Ball Lock Regular Ejector Punches Light Duty X Tip

Where it’s used: These ball-lock ejector punches are designed for metric progressive and stamping die sets where repeatable part release is critical, especially at short cycle times. The compact ball-lock retention geometry helps keep the punch stable through repeated press strokes, reducing punch movement that can lead to inconsistent ejection.

Scenario 1 – Automotive and industrial housings: For die tooling producing small plastic components (e.g., connectors and lightweight enclosures), the X tip supports controlled pushing and clean release, helping protect delicate features during ejection.

Scenario 2 – Electronics insert and clip parts: In tooling that forms or overmolds small metal-plated inserts, reliable retention improves repeatability under frequent cycling, while the light-duty X tip geometry helps manage contact and reduce drag.

Scenario 3 – General metric die maintenance: When engineers need a consistent metric ejector punch for routine die builds, the material options (M2 or PS4) align with wear requirements typical of production environments.

• X tip geometry: controlled pushing and release behavior
• Ball-lock retention: stable operation during press cycles

Available grades: This punch is offered in M2 or PS4 materials to match different wear and toughness needs for light-duty ejection applications.

• M2 steel: typically selected for higher wear resistance and consistent cutting/tooling performance in abrasive or high-cycle conditions. It is commonly supplied in a hardened condition for durability, with quenched and tempered practices used to balance hardness and toughness.
• PS4 grade: selected as an alternative material option when wear resistance and steady performance are required for tooling environments aligned with metric die builds.

Hardness and trade-offs: Hardened tool steels provide better wear resistance, but increasing hardness can reduce toughness. For light-duty ejection, the design’s stable ball-lock retention helps offset toughness concerns by limiting punch movement under load.

Note: Exact HRC, quench temperature, and temper cycle depend on the selected material option and supplier heat-treatment specification.

How to size it: Start by matching the shank diameter (D) to the corresponding guide/holder bore in your die set. Select an available D range: 6 ~ 38 mm so the punch seats correctly while maintaining designed clearance.

Point geometry selection: Choose the Tip Shape = X variant, then align the point length and overall length to your cavity/core depth requirements. The available L1 (Point Length) options are 10–13, 10–19, 13–25, or 19–30 mm, and the overall L options include 63–100, 71–100, 80–100, or 63–100 (per catalog grouping).

• P dimension: 1.4 ~ 12 mm (tip-to-side geometry constraint)
• W dimension: 1.4 ~ 14 mm (contact/clearance planning)
• R dimension: 0.2 mm (small-radius feature)

Tolerance/fit: Use your die-holder bore tolerance and surface finish requirements to confirm clearance and prevent binding. If your cavity/core depth varies across stations, prioritize the L1 range that guarantees full part push without excessive over-travel.
