Product Guide

🏭Application Scenarios+

This light-duty ball-lock ejector punch is used in injection mold tooling and die sets where controlled, repeatable ejection is required. The ball-lock geometry provides secure retention during cycling and helps maintain alignment between the punch and the mating component, reducing the risk of mis-travel.

  • Automotive and consumer connector molds: Suitable for ejection of small molded parts from thin gate geometries, where stable retention and a consistent point profile support reliable part release.
  • Appliance and housing inserts: Works well in multi-part tools and secondary operations that benefit from the positive engagement of the ball-lock style during ejector stroke.
  • General die-making in inch tool environments: The inch light-duty format and precision tip options support fit with common tool-building workflows.

Choose this variant when you need secure retention plus the ability to match tip and point length codes to your cavity/core design for dependable ejection.

🔧Material & Process Details+

The punches are offered in three hardened steel options: M2, A2, and PS4. M2 (high-speed steel, AISI M2 equivalent) is selected when you want high wear resistance for repeated ejection cycles and abrasive contact. A2 (AISI A2 tool steel equivalent) provides a balanced combination of wear resistance and toughness for general light-duty ejector use.

  • M2: Typically heat-treated to a harder condition for wear-focused performance; best suited to long-run tools where tip wear is a concern.
  • A2: More toughness trade-off versus maximum hardness; helps maintain edge stability under impact-like loading.
  • PS4: A dedicated hardened option aimed at reliable performance in die and mold applications.

Depending on supplier heat-treatment state, these grades are generally supplied in a hardened condition appropriate for punching/ejector service. Select the grade based on the balance you need between tip wear resistance and toughness for your ejection duty.

📐Sizing & Selection Guide+

To select the correct dimensions, match your ejector travel and contact length needs to the available inch point length and shank dimensions. The shank diameter D is available from 25 ~ 100 in (per the provided parameter set). Tip geometry is selectable by H, J, K, L, N, O, R, V, X, Y, Z to align with your die face or part-release interface.

  • Choose the point/length code: Point length 200 ~ 400, 200 ~ 500, 200 ~ 600, and 225 ~ 600 are available depending on the coded configuration (including variants for B&L and C ranges).
  • Fixed length option: A fixed configuration is listed for 250 ~ 600 (coded inch), which simplifies selection when your tool requires a specific length window.
  • Match P and W: The P dimension is 0.05 ~ 0.75 in and W is 0.05 ~ 0.437 in; these must fit your mating ball-lock pocket and clearance.

Because several dimensions are provided as ranges by code, confirm the required length window for your cavity/core spacing and ensure your mating pocket design accounts for the ejector’s engagement features (ball-lock fit).

Frequently Asked Questions

Which tip shape code (H, J, K, L, N, O, R, V, X, Y, Z) should I use for a specific ejector contact profile?+

Tip shape is selected using the provided code set (H, J, K, L, N, O, R, V, X, Y, Z). Use the code that matches your required contact geometry at the die face so the punch engages consistently during ejection. If you have constraints on corner radius or contact area, choose the closest tip profile code and then verify point length and shank diameter compatibility.

How do I choose between M2, A2, and PS4 for ejector punch wear and toughness?+

The material is offered as M2, A2, or PS4. M2 is selected for higher wear resistance in long-run service, while A2 provides a more balanced wear/toughness trade-off for general light-duty use. PS4 is another hardened option intended for dependable die and mold performance. Match the grade to your expected abrasion and loading conditions at the ejector tip.

What point length options are available, and how do I match them to cavity/core spacing?+

Point length is provided in inch coded ranges such as 200 ~ 400, 200 ~ 500, 200 ~ 600, and 225 ~ 600, with separate coded configurations for B&L and C ranges. There is also a fixed length window listed as 250 ~ 600. Select the code whose length window fits your required ejector reach from the plate to the part-release interface, considering your mold stack-up.

How do D (shank diameter) and engagement dimensions P and W affect ball-lock retention?+

The shank diameter D is available in the range 25 ~ 100 in (per the supplied parameters). The engagement-related dimensions P (0.05 ~ 0.75 in) and W (0.05 ~ 0.437 in) must be compatible with the mating ball-lock pocket to ensure secure retention during operation. Verify that your pocket geometry and clearances are designed for the specific coded configuration of these dimensions.

Which Jektole group (J2, J3, J4, J6, J9) is compatible with my tool design?+

The product lists Jektole group options as J2, J3, J4, J6, J9. Compatibility depends on how your tool’s ejector system defines group-specific geometry and interfaces. When selecting a group, also confirm the corresponding point length configuration (including B&L and C coded ranges) so the overall stack and engagement remain correct.
