Ball Lock Ejector Punches Light Duty Inch XNAD Coating

Ball-lock ejector punches are used in injection molding tooling where reliable ejection repeatability matters, especially in die sets that also perform die casting or progressive stamping. The ball-lock tip geometry helps stabilize the punch during travel, reducing relative shifting that can lead to uneven part release.

• Die casting tooling: suited for light-duty cavity sets that need consistent ejection without excessive wear. The XNAD coating supports smoother long-run contact with mating components.
• Automotive and appliance stamping: supports repeatable punch-to-location alignment in ejector stations, helping maintain consistent part drop across cycles.
• Light-duty multi-cavity molds: ideal when the ejector system benefits from controlled seating and predictable positioning under modest load.

The Inch light-duty configuration and coded point length options let you match travel and fit to your ejector layout for stable ejection behavior.

These light-duty ball-lock ejector punches are offered in M2 and PS4. M2 is a high-speed steel grade commonly selected for its balance of hardness and wear resistance in sliding contact; it generally tolerates repeated cycling when properly heat treated for ejector service. PS4 is used where a lower-cost alloy with good performance for punching/ejection applications is preferred.

• M2: typically chosen to maximize wear resistance under frequent contact.
• PS4: typically chosen for acceptable toughness and practical durability in light-duty tooling.

Both options are paired with the XNAD coating, which is intended to reduce surface wear and support smoother operation. Exact hardness (HRC) and the heat-treatment state (e.g., quenched & tempered vs. nitrided) are not specified in the provided data, so they should be confirmed for your selected configuration.

Select the ejector punch by matching the shank diameter D (in) and the coded point length L (and related point-length variants) to your mold core/cavity ejection requirements. For D, choose from 25 ~ 100 (in range as listed) based on your ejector guide system and allowable clearance.

• Tip shape: pick H, J, K, L, N, O, R, V, X, Y, or Z to match the required ball-lock engagement profile.
• Point length options: choose coded length ranges such as 200–400, 200–500, 200–600, or 225–600 (plus B/L and C/B/L and D/B/L coded ranges like 225–400, 250–600, etc.) to achieve correct protrusion and stroke clearance.
• Contact dimensions: use P = 0.05 ~ 0.75 and W = 0.05 ~ 0.437 within the provided ranges for the intended locking/fit geometry; R = 0.007 is fixed per the data.

For best fit, confirm that your mating die block or retainer pocket supports the selected ball-lock geometry for stable seating under ejection forces; the provided data gives dimension ranges, but tolerances are not specified, so verify drawing-level fits in your design review.
