Metric Straight Ejector Punches (XNAD Coating)

These metric straight ejector punches are used in injection and forming tooling where stable, straight part release is critical. In production die sets, the straight-guided geometry helps maintain alignment during ejection, reducing the risk of scuffing, drag marks, or uneven release on thin or precision features.

• Precision die casting and punch applications: The XNAD surface coating is intended to improve wear resistance under repeated contact cycles, supporting consistent ejection force and longer service life.
• Punch-and-form tooling for formed components: Use when the part requires controlled removal from the die cavity with minimal lateral movement.
• Metric tooling compatibility: The fixed metric dimensions support easier fit into standard die bases and ejector systems designed around metric layouts.

With length options in the 50–90 mm range and P dimension coverage from 5–16 mm, this variant suits mold designs needing reliable straight guidance and abrasion-resistant surfaces during high-cycle operation.

The provided specification focuses on the geometry and XNAD coating performance characteristics rather than a specific base steel grade. For engineers selecting ejector tooling, the key material-related advantage is that the DAYTON XNAD coating is used to improve wear resistance against abrasion from repeated ejection contact.

• Wear resistance: Enhanced surface durability helps resist polishing and edge rounding over high cycle counts.
• Toughness/strength trade-off: In ejector applications, base steel toughness typically controls resistance to bending and chipping, while the coating primarily targets surface wear; balance depends on the underlying punch steel.
• Heat treatment state: Not specified in the provided data; verify the underlying punch steel hardness and any surface treatment details (e.g., pre-hardened vs. quenched & tempered) when finalizing the tool build.

If alternative materials are required for higher shock loads, request the base steel grade and hardness (HRC) for direct comparison to coating-driven wear targets.

Select the ejector punch dimensions to match both the ejector travel envelope and the die set geometry. This series provides fixed length L = 50–90 mm and fixed P dimension = 5–16 mm, so you can choose the version that fits your die thickness stack and ejection stroke requirements.

• Match length L: Ensure the selected L accommodates the die open/close position and ejector stroke without bottoming or excessive protrusion beyond guide limits.
• Match P dimension: Use the available P range (5–16 mm) to align with the mating pocket/shoulder features in your ejector layout, maintaining proper support for straight guidance.
• Tolerance and fit: Confirm clearance and alignment requirements between punch and guide components; because dimensions are fixed per variant, ensure your drawings use the same metric reference and allowable tolerances for assembly fit.

For multi-cavity tools, verify each station’s die thickness and ejector travel before standardizing on a single L and P option.
