Point Larger Than Shank Ball Lock Ejector Punches - Heavy Duty, Metric

Ball-lock ejector punches with a point larger than the shank are used in injection mold tooling where repeatable ejection force and stable lock-up are required. The enlarged point geometry improves guidance and maintains consistent ball engagement throughout cycling, helping reduce position drift in high-throughput production.

• Automotive and appliance components (metric progressive/insert tooling): Select the appropriate shank diameter (D = 13, 16, 20, 25, 32, 40 mm) and point shape to keep ejection alignment stable under heavy duty cycles.
• Large die-set ejector systems: The fixed point length range (L1 = 19–30 mm) supports reliable contact geometry, while the overall length (L = 80–100 mm) allows integration into deeper ejector assemblies.
• Multi-up production where wear control matters: The XAN DayTAN™ coating is specified for improved wear resistance during repetitive ejection, supporting longer service life with sustained dimensional stability.

The provided metadata specifies this heavy duty metric ball-lock punch family and its XAN DayTAN™ coating, but it does not list a specific steel grade, hardness (HRC), or heat treatment condition. Therefore, the coating-related wear and surface durability are the only material/process aspects that can be stated reliably from the input data.

• Coating: XAN DayTAN™ is identified as the wear-supporting surface treatment intended for repetitive production, helping maintain punch geometry over time.
• Heat treatment: Not specified in the input; heat treatment state (e.g., quenched & tempered, nitrided) cannot be confirmed.
• Trade-off: Without hardness/toughness data, the relative balance between wear resistance and toughness for this specific variant cannot be quantified from the provided information.

To select the correct punch size, start by matching the shank diameter to your ejector guide and lock-ball interface using D (shank dia.) = 13, 16, 20, 25, 32, or 40 mm. Next, confirm the overall length requirement: L = 80–100 mm for the assembled punch travel and housing clearance.

• Point geometry: Choose the tip shape from H, J, K, L, N, O, R, V, X, Y, Z to match the mating ejector face/contact conditions. The point length is fixed at L1 = 19–30 mm.
• Match cavity/core interface: Verify the P and W dimensions fall within the available ranges (P = 13.1–32, 16.1–38, 20.1–40, 25.1–44, 32.1–50, 40.1–56; W = 1.57–34.73) for proper seating and contact.
• R corner detail: Use the appropriate R option (0.2–16, 0.2–19, 0.2–20, 0.2–22, 0.2–25, 0.2–28) to avoid interference and achieve consistent lock-ball engagement.

Tolerance/fit: The input provides dimensional ranges but not tolerance values; final fit should be validated against your mold design drawings and the specific ball-lock interface standard used for the Jektole group (J6, J9, J12).
