Fine Blanking

Fine Blanking is a metal forming process using dedicated hydraulic presses with three motions and complex tooling to produce ‘net shape’ finished parts in just one operations, or press stroke, with one or more steps of the material inside the tool.

Unlike Conventional Blanking, counter-pressure is applied on the component that allows the part to be cleanly sheared with straight edges and particularly good flatness tolerances that do not require secondary machinery operations, such as grinding or milling.
Fine Blanking has die clearances one-tenth of those used for Conventional stamping, which helps eliminate tearing on the cut edge of parts. This technology is particularly relevant for the production of high-strength two-dimensional components and has been successfully gaining applications in the automotive sector, where quality and tolerances are paramount.
