Ball Lock Regular Ejector Punches - Light Duty (Inch)

Ball-lock regular ejector punches are used in inch punch-and-die injection tooling where reliable part release is required under frequent cycling. The ball-lock retention style helps maintain alignment and punch stability, reducing the risk of punch walk during repeated ejector strokes.

• Automotive connector and bracket molds: Suitable for light-duty cavities where consistent ejection geometry is needed; selectable tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) allow designers to match contact area and part features.
• Consumer electronics housings: The regular ejector format supports stable ejection in die sets using inch-based layouts, enabling efficient component replacement during maintenance.
• General precision parts with long runs: The XCDP coating option is well suited for improved wear resistance, supporting durability over extended production.

Choose the light-duty inch variant when you need dependable ejection performance with configurable tip design while staying compatible with standard inch mold component practices.

This series is offered in M2 or PS4 material options, supporting different balances of wear resistance and toughness for ejector service. M2 is a high-performance tool steel commonly selected where cutting-edge performance and abrasion resistance are valued.

• M2: Typically air/appropriate quench and temper for tool steel service; aim hardness in the commonly used high-speed/stamping range (often around the mid-60s HRC for cutting-tool performance). Expect high wear resistance, with toughness that can be tuned by tempering.
• PS4 (comparison): Chosen when a different property balance is preferred for punch/die wear life and stability; hardness and toughness characteristics depend on the supplied heat treatment state for this grade.

Additionally, an XCDP coating option can be used to enhance surface wear resistance, which helps maintain ejection tip geometry during long production runs.

Select dimensions by matching the ejector punch to the cavity/core interface and the available mold space in your inch tooling design. Start with the shank diameter D (25 ~ 100 in) to ensure proper guidance within the ejector plate and related bearing surfaces.

• Choose tip shape: Select from H, J, K, L, N, O, R, V, X, Y, Z to align the contact geometry with the part under ejection.
• Match point length and overall length: Available point length & length (coded inch) ranges include 200–500, 200–600, 200–700, 225–700 and additional variants like 225–500/600/700 or 250–700 depending on the coded configuration.
• Use P and W only when your fixture requires fine control: P is 0.04–0.75 in and W is 0.04–0.437 in, which correspond to defined geometry features for the specified design.

Confirm the coded length option (e.g., 200–700 vs. 225–700) against core depth so the punch reaches the required ejection travel without interference. When integrating into guided systems, verify fit with your plate/bores using standard toolmaker clearances; tolerance values are dependent on the mold component drawing for your tooling system.
