Focus processes: fine blanking and thinning deep drawing
How are multi-stage thinning draws and annealing sequenced?
Answer
For deep drawing, specify 3003 in O temper as the default, 1050 or 1100 where the draw is severe and strength is secondary, and 5052 or 5754 only for moderate draws where strength and corrosion resistance are needed. Never specify 6061 for a deep drawn housing. Always name the temper as well as the alloy. Frequently asked questions Is 5052 good for deep drawing?

- DC04 vs DT4E Pure Iron: Which Fits A Solenoid Housing?Under the press the ranking reverses. DC04 is bought for forming: its specification includes mechanical properties and a mill-controlled normal anisotropy that keeps a cup from earing badly and lets a single draw take a larger reduction, which usually means fewer stages and less interstage annealing...

The grade is decided by the sensor, not by convenience: 304 and 316L for pressure, ABS and exhaust-side temperature sensors; brass for coolant and water temperature sensor housings, where faster thermal response matters more than co...
- How To Calculate Blank Size For A Deep Drawn Cup?Does the blank size change when a part needs more than one draw? No. The blank stays the same for the whole part, because it holds all the material the finished cup will ever contain. What changes between stages is the preform diameter — the size of the partially drawn cup after each stage. Multi-st...
- Can A Deep Drawn Part Be Modified After Tooling Is Built?Balford designs and builds tooling in-house and deep draws parts up to Ø250 mm on presses from 25 t to 350 t. The review starts from the current die state and the revised drawing, not from a generic minimum change charge. If a revised drawing adds a draw stage or requires interstage annealing, that ...
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.
