Ball Lock Regular Ejector Punches - Heavy Duty X-Shaped Tip

This heavy-duty ejector punch is used in die tooling where reliable ball-lock ejection is critical to consistent part release. The X-shaped tip is engineered to maintain stable contact with the mating features during ejection, helping improve repeatability when cycle rates and tonnage are high.

• Automotive and appliance components: In progressive or transfer dies, the ball-lock geometry supports controlled ejection force, while the X-shaped point helps reduce sticking-related variance during high-volume runs.
• Metric die sets for precision housings: For die cavities requiring uniform opening and part separation, the stable tip contact provided by this variant supports repeatable ejection across production batches.
• Die tryout and PPAP-style validation: When evaluating tool behavior before ramp-up, the punch’s heavy-duty ball-lock design supports dependable performance under trial conditions, reducing the risk of inconsistent part release.

Choose this configuration when your tooling demands stable engagement at the punch point and consistent ejection results under production load.

These ejector punches are available in M2 or PS4 steel construction, supporting reliable wear resistance for ball-lock ejection in die tooling.

• M2: A high-speed steel option typically selected for strong wear resistance in high-cycle applications. The usual trade-off is that toughness and edge impact resistance can be more sensitive to heat-treatment balance than lower-alloy steels.
• PS4: A tool steel variant chosen for durable performance in tooling environments; it is commonly specified when robust service life and stable ejection behavior are required.

In both cases, performance depends on the supplied heat treatment state (e.g., quenched and tempered to achieve the target hardness). For engineers, hardness in the HRC range is the key indicator for balancing wear resistance (higher HRC) against toughness (lower risk of chipping at somewhat reduced hardness). Select based on expected contact pressure, cycle count, and any risk of brittle edge behavior.

To select the correct punch size, match the shank diameter D and overall dimensions to your ejector system and die layout. Available D range is 10 ~ 40 mm, so choose the diameter that fits your guide/receiver features with the required clearance for smooth movement.

• Point length L1: select from 10 ~ 19, 13 ~ 25, or 19 ~ 30 mm depending on how deep the X-tip must engage for ball-lock ejection.
• Overall length L: choose from 63 ~ 125 mm sets (including 71 ~ 125 and 80 ~ 125 ranges) to ensure the punch reaches the correct stroke position without bottoming.
• Tip geometry dimensions: P is 1.5 ~ 12 mm, W is 1.5 ~ 14 mm, with R = 0.2 mm fixed per the provided spec range.

When integrating into cavities/cores, confirm that the tip length (L1) aligns with the ball-lock engagement depth while the overall length (L) supports the full ejection stroke. Verify fit/tolerance needs in your press standard—especially around guide diameter D—to prevent binding and maintain repeatable contact at the tip.
