Product Guide
Application Scenarios+
These heavy-duty ball lock ejector punches are used in injection mold tooling where ejection reliability and point stability directly affect cycle consistency and dimensional control.
- Automotive and industrial part ejection: In multi-cavity or progressive applications, the ball-lock point helps resist point movement under repeated strokes, supporting stable fit in punch-and-die sets during high cadence production.
- Robust inch-series tooling: The inch-based variants are suitable for standard American mold component architectures, making it easier to integrate into existing ejector layouts while maintaining controlled positioning during ejection.
- High-wear molding inserts: The XCD coating variant is well-suited for environments where abrasion and sliding at the point area reduce service life; it helps extend wear performance while maintaining consistent ejection behavior.
Select the applicable tip shape and group based on your ejector geometry to match retention requirements and stroke-to-station alignment.
Material & Process Details+
The provided product data specifies an XCD coating for abrasion resistance, intended to improve sliding/wear performance at the punch point during repeated ejection cycles. However, the input does not list a specific steel grade, base material heat treatment state, or target hardness (HRC), so those values cannot be stated reliably.
- Coating function (XCD): Designed to improve wear resistance where material loss and surface abrasion drive downtime.
- Wear vs. toughness consideration: Coatings can enhance surface durability, but real performance depends on the underlying steel toughness and the contact mechanics in your mold cavity/core.
- Material comparison: No alternative steel/coating grades are included in the supplied specifications, so a numeric comparison cannot be made.
For hardness, base steel grade, and heat treatment, confirm the exact item drawing from your series code before final qualification.
Sizing & Selection Guide+
To select the correct ball lock ejector punch dimensions, start from the mold’s ejector system design: cavity/core thickness, stripper plate spacing, and the mating bore profile required for controlled positioning.
- Shank diameter (D): Choose D in the range 37 ~ 125 in to match the designated guide/fit size in your ejector layout.
- Length (L, coded inch): Select L from the available coded ranges 250 ~ 450 (or 275 ~ 450). Ensure the total projected stroke and stop-to-contact geometry provide clearance for the ejector travel.
- Point/geometry: Match Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z) and the Jektole group (J4, J6, J9, J12) to the ball-lock point interface used in your punch-and-die set.
- Cross-sectional features: Verify P (0.376 ~ 1.251 in), W (0.062 ~ 1.083 in), and R (0.007 ~ 1 in, depending on the variant) align with the mating component tolerances.
Because tolerance/fit data is not provided in the input, rely on the manufacturer’s technical drawing for clearance values and locking retention checks.
Frequently Asked Questions
Which tip shapes and Jektole groups are compatible with a ball-lock ejector punch interface?+
This heavy-duty inch series is offered in multiple Tip Shapes (H, J, K, L, N, O, R, V, X, Y, Z) and Jektole groups (J4, J6, J9, J12). Use the tip shape and group that match the mating ball-lock pocket/point interface in your punch-and-die set. Confirm compatibility against the ejector tooling drawing because the ball-lock geometry is critical for retention and repeatability.
How do I choose the correct shank diameter (D) range for my ejector guiding system?+
The shank diameter D is specified as 37 ~ 125 in for this series. Select D based on the bore/guide diameter in your ejector layout to achieve the intended controlled fit. Since tolerance values are not included in the provided data, validate final clearances using the item’s technical drawing before machining the mating parts.
What length options (L coded inch) should I verify against stripper plate spacing and stroke stops?+
Available L (coded inch) ranges are 250 ~ 450 and 275 ~ 450 (with a 250 ~ 450 variant also shown). Check that the selected length provides the required projected ejection travel while maintaining safe clearance to the cavity/core and ensuring positive stop control. For precise integration, compare the coded length against your detailed mold stack-up dimensions.
How do P, W, and R dimensions affect fitting to the punch-and-die set in this series?+
This product family includes variable geometric parameters: P 0.376 ~ 1.251 in, W 0.062 ~ 1.083 in, and R 0.007 ~ 1 in (range depends on the variant). These dimensions influence the contact profile and how the punch point interfaces with mating components. Match P/W/R to your specified interface geometry, then verify fit using the manufacturer’s tolerances since they are not provided in the input data.
What does the XCD coating change for wear performance, and what material/heat treatment should I expect?+
The data provided states this variant includes XCD coating to improve abrasion resistance and extend wear life under repeated ejection. However, the input does not specify the base steel grade, hardness (HRC), or the heat treatment state. To finalize performance expectations (wear vs. toughness), confirm the steel grade and heat treatment from the official item drawing or qualification report.
