Metric Point Larger than Shank Ejector Ball Lock Punches - Light Duty (XNA Coating)

These metric ball-lock punch points are used in light-duty injection molding and press tooling where consistent point retention and reliable ejection timing are required. The larger-than-shank tip geometry helps stabilize engagement in the lock area, reducing the risk of point movement during repeated cycles.

• Automotive connector and sensor housings: Ideal for die inserts and precision forming steps that need repeatable ejection of small molded features. The point length range (L1: 19–30 mm) supports tailoring to cavity/core geometry while maintaining secure lock-up.
• Consumer appliance components: Suitable for punch & die sets handling short-to-medium production runs where wear resistance is needed but extreme high-load performance is not the primary driver.
• General medical device housings (non-critical exterior features): Works well for forming operations requiring dependable engagement in standard metric tool builds; the XNA coating supports improved wear over time.

XNA coating enhances surface wear performance, making this variant a practical choice for long production with light-duty tooling constraints.

The series specifies an XNA coating for the point surface, which is intended to improve wear performance during repeated lock/unlock cycling in light-duty tooling. While the base steel grade and explicit heat-treatment target are not provided in the available data, the coating is used to extend usable life by reducing point wear and frictional degradation at the contact surfaces.

• Wear resistance vs. toughness trade-off: Coatings like XNA generally increase wear resistance; however, they do not replace the need for adequate substrate toughness in impact-prone or misalignment-sensitive tooling.
• Manufacturing process (typical): Tool steel blanks are machined to the required point geometry and shank diameter, then finished and coated for improved surface durability.

For applications requiring high hardness substrate performance (e.g., severe abrasion), confirm the underlying steel grade and heat-treatment state with your moldmaker before finalizing.

To select the correct dimensions, start by matching the shank diameter (D) to your mating ball-lock insert/punch pocket in the tool. Available shank diameters are 13, 16, 20, 25, and 32 mm, and the point geometry must be compatible with the corresponding lock bore and retention features.

• Point length (L1): Choose within 19–30 mm to ensure the point reaches the required forming depth without bottoming or excessive protrusion.
• Overall length (L): Select from 80–100 mm to fit the press spacing and guide setup.
• Geometry options: Tip shapes are available as H, J, K, L, N, O, R, V, X, Y, Z. The provided P and W ranges (P: 13.1–50 mm depending on D; W: 1.57–27.8 mm) and R radii (R: 0.2–25 mm) must align with your cavity corner radii and functional engagement profile.

Verify dimensional tolerance/fit requirements against your tool’s specified ball-lock interface; this product’s dimensions are selectable by range, not fixed to a single size, so confirm the mating feature tolerances in your drawing package.
