Laser-assisted sheet metal working by the integration of scanner system technology into a progressive die

Within the sheet metal working industry the demand for thinner sheet materials with very high strength is growing due to the increasing importance for saving energy and responsible usage of natural resources. High strength and low ductility restrict application of state-of-the-art technology to shear, bend or deep draw parts with the needed complexity and quality. The Fraunhofer IPT has developed a "hy-PRESS" system to combine laser-assisted preheating and conventional punching to a hybrid technology in a progressive die, which allows to shear, bend and deep draw high strength materials with a high quality and complexity in progressive dies.
