M2 Steel Ball Lock Regular Ejector Punches - Light Duty

Ball lock regular ejector punches are used in injection molds and tool-and-die assemblies where controlled ejection and long cycle life are critical. The light-duty configuration is well suited for precision die sets, such as small automotive connector and latch component molds, where consistent part release depends on stable punch retention and repeatable stroke behavior.

In medical device housing and insert molding, the selectable tip geometry (X/R/K/O/H/L/J/N/V/Z) allows you to match the contacting surface profile to delicate features while maintaining reliable ball-lock retention for smooth ejection.

For consumer electronics and appliance components, the M2 steel option provides wear-focused performance for production runs that experience repeated contact and sliding, helping maintain dimensional stability of the ejector working end.

• Ball-lock format supports strong retention for consistent ejection
• M2 steel variant is suited to wear resistance in repetitive tool cycles
• Tip selection supports varied workpiece contact profiles

This line is offered in M2 steel (and an alternative PS4 option per configuration). M2 is a high-speed steel commonly selected for ejector punches when wear resistance and tooling durability are prioritized under repeated contact.

• Typical state: supplied as a heat-treated tooling steel suitable for cutting-tool performance; final hardness depends on the selected variant and supplier heat treatment conditions.
• Hardness & trade-offs: expect a balance of high wear resistance with adequate toughness; higher hardness improves abrasion resistance but can reduce impact toughness if overstressed.

For applications with heavy surface abrasion, M2 is generally preferred for maintaining the punch point geometry over long production. If your process emphasizes different wear/impact balance, compare the available PS4 material configuration against the expected contact pressure and ejection shock.

Use the specified size ranges to match the punch to your mold core/cavity ejector layout. Start with the shank diameter D: available from 6 to 38 mm. Select a diameter that matches the ejector guide bore and the retention features of the mold tooling design to avoid binding or excessive clearance.

Next, choose the point length (L1) based on the required penetration depth and the clearance to adjacent mold steel. L1 is available in the grouped ranges of 10–13, 10–19, 13–25, or 19–30 mm.

Then verify overall length L for your stack-up height: options include 63–100, 71–100, or 80–100 mm. Confirm the working-profile dimensions P (1.4–12 mm) and W (1.4–14 mm), and the specified R (0.2 mm) at the profile edge. If you select different tip shapes (H/J/K/L/N/O/R/V/X/Y/Z), recheck contact geometry so the punch interfaces the part without overloading the ejector.

• Match D to guide bore/retention requirements (6–38 mm)
• Match L1 to required engagement depth (10–13 to 19–30 mm)
• Match L to mold stack-up height (63–100, 71–100, 80–100 mm)
