock tip geometry helps maintain retention and consistent ejection positioning, which is critical when ejecting thin-wall or tightly fitting components.

• Automotive connector and housing molds: Use this M2-based, heavy-duty variant with an XVP coating to improve surface durability during high-cycle ejection of inserts or housings where scuffing and tip wear can degrade repeatability.
• Electronics and appliance housings: In molds requiring stable forming across runs, the precision ground point geometry supports repeatable ejection height and reduces the risk of uneven part release.
• Metric die sets for heavy-duty stamping/punching: This configuration is suited for metric tooling, helping deliver reliable ejection while resisting abrasion from particulate-filled compounds or aggressive gate flash patterns.

Selecting the M2 steel + XVP option is particularly advantageous when you expect sustained wear and need consistent ejection performance over long production runs.

This ejector punch is offered in M2 steel or PS4. M2 is a high-speed steel grade commonly selected for wear resistance and long service life under repeated contact and sliding, which is valuable for ball-lock tip designs that experience frequent micro-movement during ejection.

The heavy-duty configuration includes an XVP coating to enhance surface durability and reduce wear at the working tip. Compared with PS4, M2 is typically chosen when the application prioritizes hardness and abrasion resistance at the ejector face; PS4 is an alternate option when a different balance of toughness and cost is preferred.

• Heat treatment state: Heat-treated for hardened tool performance prior to finishing/point grinding (exact hardness is not provided in the supplied data).
• Wear vs. toughness: Higher surface hardness improves resistance to abrasive wear, while toughness is managed through the specific quenched-and-tempered condition used by the supplier.

Use M2 for demanding, high-cycle ejection where tip wear and maintaining forming repeatability are primary concerns.

Choose the ejector punch geometry by matching the shank and working tip dimensions to your mold cavity/core layout. The supplied ranges include D (shank diameter) from 10–40 mm, and L (overall length) in sets such as 63–125 mm, 71–125 mm, and 80–125 mm. Confirm the required L1 (point length) to ensure the ball-lock tip protrudes correctly into the ejection zone: available ranges are 10–19, 13–25, or 19–30 mm.

• Tip shape: Select from H, J, K, L, N, O, R, V, X, Y, Z based on part-release contact area and clearance.
• Contact dimensions: Match P (1.5–12 mm) and W (1.5–14 mm) to your receiver/part geometry to avoid interference.
• Ball-lock fit: The R dimension is provided as 0.2 mm; keep the mating interface consistent to preserve retention and alignment.

Where exact tolerance requirements are critical, confirm final clearance/fit with the mold designer before ordering, since tolerance data is not included in the supplied specifications.
