Best for
Cans, sinks, pots, battery cans and pressure housings in volume.
Watch for
Wrinkling and tearing risk; needs blank-holder control and sometimes several draws.

Design tips
A few general pointers for Deep Drawing. The full, part-specific DFM list is in the dossier.
Draw ratio too aggressive.Add a draw stage or relax depth.
Sharp corner radii.Increase radii.
Cost
What it costs
Cups, cans, enclosures at high volume; expensive multi-stage tooling, cheap per part once running.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for your part at your volume, in your currency, are in the dossier.

What does Deep Drawing cost per part?
It depends on size, tolerance and volume. As a rough ballpark it starts around $0.94 to 1.6 per part at low volume and falls with quantity. The dossier gives should-cost at your exact volume and currency. Model estimates, not quotes.
What tolerance can Deep Drawing hold?
Typically about +/-0.2 mm, tighter with extra finishing operations at higher cost.
What materials suit Deep Drawing?
Common choices are Deep-draw steel (DC04/DC06) (High formability); Aluminium 1100/3003 (Soft, draws well); Stainless 304 DDQ (Corrosion).
