Ball Lock Ejector Punches - Light Duty, Inch, XAN DayTAN™ Coating

Ball lock ejector punches are used in injection mold tooling where reliable ejection actuation and repeatable retention are required. In light-duty inch progressive or transfer die systems, the ball-lock mechanism benefits from this variant’s larger tip versus shank geometry, which supports stable locking during repeated cycling.

For automotive and appliance component molds that run frequent production cycles, the XAN DayTAN™ coating helps improve ejection smoothness while supporting wear and corrosion resistance on the punch surfaces. This helps reduce sticking risk when ejector motion is partially lubricity-dependent.

In general engineering packaging and housings with modest mold pressures, engineers can select specific inch shank diameters to match the die block opening and guide conditions, keeping ejector alignment consistent across the stroke.

• Designed for light-duty inch tooling and ball-lock ejection systems
• Point larger than shank supports dependable ball-lock retention
• XAN DayTAN™ coating supports smoother ejection and surface protection

The provided product data specifies a XAN DayTAN™ coating intended to enhance surface protection for light-duty ejector service. While the underlying steel grade and heat-treatment targets (e.g., quench & temper, nitriding) are not listed in the metadata, the coating is selected to address wear and corrosion resistance at the ejector working surfaces.

In ejector punch applications, engineers typically balance hardness for abrasion resistance against toughness for shock resistance during actuation. For ball-lock punches, consistent surface performance is important because sticking or micro-rust can impair motion and retention.

• XAN DayTAN™ coating: designed for improved ejection smoothness and corrosion/wear support
• Hardness (HRC), specific heat treatment, and base steel grade: not provided in the current specification set
• If alternate steel grades/coatings are required, confirm heat-treatment state and target hardness with the supplier before final tooling sign-off

Select the ejector punch dimensions by matching the shank diameter (D), overall length (L), and working geometry to the die assembly opening and stroke requirements. This light-duty inch series provides D options of 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), and 1.0000" (100).

Choose L (coded inch) from 250 ～ 450 to ensure sufficient engagement length for safe ejection travel and stable ball-lock operation within the die stack.

• Match D to the corresponding guide/bore diameter for clearance control
• Select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) based on part ejector contact needs
• Use P (0.376 ～ 0.875 / 0.501 ～ 1.25 / 0.626 ～ 1.5 / 0.751 ～ 1.5 / 0.876 ～ 1.75) and W (0.062 ～ 0.867) as geometry-dictated parameters for your die cut and contact profile
• Confirm R radius (0.007 ～ 0.4375 / 0.007 ～ 0.625 / 0.007 ～ 0.75 / 0.007 ～ 0.875) to avoid interference in the cavity/core area

Tip and shank differences are intentional; avoid modifying cavity/core clearances that could affect ball-lock retention.
