Ball Lock Ejector Punches Light Duty Inch XAN DayTAN™ Coating

Ball-lock retention ejector punches are used in injection mold tooling where stable punch location directly impacts part release quality. In automotive connector and housing molds, the ball-lock mechanism helps maintain consistent positioning through high-cycle operation, supporting uniform ejection and reducing misalignment-related scuffing.

• Die casting and molding: improves repeatable ejection stability for cast cores/slides with frequent cycling.
• Precision forming: supports controlled stroke consistency when light-duty inch tooling is selected for standard die builds.
• XAN DayTAN™ coating use case: suitable when wear at the punch/guide interface is a concern during production runs.

Selecting this variant with the DayTAN™ coating is especially beneficial for molds experiencing regular ejection cycles, where surface durability contributes to longer service intervals.

These light-duty inch ball-lock ejector punches are available in M2 and PS4. M2 is a high-performance tool steel typically selected for strong wear resistance under intermittent cutting and abrasion; it balances toughness with good hardness after heat treatment. PS4 is offered as an alternative steel option when your application prioritizes a different toughness/wear balance and available processing route.

• XAN DayTAN™ coating: adds additional surface wear resistance at the ejector/punch interface for frequent cycling.
• Hardness & trade-offs: higher hardness improves abrasion resistance but can reduce impact toughness if the heat treatment is pushed toward maximum hardness. For punch tools, manufacturers generally temper to protect chipping risk.
• Heat treatment state: the listed steels are intended for hardened tool-steel service; the exact hardness and temper specifics depend on the selected material grade and punching geometry.

For best life, match steel and coating to your expected cycle count, ejection loads, and guide/punch surface conditions.

To select the correct punch dimensions, start with the shank diameter D (in) and the overall point length L coding required by your die layout. This series supports D = 25 ~ 100 in and L options in the coded-inch ranges: 200 ~ 400, 200 ~ 500, 200 ~ 600, or 225 ~ 600. Point length B & L also varies by coded range (e.g., 225 ~ 400, 225 ~ 500, 225 ~ 600), and one fixed option is specified as 250 ~ 600.

• Match stroke requirements: choose the length range that provides full ejection travel without bottoming.
• Interface clearance: respect your guide clearance strategy so the ball-lock retains alignment without binding.
• Dimension selection: the P (0.05 ~ 0.75 in) and W (0.05 ~ 0.437 in) dimensions determine the functional geometry; use the exact coded values that correspond to your tooling standard.
• Fit considerations: select the appropriate tip shape (H, J, K, L, N, O, R, V, X, Y, Z) for the cavity/core contact surface to avoid uneven wear.

When multiple coded length options exist, prioritize the range that matches your cavity/core thickness stack-up and return clearance.
