The blank size, the draw ratio and the wall thinning are calculated before the die is run; the calculations are set out on deep drawing: process, materials and defects . Parts run on...
- What Is Annealing? Heat Treatment For Formed PartsAnnealing is a controlled heat treatment: the metal is heated to a temperature where its internal structure recrystallises, held long enough for that to complete, then cooled. The result is lower yield strength, higher elongation and softer metal, with the internal stresses from cold working largely...

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Need a DFM feasibility assessment for your project?
Send the engineering drawing (STEP or PDF) with the material grade, thickness and annual volume. Balford engineers then check it against the process window - draw ratio, wall thickness, tolerances, blank and tooling route - and come back with what is feasible and what is not. An answer on this page cannot replace that review.
