Product Guide
Application Scenarios+
Metric close-space straight punches are used in injection and stamping tooling where the working clearance is extremely limited and the punch must maintain consistent cutting and ejection behavior. The straight, close-space geometry helps manage material flow and supports controlled shearing when building precision mold inserts with tight die spacing.
- Automotive and appliance stampings: select the regular head or angled head variant to match tool access constraints while the reduced-clearance design improves cut quality at higher production rates.
- Consumer electronics housings and brackets: the punch’s selection range for L = 40–100 mm supports alignment through deeper tool stacks without compromising operational stability.
- Die protection in long runs: the XN DayTride® coating is suited to reduce friction and wear, helping stabilize performance and extend tooling life in repetitive production conditions.
Choose the head type (AWX angled head or AXX regular head) to best suit your die layout and feed/spring load geometry.
Material & Process Details+
The product is specified as a metric close-space straight punch with an XN DayTride® coating, which is intended to enhance wear resistance and reduce friction against die components during cutting and ejection cycles. While the input data does not define the underlying steel grade or its heat treatment state (e.g., quench & temper, nitriding), the coating performance is the key differentiator for durability in abrasive and high-cycle operations.
- Wear resistance vs. toughness: coated surfaces generally improve abrasion resistance at the working interface; however, overall toughness still depends on the punch substrate and its heat treatment.
- Friction reduction: the coating helps lower coefficient of friction during repeated contact, supporting more stable cutting conditions across long runs.
If your design requires a specific substrate hardness (HRC) for shock loading, request the detailed steel/heat-treatment specification for this series_code to ensure full compatibility with your cutting loads.
Sizing & Selection Guide+
Correct selection is primarily governed by the punch L length and the P dimension (0.8–7 mm), which must match your tool stack-up and clearance design. Start by mapping the required engagement depth in your punch holder and die block, then choose a length within L = 40–100 mm to ensure the working tip remains properly positioned through the die.
- Match cavity/core geometry: verify the close-space clearance design of your die set so the punch’s straight geometry can perform controlled cutting without interference.
- Set engagement and support: select L to maintain adequate guidance and minimize bending under load, especially in deeper tool stacks.
- Choose the correct profile: pick AWX (angled head) or AXX (regular head) based on your die layout and space for retainer/punch adapter components.
Because tolerances are not provided in the input data, confirm fit through your supplier’s drawing/spec sheet and align with your press tonnage and guiding system requirements.
Frequently Asked Questions
How do I choose between the AWX (angled head) and AXX (regular head) versions for a close-space die?+
Select AWX when your tooling layout needs an angled head profile for clearance around holders, ejector systems, or access to the punch tip. Use AXX when a regular head supports straightforward alignment and standard holder interfaces. Both variants are intended for the same metric close-space straight punch function, but the head style impacts how the punch seats and clears surrounding components.
What length range (L) should I use to match my die stack and punch engagement depth?+
This series supports L = 40–100 mm. Choose the length that positions the working end correctly through your die set while keeping adequate support in the punch guide to reduce bending. If your tool stack varies across assemblies, validate the chosen L against your punch holder depth and spring/stroke arrangement.
How does the P dimension (0.8–7 mm) affect cutting performance in tight clearances?+
The provided P dimension = 0.8–7 mm is a key geometry parameter for close-space applications. Use your die designer drawings to confirm how this dimension relates to the clearance, cutting land, or guiding/engagement features in your die set. An incorrect P can lead to poor cut quality or unwanted contact in limited clearance dies.
What benefits does the XN DayTride® coating provide for long production runs?+
The XN DayTride® coating is intended to improve wear resistance and reduce friction during cutting and ejection cycles. This helps maintain more stable operating conditions over extended production, especially in abrasive or high-cycle stamping operations. Coating performance supports tool life, but substrate hardness and heat treatment still govern toughness under shock loads.
Do I need a specific substrate hardness (HRC) for die protection in high-load trimming?+
The input data does not specify the punch steel grade or its heat treatment hardness (HRC). Since coated punches improve the working interface but toughness depends on the substrate, confirm the steel grade and heat-treatment details for series_code 250301353946 when designing for high shock or heavy trimming loads. Request the official material/heat-treatment specification to ensure the substrate hardness aligns with your forming forces.
