Key takeaways
- Die cost is driven by size (circumscribing circle), die type (solid or porthole) and complexity.
- For most small and medium profiles, a die costs from a few hundred to a few thousand US dollars.
- Die cost amortises quickly: over a few tonnes of profile it often adds only cents per metre.
- Typical time to first samples is about one to three weeks; complex hollows take longer.
- Standard profiles need no die at all.
For many buyers, the extrusion die is the first number that stands out in a quote. It is also the reason extrusion is so economical: a modest one-time die cost buys a tool that can produce tonnes of profile in any length.
What drives die cost
| Driver | Effect on cost |
|---|---|
| Size (circumscribing circle) | Bigger profiles need bigger dies and bigger presses |
| Solid vs hollow | Porthole dies for hollows cost more than solid dies |
| Number of hollows | Each extra cavity adds mandrel and bridge work |
| Complexity and tongue ratios | Deep channels and fine details need stronger, more complex dies |
| Number of openings (cavities) | Multi-cavity dies make small profiles faster but cost more |
| Alloy | Harder alloys (6061, 6082) load the die more heavily |
Across the industry, dies for most small and medium profiles cost from a few hundred to a few thousand US dollars. That is typically a fraction of the cost of die-casting or injection-mold tooling, which commonly runs into tens of thousands. Your CharMax quotation always itemises die cost separately.
Amortising the die
Die cost is easy to put in perspective. Suppose a die costs USD 1,500 and you order 10,000 m of a profile weighing 0.8 kg/m — 8 tonnes of aluminum. The die adds USD 0.15 per metre, and nothing at all on repeat orders.
Lead time
For a typical profile, the sequence is:
- DFM review and die design — a few days once the drawing is final.
- Die manufacture — machining, heat treatment and nitriding of the die.
- Trial extrusion — first samples, measurement and, if needed, die correction.
Across the industry, first samples usually follow about one to three weeks after drawing approval; complex multi-hollow dies can take longer. Production follows sample approval.
Who owns the die?
When you pay for a custom die, it should be made for your profile only and never used for other customers’ orders. Dies are usually stored and maintained at the extrusion plant because they are built for that plant’s presses and die stacks. Make sure ownership, storage and maintenance terms are written into the quotation.
How to reduce die cost
- Use a standard profile from our library where one fits — no die needed.
- Simplify the section — fewer hollows, lower tongue ratios, balanced walls.
- Combine parts — one profile that serves two parts halves the die count.
- Consider a multi-cavity die for very small profiles at high volume.
- Get a DFM review before finalising the drawing — small changes often reduce die complexity.

Frequently asked questions
Is the extrusion die cost refundable?
Policies vary by supplier. Some credit part of the die cost against future orders above an agreed volume. Ask for the terms in writing with your quotation.
Why does a hollow die cost more than a solid die?
A porthole die has more components — bridges, mandrel, welding chamber — more machining and more design and correction work, so it costs more and usually takes longer to make and trial.
How many tonnes can a die produce before it wears out?
Die life varies widely with alloy, section complexity and maintenance. Regular nitriding and inspection extend it; when a die wears out it is remade from the same design.
