FAQ
Q1: Do you provide custom fastener dies based on our samples or drawings?
Yes. We offer complete customization for fastener forging dies, header dies, and thread rolling dies according to your technical drawings or prototypes.
Q2: What’s the difference between cold heading and hot heading dies?
Cold Heading Dies for fasteners are used at room temperature for small or medium-sized fasteners, while hot heading dies are suitable for large fasteners or high-strength materials that require heating.
Q3: How long is your production lead time?
Standard fastener die sets usually take 10–15 working days; complex or multi-cavity dies may take longer depending on the design.
Q4: Can you ensure consistency for large-volume production?
Yes. All dies are processed with CNC machining and inspected with CMM equipment to maintain consistent precision across batches.
Q5: What industries do your fastener dies serve?
We serve automotive, aerospace, construction, industrial machinery, power transmission, and marine industries worldwide.
