XNT DayTiN Coated Point Larger than Shank Ball Lock Ejector Punches

This ball-lock ejector punch variant is used in injection and compression die sets where stable locating during ejection is critical. The point that is larger than the shank improves engagement and helps maintain positional repeatability as the ejector system cycles.

• Automotive and appliance housings: Ideal for light-duty ejection in metric tooling where parting-line surfaces require consistent ejector contact without aggressive loading.
• Electronics enclosure dies: The larger point helps stabilize punch-to-locating features, reducing wobble during high-frequency ejection of thin-walled components.
• General die maintenance kits: The XNT DayTiN® coated surface supports reliable performance under repetitive molding cycles, making it suited for planned refurbishments and replacements.

The XNT DayTiN® coating is selected to improve wear resistance at the contact zone, supporting consistent ejector reliability in light-duty applications.

The provided product data specifies an XNT DayTiN® coating for wear-focused performance on the ejector contact area. While the underlying base steel grade and exact bulk hardness (HRC) are not listed in the input, the coating’s role is to increase surface durability under repetitive sliding/impact contact during ejection.

• Coating contribution: DayTiN-type surface engineering typically targets reduced adhesive/abrasive wear and longer punch service life versus uncoated surfaces in light-duty cycles.
• Heat treatment state: Not specified in the provided parameters; selection is generally coordinated with the punch substrate’s quench & temper or similar processing to achieve adequate toughness.

For comparison, uncoated punches rely primarily on the substrate’s through-hardness and may show faster wear at the point. Coated variants trade slightly different wear mechanisms for improved surface life, keeping ejection engagement more consistent.

Correct sizing ensures the larger point engages the mold’s ejector/locating features while the shank fits the guide/bush system. Use the D (shank diameter) to match the required guide bore and alignment constraints in your metric tooling stack.

• Choose shank diameter (D): Select one of the available values: 13, 16, 20, 25, 32 mm.
• Confirm point length (L1): Fixed 19–30 mm range (use the available option that matches your cavity/core ejection depth needs).
• Verify overall length (L): Fixed 80–100 mm to ensure adequate stroke clearance and safe guidance in the mold.
• Check tip geometry parameters: Match the Tip Shape (H, J, K, L, N, O, R, V, X, Y, Z) and the corresponding P and W ranges. These dimensions govern point footprint and clearance to surrounding steel.
• Radius (R): Select the available 0.2–16 mm (and larger listed ranges) to control contact concentration.

Because tolerances are not provided, confirm your drawing/fit requirements for slip clearance and guide alignment in the ejector system before final selection.
