Metric Light Duty Ball Lock Ejector Punches

These metric light-duty ball lock ejector punches are used in punch-and-die injection tooling where repeatable ejection and secure retention are required. The ball-lock interface helps maintain stable punch seating across cycles, reducing variability in ejection force and timing.

• Automotive and general press tooling inserts: Suitable for die sets that eject small to medium parts reliably, especially when consistent punch-to-die positioning is critical.
• Consumer electronics housings and small brackets: Used in cavity/core systems where light-duty ejection supports clean part release while protecting surrounding features.
• Multi-cavity or maintenance-friendly assemblies: The ball-lock point design supports dependable engagement during operation; the optional XNA coating is well-suited when smoother punch travel and reduced wear are desired in production environments.

Because this variant is explicitly designed for light-duty applications and precise punch seating in metric assemblies, it fits well where stable ejection repeatability matters more than heavy shock loads.

The provided configuration specifies functionality and geometry for metric light-duty ball lock ejector punches, but it does not include a steel grade, heat-treatment condition, or target hardness (HRC) in the available data. For that reason, specific statements about tempering, nitriding, quenching, or HRC values cannot be confirmed for this exact part variant.

What is supported by the specifications is the optional surface treatment: XNA coating. In tooling terms, an appropriate coating is typically selected to improve sliding behavior and help manage wear during high-cycle ejection.

• XNA coating (optional): Chosen to support smoother operation and reduced wear versus uncoated surfaces under light-duty ejection conditions.
• Unspecified base material: Please provide the steel grade (or request the datasheet) if you need confirmed hardness (HRC) and heat-treatment details for qualification.

Select the ball lock ejector punch by matching the shank diameter and overall length to the guide and ejector layout in your die set, then verify the point geometry for correct engagement.

• Shank diameter (D): Choose from 13, 16, 20, 25, 32 mm to match the tooling insert/guide bore requirements.
• Overall length (L): Available in 80–100 mm, select the length that reaches the required ejection stroke while avoiding bottoming in the housing.
• Point length (L1): Fixed at 19–30 mm; use this to ensure the ball-lock point engages properly with the receiving die area.
• P and W dimensions: These vary by D (e.g., P 13.1–32, W 1.57–27.8)—confirm they align with your cavity/core clearances and any restraint features.
• Tip radius (R): R is variable in ranges such as 0.2–16, 0.2–19, 0.2–20, 0.2–22, and 0.2–25; select the closest option to your part-contact profile.

If your design depends on tight fit for seating, request the drawing to confirm tolerances for the selected D and tip shape.
