The « Fine Blanking»


We use the blanking technique for very wide pieces (14 mm) requiring their geometry to be precisely maintained. Fine blanking also makes possible regular cutting on flanks without cracks and tears, enabling us to avoid additional correction and tooling operations. With a production tool consisting of 19 hydraulic presses with a power of between 80 T and 630 T, Groupe ISTRA ranks among the European leaders in the fine blanking sector.
 
The « Classic blanking»

We use so-called " classic " blanking on correction presses or automatic presses. We transform all types of sheet metal, slit bands and pre-blanked flanks In automatic blanking, we can launch the manufacture of medium and small series with progressive tools.
