Ball Lock Ejector Punches - Light Duty, Inch

These light-duty ball lock ejector punches are used in injection mold toolbases where controlled ejection is required but cavity pressures and loads are moderate. The ball-lock geometry helps maintain stable positioning during part release, reducing the risk of uneven stripper contact or sticky ejector movement.

• Consumer electronics and housings: Ideal for ejecting small plastic components from fine-detail cores, where repeatable engagement and smooth stroke help prevent surface marking. The CRN coating supports longer service intervals under light abrasive contamination.
• Automotive interior brackets/connectors (light duty): Suited for punch-and-die assemblies that need consistent part release cycles without heavy wear rates. Inch-coded point length options let you match ejector travel to the mold’s shut height and stack-up.
• General-purpose fixtures and small medical/device housings: Useful when a stable, tool-friendly ejector system is needed for dependable trimming or release operations. Multiple tip shapes (H–Z) support fit to specific pocket and lead-in geometries.

This variant is available in M2 and PS4 material options, supporting different performance priorities in light-duty ejection tooling. M2 is a high-speed steel commonly selected for balanced wear resistance and toughness; it is typically hardened for improved abrasion resistance in sliding punch applications. PS4 is used for die/punch applications where stable performance is desired under moderate loads, with trade-offs in maximum wear capability versus harder high-performance grades.

• Wear resistance: CRN coating (as specified for this series) enhances surface durability against fretting and mild abrasion during repeated cycles.
• Toughness trade-off: Higher-hardness tool steels generally improve wear life but can be more sensitive to edge damage if misaligned; proper fit and alignment are important for long term reliability.
• Heat treatment state: Select hardened, quenched-and-tempered tool-steel condition to achieve consistent hardness before coating and final grinding.

Selection starts with matching the ejector punch shank and point length to the mold cavity/core stack-up and required ejection travel. For shank diameter D, choose from 25–100 in based on the guide/bushing bore and the load-bearing needs of the ejector system. Confirm the point length to achieve the correct stroke: standard options are 200–400, 200–500, 200–600, or 225–600 (coded inch).

• Point length “B & L” (coded inch): options include 225–400, 225–500, 225–600 and also 225–500, 225–600 variants depending on the C group; a fixed range is also listed as 250–600.
• Fit considerations: Verify that the shank diameter and guide alignment meet your press-fit or sliding-fit requirements; small form variations can affect ball-lock engagement stability.
• Configurable geometry: Tip shape can be H, J, K, L, N, O, R, V, X, Y, or Z to match lead-in and cavity clearing profiles.
