Product Guide
Application Scenarios+
These metric straight ejector punches are used in injection mold tooling where reliable ejection and smooth, repeatable punch travel are critical. A common application is automotive connector and sensor housings, where high-cycle operation demands stable ejector movement and consistent part release after each shot.
They are also well suited for consumer electronics enclosures and appliance components that experience fine tolerances and repeated ejection events. The straight punch geometry supports straightforward alignment in core/ejector layouts, helping maintain predictable ejection force and stroke without excessive side loading.
In addition, they fit general-purpose punching and ejection stations within metal-to-mold inserts or modular tooling, benefiting from the XN DayTride® coating to reduce wear under abrasive, punching-related contact. The 50–90 mm length range and P dimension 5–16 mm design allow engineers to match stroke needs and assembly fit within typical metric die structures.
Material & Process Details+
The provided product specifications focus on dimensional fit and the XN DayTride® coating, while no specific base steel grade (e.g., SKD61, 1.2344, AISI M2) or measured hardness (HRC) is stated in the data. As a result, the heat-treatment state and exact hardness values cannot be confirmed from the current specification set.
From a functionality standpoint, the XN DayTride® coating is selected to improve surface durability during punching and repeated ejector cycling. In wear-dominated applications, coatings typically enhance abrasion resistance and can extend service intervals; however, the exact balance between wear resistance and toughness depends on the underlying steel grade and its quench-and-temper or nitriding condition (not provided here).

- Steel grade / HRC / heat treatment: not specified in the provided data
Sizing & Selection Guide+
Select the punch length L first, then confirm the engagement/assembly geometry using the P dimension. This series is offered with fixed L = 50–90 mm and P = 5–16 mm, so dimension selection should be driven by your ejector stroke requirement and the available guide/ejector plate space.
To size for your core cavity:
- Match L (50–90 mm) to the required protrusion and the distance from the ejector plate to the part-contact face, ensuring adequate travel without bottoming.
- Match P (5–16 mm) to your punch support and alignment features (e.g., interface to the ejector system or load-bearing area) so the punch can transmit force without binding.
- Tolerance/fit: use your mold’s standard clearance and guidance requirements for straight punches; since tolerance values are not provided here, confirm fit during trial assembly.
Because the dimensions are specified as fixed ranges, choose the closest available L and P combination that meets stroke and contact requirements for your tooling design.
Frequently Asked Questions
What are the available length and P-dimension ranges for this ejector punch series?+
This series is specified with a fixed L (Length) of 50–90 mm and a fixed P dimension of 5–16 mm. Choose L based on required ejector protrusion and safe stroke, and choose P to match your punch engagement/support geometry.
How does the XN DayTride® coating help in punching and ejector wear conditions?+
The XN DayTride® coating is designed to enhance wear resistance during punching-related contact and repeated ejector cycling. For high-cycle tools, this coating support helps maintain more stable punch movement and can support longer service intervals under abrasive wear mechanisms.
Is this suitable for straight ejection layouts in metric mold tooling?+
Yes. The product is specifically described as metric straight ejector punches intended for straight ejection punch layouts in metric dies. The straight geometry is appropriate for core/ejector systems where alignment and controlled travel are required.
What steel grade and hardness (HRC) should I assume when selecting this punch?+
The provided data confirms coating presence (XN DayTride®) and dimensional ranges (L 50–90 mm, P 5–16 mm), but it does not list the underlying steel grade, heat-treatment state, or hardness (HRC). For hardness-based life calculations, request the steel grade and test hardness documentation for the exact part number in your configuration.
How do I ensure correct fit and avoid binding when installing these straight punches?+
Use P (5–16 mm) to match your support/alignment interfaces and select L (50–90 mm) to control protrusion and stroke clearance. Since tolerance values are not provided in the current specifications, verify clearance and alignment during trial assembly to prevent side loading and binding in guide or support areas.
