Stamping, Deep Drawing or CNC Machining? How to Choose the Process by Quantity
The four routes at a glance
| Route | Typical quantity | Tooling | Best for |
|---|---|---|---|
| CNC machining from bar | Prototypes to a few hundred | None | Thick or solid parts, threads, bores, small cosmetic batches |
| Laser cutting + bending | Prototypes to a few hundred | None | Flat and bent brackets, plates, covers |
| Stamping (single-stage or progressive die) | Production quantities (see MOQ below) | Die, 15–25 days | Repeat flat and formed parts, terminals, clips, brackets |
| Deep drawing | Production quantities (see MOQ below) | Drawing die set, 15–25 days | Seamless cups, cans, shells, housings, depth up to 400 mm |
Why quantity decides the process
A stamping or drawing die costs money and time once, then makes each part in seconds. CNC machining and laser cutting have no die cost, but every part takes machine time and, for machining, a lot of the bar ends up as chips. So the cheaper route flips at a certain quantity. Where it flips depends mainly on the material and on how complex the die has to be: a part that needs a multi-stage progressive die sits at the high end of the ranges below, a small simple part at the low end.
Typical MOQ by material
- Stainless steel (SS304, SS316, SS316L, duplex): 5–10 pcs for prototypes, 200–500 pcs for production.
- Copper and copper alloys (C11000, brass, phosphor bronze, beryllium copper): 10–50 pcs for prototypes, 500–2,000 pcs for production.
- Aluminum (1060, 3003, 5052, 6061): 50–200 pcs for prototypes, 2,000–10,000 pcs for production.
Prototype quantities are normally made without a production die, by machining, laser cutting and bending, or simple soft tooling, so the samples can be checked before the die is ordered.
Lead times for each stage
- Prototypes: typically 7–14 business days from an approved drawing.
- Dies: normally 15–25 days after the drawing is approved; the die remains your property.
- Production: typically 20–35 business days for stainless steel and 20–30 business days for aluminum and copper, after tooling is approved.
- Shipping: express courier (DHL, UPS, FedEx) for samples and small orders, air or sea freight for larger orders, added on top.
What stamping and drawing can hold
Tolerances down to ±0.01 mm are achievable on critical dimensions, confirmed part by part in the DFM review. Minimum wall thickness is about 0.05 mm for stainless steel, 0.08 mm for copper and 0.1 mm for aluminum. Draw depth goes up to 400 mm, and drawn aluminum parts can reach a depth-to-diameter ratio of up to 10:1. Carbon steel such as SPCC and Q235 galvanized steel is stamped up to 4 mm thick.
A common path: machine first, tool later
In autumn 2026 a UK customer asked for a small gold-anodized aluminum screw-top container: 10 complete units first, then up to 100. At that quantity a drawing die would never pay for itself, so the container is CNC machined from 6061 bar. If the product later sells in the thousands, the body can be redesigned for deep drawing and the die cost spread over that volume. The color and dimension questions from that project are covered in our gold anodized aluminum guide.
What to send so we can recommend a route
- 3D file (STEP or IGS) and 2D drawing (PDF, DWG or DXF) with tolerances
- Material and thickness
- Quantity per order and expected annual quantity, because the annual figure decides whether a die makes sense
- Surface finish (anodizing, passivation, electropolishing, plating, brushing and others)
- Delivery country and the date you need the parts
We reply with a quote and a DFM review within 24 hours. If a part can be made by more than one route, the review shows the alternatives and the quantity at which the price changes. An NDA can be signed before we review your drawings.
Frequently asked questions
At what quantity does a stamping die pay off?
It depends on the material and the part. As a guide, our production MOQs are about 200–500 pcs for stainless steel, 500–2,000 pcs for copper and brass and 2,000–10,000 pcs for aluminum. Below those quantities CNC machining or laser cutting plus bending is usually cheaper overall.
Can I start with machined parts and switch to stamping later?
Yes. Many projects start with machined or laser-cut parts for samples and the first small batches, and move to a stamping or drawing die once volumes grow. The part is then reviewed for stamping in the DFM review, because a few features may need small changes.
How long does a stamping or deep drawing die take, and who owns it?
Tooling normally takes 15–25 days after the drawing is approved, and the die remains the customer's property after the first production run.
How deep can you draw a part?
Draw depth goes up to 400 mm, and drawn aluminum parts can reach a depth-to-diameter ratio of up to 10:1. The achievable depth for a given part depends on material, wall thickness and diameter, and is confirmed in the DFM review.
