Ball Lock Ejector Punches - Light Duty Metric

Light-duty metric ball-lock ejector punches are used to support repeatable part release in injection molding and related tooling where ejector force is moderate. The ball-lock geometry helps maintain stable engagement and consistent ejection without relying solely on friction between the part and cavity.

• Progressive die and precision stamping tooling: The larger point relative to the shank improves ball-lock engagement, which is beneficial for consistent stripping across repeated stations.
• Light-duty die applications and housings: Use the XNP-coated variant when you expect frequent cycles and want improved wear resistance at the contact zone to help maintain ejection reliability.
• Multi-cavity inserts with tight assembly guidance: Metric punch geometry supports accurate alignment and repeatable seating of the ball-lock feature during mold assembly and operation.

Choose the available tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) and shank diameters (D = 13–32 mm) to match your cavity/core interface and ejector path requirements.

This product variant is specified by its XNP coating for improved surface wear behavior under repeated light-duty cycling. While the input data does not list the base steel grade or heat treatment set (e.g., quench & temper, nitriding), the coating is the key material feature driving durability at the tip and ball-lock contact surfaces.

• XNP coating benefits: Enhanced wear resistance at the region subjected to frequent contact during part release.
• Trade-offs: Coatings can slightly change surface hardness and friction characteristics; selecting the correct tip shape and ball-lock fit is important to preserve engagement consistency.

For applications with higher abrasion or impact, engineers typically compare alternative steels or coated options with documented base hardness and heat treatment. For this item, rely on XNP-coated wear performance plus correct dimensional matching to achieve stable ball locking.

Select dimensions to ensure the ball-lock point seats correctly while maintaining guidance through the ejector plate and bushings. Start with the required shank diameter D (mm): 13, 16, 20, 25, 32 to match the tooling bore and any supporting components.

• Point length L1: Fixed at 19–30 mm. Choose within this range based on how far the point must extend to contact the part release feature.
• Total punch length L: Fixed at 80–100 mm. Confirm stroke stack-up so the punch does not bottom out or lose engagement.
• Geometry matching: Use the correct tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and select compatible P, W, and R values from the available ranges to fit your ball-lock recess/profile.
• Fit considerations: Since P, W, and R vary by configuration (e.g., P = 13.1–32, W = 1.57–27.8, R = 0.2–25), verify that the chosen configuration aligns with your ejector receiver geometry for repeatable locking.

The provided ranges are configuration-dependent; match the exact configuration’s dimensions rather than mixing values from different tip arrangements.
