Focus processes: fine blanking and thinning deep drawing
What parts are typically fine blanked?
Answer
Choose another supplier if… The part is a seamless drawn housing or sleeve within Ø250 mm. The part is fine blanked and the cut edge is functional: shims, washers, brackets, IGBT copper base plates. The part needs in-die tapping or four-slide side piercing in a progressive tool.

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.
