Ball Lock Ejector Punches Heavy Duty XCN Coating

These heavy-duty ball-lock ejector punches are designed for precision ejection in injection mold tooling where repeated actuation demands stable retention. The ball-lock geometry helps keep the punch securely seated during ejection cycles, reducing the risk of movement that can translate into flash or surface defects.

• Metric automotive and industrial connector molds: Used in die inserts to eject sprue gates or parting-line features consistently under long production runs. The XCN coating supports durable performance against wear from abrasive residues and repeated contact.
• Appliance and housings with deep ribs: Suitable for ejecting parts with tall features where ejection stability is critical. The punch’s selectable tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow tuning the contact profile to the workpiece surface.
• Multi-cavity tools with frequent indexing: Beneficial when tool shut height and ejection timing must remain repeatable. The heavy-duty variant in wear-resistant M2 options helps maintain dimensional stability over time.

This line is offered in M2 steel and PS4, enabling a choice between wear-oriented performance and alternative steel behavior for different production profiles. M2 is a high-speed steel known for strong wear resistance when used in cutting-tool-like conditions; it is well suited for ejector punches that experience sliding contact and repeated impact during ejection.

• M2 steel option: Designed to resist wear and maintain edge/contact integrity under repeated cycles.
• PS4 option: Provided as an alternate material selection for differing toughness/wear requirements across tool builders’ standard practices.

For coating performance, an XCN coating is used to improve surface durability. While the dataset does not specify an exact hardness or heat-treatment condition (e.g., quenched & tempered vs. nitrided), the material and coating combination targets reduced wear and longer service life in die tooling applications.

To select the correct ball-lock ejector punch, match the shank diameter (D) and length (L) to your ejector system and the die insert pocket geometry. The shank diameter is available in 10 ~ 40 mm, so choose the punch size that corresponds to the guiding bushing or drilled guide features in your mold base.

• Choose point length (L1): Available ranges include 10–19, 13–25, 19–30, and 13–25. Use L1 to control how far the contact portion reaches into the part.
• Choose overall length (L): Provided in 63–100, 63–125, 71–125, and 80–125. Ensure the stroke clearance and shut-height engagement remain within your ejector travel.
• Verify contact dimensions: Tip geometry uses P (1.5–12 mm) and W (1.5–14 mm), and the provided R dimension is 0.2. Select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to match your ejecting contact profile.

All listed dimensions should be treated as configurable product variants; confirm fit in your tool by checking pocket clearance and guidance alignment for stable retention during ejection.
