Inch Slug Control Ball Lock Die Buttons with XN DayTride Coa

Slug control ball lock die buttons are used in injection mold tool builds where the die needs consistent alignment and repeatable engagement during high-cycle production. This design is well-suited for automotive connector and insert molds, where tight positional repeatability helps maintain stable gate and cavity relationships despite thermal expansion.

The XN DayTride® coated surface variant is also advantageous for consumer electronics housing molds with frequent cycling, because reduced friction can improve return smoothness and help manage wear on the locating interface.

For medical device and labware mold assemblies, ball-lock action supports controlled slug movement and dependable alignment when the tooling requires predictable engagement after ejector actuation. Select the appropriate tip shape (H/J/K/N/O/R/V/X/Y/Z) to match your die engagement geometry and ensure the slug control behavior is consistent with your cavity/core layout.

• Use in die sets requiring controlled slug movement and stable repeatability
• Coating supports reduced friction and wear in cycling conditions
• Tip shape selection enables fit to existing engagement features

Material and heat-treatment details are not specified in the provided data. What is specified is the slug control material thickness, which ranges from 0.001 to 0.4 in, and the side clearance per 1 to 25%. These parameters directly influence stiffness, wear behavior at the locating interface, and the trade-off between compliance (to accommodate tolerance stack-up) and positional rigidity.

The XN DayTride® coating is the key surface technology for this variant. In high-cycle molds, a low-friction coating helps reduce sliding/impact wear on the die button locating surfaces, supporting quicker, more consistent return after each cycle.

• Thickness (0.001–0.4 in): thicker slug control generally increases rigidity but may reduce tolerance accommodation
• Clearance per side (1–25%): higher clearance improves compliance, lower clearance improves positional tightness

If you need a specific steel grade, hardness target (HRC), or nitriding/quench-and-temper requirement, confirm these details with your tooling material specification because they are not contained in the current product metadata.

Use the fixed and variable dimensions to match the ball lock die button to your mold’s die engagement features. This series uses a fixed length L = 118 (coded inch), so selection focuses on outer diameter and engagement geometry.

Choose D (outer diameter) within 50–175 in based on available pocket space and the required locating contact area. Select a compatible tip shape from H, J, K, N, O, R, V, X, Y, Z to align with your core/cavity engagement design.

For the slug control behavior, set the P and W dimensions within 0.048–1.0351 in (both are variable in this range) to match your internal engagement or clearance geometry. The slug control material thickness is 0.001–0.4 in, and the clearance per side is 1–25%—use these to manage tolerance stack-up while maintaining repeatable die engagement.

• Match D and tip shape to physical space and mating geometry
• Use P/W and clearance % to balance tight alignment vs. compliance
• L is fixed (coded inch 118), so do not change length during selection
