Sam Zhang is a Process Engineer at Aunov with 14 years in metal deep drawing and drawing-based forming. He leads process development and tool/die commissioning across product formability analysis, draw-process design, CAE simulation, and trial-run tuning. His work covers cold drawing, hot drawing, multi-stage drawing and ironing, tooling for drawing/forming/trimming/flanging/calibrating, FLC-based springback compensation and wrinkle prediction, sheet material selection, press-line process planning, lubrication, and defect resolution (cracking, wrinkling, springback, scoring, strain lines).
How Deep-Drawn Part Difficulty Is Classified Deep drawn parts are seamless components formed by pulling a flat blank into a shaped die, and they range from simple cups to difficult thin-walled housings. Not every “deep drawn part” is equally hard to make. Shops grade difficulty on a spectrum because the difference between an easy cup…
The limiting draw ratio (LDR) is the maximum blank-diameter-to-punch-diameter ratio a sheet metal can be drawn in a single operation before it tears. The limiting draw ratio (LDR) is the largest ratio of blank diameter to punch diameter a sheet can survive in a single draw without fracturing: LDR = Db ÷ dp. Published first-draw…
Draw ratios, material selection, achievable tolerances and what to put on a drawing so the first deep drawn cover quotation is the right one.
