Product Guide
Application Scenarios+
Close space straight punches are used inside injection mold tooling and progressive die stations where punching or forming must occur with minimal clearance. In automotive connector molds, they help maintain consistent edge definition by keeping the punch aligned during repeated cycles; the close-space geometry supports stable engagement even in tight tool cavities.
For appliance and consumer electronics enclosure inserts, these punches are often employed in die sets that require clean material shearing and predictable part-to-part repeatability. The XNP coating is suited for such production because it helps reduce friction at the interface and supports reliable wear behavior as load cycles accumulate.
In medical device housing component forming, operators typically prioritize dimensional stability and surface consistency. Select the appropriate head style—AWX angled head or AXX regular head—based on access and alignment requirements to ensure the punch works correctly within the available clearance window.
Material & Process Details+
Material and heat treatment details are not specified in the provided dataset for series code 250301353991. As a result, hardness (HRC), exact steel grade equivalence, and the specific heat treatment state (e.g., quenched & tempered, nitrided) cannot be stated accurately here.
What is specified is the surface engineering approach: XNP coating. In punching applications, coatings are selected to improve sliding performance and help manage wear under repeated contact and shearing friction. This typically offers a performance trade-off: improved wear/friction behavior at the punch surface, while the underlying substrate must still provide adequate toughness for the load environment.
- XNP coating for reduced friction and improved wear behavior
- Confirm substrate grade and hardness for final tool-life predictions
Sizing & Selection Guide+
Select dimensions by matching the punch’s working length and head-to-die clearance needs to the specific cavity/core geometry in your mold or die set. For this metric series, use the fixed L (Length) range of 40–100 mm to ensure the punch projects sufficiently to complete the forming/punching stroke without bottoming or excessive stick-out.
The P dimension range of 0.8–7 mm must be compatible with the part feature thickness and the required clearance for stable guidance in close-space layouts. Because this is a close-space punch type, proper clearance directly affects alignment and cut quality.
- Choose L to cover stroke depth and support length within the die set
- Choose P to fit the feature geometry and available clearance envelope
- Head style is configurable: AWX angled head or AXX regular head—select based on access/alignment
If you have tight tolerances in your die block, verify the installed fit and guide alignment against your punch holder and die clearance stack-up.
Frequently Asked Questions
Which head style (AWX angled vs AXX regular) should I choose for a close-space die set?+
Use AWX when your tooling layout requires an angled head for better access or alignment within limited clearance. Choose AXX when you have standard straight access and prefer a regular head profile. Both are listed options for series 250301353991 under the metric close space straight punches line.
What are the available length and P dimension ranges for this metric close space punch series?+
The fixed L (Length) range is 40–100 mm. The fixed P dimension range is 0.8–7 mm. Select combinations that match your die set stroke depth and the feature geometry while maintaining close-space clearance.
How does the XNP coating help in repeated punching in tight die spaces?+
XNP coating is intended to reduce friction at the punch-work interface. In production, that friction reduction supports more consistent punching behavior and helps manage wear over repeated cycles. For best results, confirm that your substrate material and guide alignment are appropriate for the load and speed.
Can I rely on this product data to select hardness (HRC) and steel grade for wear-life calculations?+
The provided dataset does not include the underlying steel grade, hardness in HRC, or heat treatment state. Because those details are missing, you should request the substrate specification from the supplier before performing wear-life or toughness-sensitive calculations. The only explicitly stated material feature here is the XNP coating.
How do I size L and P to avoid bottoming or misalignment in a close-space punch setup?+
Set L within 40–100 mm so the punch completes the required stroke without excessive projection that risks bottoming. Match P within 0.8–7 mm to the part feature thickness and the clearance envelope needed for stable guidance. Because close-space punches are sensitive to clearance, verify your die set stack-up and installed fit.
