Product Guide
Application Scenarios+
Ball-lock ejector punches are used in injection molding and die-casting systems where stable part release depends on repeatable punch alignment. The ball-lock style point helps maintain lock-up position during cycling, reducing misalignment-driven wear and improving ejection consistency in compact tooling layouts.
- Die casting and small-to-medium molded housings: Choose this light-duty variant with an XNAD coating to support wear control at the punch face during frequent starts/stops.
- Automotive interior/consumer components: The alignment-stabilizing ball-lock geometry supports predictable ejection for thin features and frequent molding cycles.
- Die maintenance and forming fixtures: Coded inch tooling lengths (L = 250–450) help match standard die set conventions for efficient retrofit and replacement.
With its light-duty intent and wear-supporting coating, this configuration is suited to applications that require consistent ejection without the highest mass-load conditions of heavy-duty ejectors.
Material & Process Details+
The provided metadata specifies the XNAD coating as the key surface technology for this light-duty ball-lock ejector punch. XNAD is selected to improve wear resistance at the contact and sliding surfaces, supporting more consistent punch performance across repeated ejection cycles.
- Wear resistance vs. toughness: Coatings typically enhance surface hardness/tribology, which can reduce abrasive wear. For light-duty use, this helps maintain ejection stability while avoiding the need for extreme bulk hardness.
- Manufacturing process (functional): The typical workflow is to machine the shank and ball-lock point to the specified dimensions, then apply the XNAD coating to the working surfaces for durability.
Note: the input data does not include the underlying steel grade, hardness (HRC), or specific heat treatment condition, so those parameters cannot be confirmed from the provided specs.
Sizing & Selection Guide+
Correct sizing is critical because the ball-lock geometry must fit the ejector channel and align with the mating die components. Use the specified shank diameter D to match the clearance/guide requirements: D options are 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.875" (87), and 1.000" (100).
- Length matching (L): Select coded inch L = 250–450 to position the working point for the required stroke depth and part release timing.
- Point/ball-lock interface dimensions: Verify the tip shape code (H, J, K, L, N, O, R, V, X, Y, Z) and ensure the mating interface dimensions fall within the provided ranges for P (0.376–0.875; 0.501–1.25; 0.626–1.5; 0.751–1.5; 0.876–1.75; 1.001–1.75), W (0.062–0.867), and R (0.007–0.4375; 0.007–0.625; 0.007–0.75; 0.007–0.875).
Dimensional fit depends on your die-block machining tolerances; treat these ranges as the product’s dimension limits and confirm clearance against the ejector bore/seat drawing to prevent binding during cycling.
Frequently Asked Questions
Which shank diameter D values are available for these light-duty ball-lock ejector punches?+
The shank diameter D is available in six inch options: 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.875" (87), and 1.000" (100).
Select the D size that matches the ejector guide bore/seat requirements for your standard die set.
How do I choose the correct coded length L for proper ejection stroke and timing?+
Use the coded inch L range of 250–450 to set the working point position relative to the parting line and stripper travel.
Match L to your cavity/core layout so the ball-lock punch engages and releases without bottoming or excessive overtravel.
What tip shape codes are supported, and how do they affect compatibility with the die seat?+
This series supports tip shape codes: H, J, K, L, N, O, R, V, X, Y, Z.
Compatibility depends on the mating seat geometry and the associated dimensions; confirm the tip code and interface dimensions such as P, W, and R fall within the ranges for the selected configuration.
What is the role of the XNAD coating in this ejector punch variant?+
The variant is specified as (XNAD coating), intended to improve wear control for consistent punch performance during repeated ejection.
Coating selection is especially relevant for light-duty cycles where abrasive/tribological wear at the punch working surfaces can degrade alignment over time.
Do the provided specs include heat treatment or steel grade for hardness (HRC)?+
No. The provided input data does not specify the underlying steel grade, heat treatment state (e.g., quenched & tempered, nitrided), or hardness in HRC.
For material verification, rely on the supplier’s material/processing documentation for the exact punch stock and coating system used on the selected series.
