Sheet-meal stamping uses more than 6000 tons of steel a year. Most of the components produced at Norma are related to safety and resistance. Therefore, in sheet-metal fineblanking, we mainly use cold-rolled carbon steel C60E and C45E. In progressive sheet-metal stamping we use hot- and cold-rolled low-carbon steels and microalloyed steels.
Sheet-metal fineblanking and forming on fineblanking presses have been our core competencies for more than 30 years. We take pride in the quality and accuracy of the components and the cleanliness of cutting surfaces. We work with a total of five fineblanking presses, all produced by Feintool. Pressing force in fineblanking ranges from 160t to 450t and the maximum thickness of the used sheet-metal is up to 5 mm. In the near future we aim to increase the output of the presses by investing into a new press with a bigger pressing force (up to 700t).
Most of the fineblanking dies used at AS Norma are designed and produced in our own tool plant.
Progressive stamping In sheet-metal progressive stamping conventional eccentric presses and automatic press lines are used with pressing force up to 315t and the thickness of sheet-metal up to 4mm.
