Ball Lock Regular Ejector Punches XCN Coating

Ball-lock regular ejector punches are used in injection mold tooling and similar press systems where repeatable ejection and reliable punch retention are required. The ball-lock geometry helps maintain consistent operation over high cycle counts by improving retention during handling and tool maintenance.

• Automotive and appliance part molds: Suited for housings and structural components that require stable ejection and smooth material flow under heavy-duty production demands. The wear-supporting XCN coating helps maintain performance in demanding forming or stamping-like cycles.
• Progressive die and precision press fixtures: Ideal when punch-to-holder retention consistency affects dimensional stability. The regular shank and point length ranges (D: 10–40 mm; L: 63–125 mm) support common metric tooling stacks.
• High-mix, short-run production: Used where tool change frequency increases the risk of retention drift. This variant’s ball-lock design and wear-oriented coating support dependable punch performance across repeated cycles.

These punches are offered in M2 or PS4 material options, allowing selection based on wear versus toughness needs. M2 (commonly associated with AISI M2 / high-speed steel) is selected where higher wear resistance and dimensional stability under intermittent load are important. PS4 is typically chosen for applications requiring a different balance of hardness and toughness for robust punch wear behavior.

• Coating state: The XCN coating is applied to increase surface wear resistance for demanding workloads.
• Heat treatment: The provided configuration is based on standard punch steels; final hardness depends on the chosen grade and supplier heat-treatment practice, with the XCN layer contributing to reduced adhesive/abrasive wear.
• Trade-off: Higher hardness grades generally improve wear resistance but can reduce toughness under shock; selection between M2 and PS4 helps manage that balance for your ejection forces.

To select the correct ball-lock regular ejector punch, match the shank diameter, overall length, and point geometry to your core/ejector setup and clearance conditions. Start with the required D (shank dia.) in the range 10–40 mm, then choose the L1 (point length) from 10–19 mm, 13–25 mm, or 19–30 mm to ensure the point protrusion meets ejection depth.

• Overall length: Select L from 63–125 mm, 71–125 mm, or 80–125 mm based on your ejector plate stack-up and available stroke space.
• Tip shape: Choose the required tip shape (H, J, K, L, N, O, R, V, X, Y, Z) to fit the part geometry and avoid point interference.
• Ball-lock and critical dimensions: Ensure the P (1.5–12 mm) and W (1.5–14 mm) dimensions are compatible with the holder/retention pocket geometry. The R value is specified at 0.2 mm, which affects point edge contact.
• Tolerance/fit: Because retention depends on holder matching, confirm that the chosen D and ball-lock-related dimensions align with your punch guide bore and retention groove tolerances.
