Ball Lock Ejector Punches Heavy Duty Inch

These heavy-duty ball lock ejector punches are used in injection mold tooling where reliable part removal and stable retention are required, especially during high-cycle production. The ball lock mechanism helps maintain consistent blank holding and repeatable ejection, reducing the risk of mis-seating that can lead to part damage or short shots.

• Automotive and appliance components: When ejector travel must be dependable under abrasive or debris-prone conditions, the heavy-duty construction supports consistent performance across long runs.
• Industrial housings and covers: Use the inch-coded tip geometry options to match cavity/core layouts and ensure controlled release without excessive wear on punch faces.
• High-wear tooling environments: The CRN coating package is suited for applications where contact surfaces see recurring sliding/impact, helping limit wear and abrasive damage.

With multiple tip shapes (H, J, K, L, N, O, R, V, X, Y, Z), this variant can be configured for varied part geometries and ejection requirements.

This series is available in M2 and PS4 material options, enabling selection based on wear and toughness needs. M2 (high-speed steel) is typically chosen for its strong wear resistance and hardness retention under repeated ejection conditions; the trade-off is that it requires correct heat treatment to balance toughness and avoid brittleness at the working surface.

• M2: Commonly used in tooling where edge retention and wear resistance are critical; best suited when CRN-coated surfaces will experience frequent contact.
• PS4: Used when a different balance of toughness and wear performance is desired for specific tooling duty cycles.
• Coating: The CRN coating package is specified to help reduce tool wear and abrasive damage at the contact region.

For precise hardness (HRC) and heat-treatment state, confirm the exact supplied material certificate for the chosen option (M2 vs. PS4), as these values are not provided in the supplied dataset.

Select ejector punch size by matching the punch shank diameter and functional lengths to your mold cavity/core and ejection stroke design. Start with D (shank diameter) from 37 ~ 125 in and choose the tip shape code that fits your part-release geometry.

• Standard point length / L: Options include 250 ~ 500, 250 ~ 600, 275 ~ 600, and 300 ~ 600 (coded inch).
• B, C, and D point length ranges: These are also configurable within 250 ~ 500, 250 ~ 600, 275 ~ 600, and 300 ~ 600 (with one listed option for D as 250 ~ 600, 275 ~ 600, 300 ~ 600).
• P and W features: P = 0.062 ~ 1 in, W = 0.062 ~ 0.5 in, and R = 0.007 ~ 0.007 in.

Confirm engagement length so the punch fully contacts the ejectable area without bottoming. If your system uses tight ejector bore fits, verify selected shank diameter clearance/tolerance against your ejector guide specs; tolerances are not included in the provided dataset.
