Short answer: Deep drawing presses a sheet-metal blank into a die to form a seamless cup or shell; success depends on the material’s draw ratio, lubrication and punch radius, with difficult parts needing multiple redraws.
At a Glance
The Draw Ratio
The blank-to-punch diameter ratio sets how far you can draw in one hit before the wall tears; it is governed by Metal Formability Guide en Metal Springback Guide. Redraws relieve Metal Strain Hardening Guide; compare with Metal Stamping Vs Machining.
Material & Lube
Mild steel, aluminium (Aluminum Alloy Series Guide), copper and brass (Copper Brass Bronze Guide) draw well; stainless (Uitleg over roestvast staal) work-hardens and needs care. Finish via Surface Roughness Ra Guide and protect per How To Prevent Metal Rust.
QA & Supply
Find splits and ears by Metal Ndt Guide, deburr the rim (Metal Burr Deburring Guide) and document per Mill Test Certificate Guide. HXSCO supplies drawing-grade sheet and strip.
