Monocrom at 31st IESE Auto. Novel approach for fuel efficient vehicle
Monocrom at 31st IESE Auto. Novel approach for fuel efficient vehicles >CIAC, or the Cluster of the Automotive Industry in Catalonia, selected Monocrom to participate in the 31st IESE Auto, which is one of the most important symposiums in the automotive industry in Europe. The title for this year was “The Battle for Automotive”, referring to the current situation of the sector, with the Industry 4.0 opening the door to new players such as the “big data” companies, and with the new trends of digitalization of all business areas, increased regulation, irruption of the electric car, and so on. Taking into accou Monocrom, presented the results of a novel approach for heat assisted roll forming of metal sheet based on a direct diode laser concept. This work has been developed in collaboration with the American multinational producing automotive parts Adient and the research center Aimen under the EU-founded project LASHARE (FP7-2013). Metallic profiles are widely used in the automotive industry. Considering steel as number one material for load intensive high volume parts, manufacturing technologies for Ultra High-Strength Steels (UHSS) are required to enable a continuous development in terms of weight reduction, stringent safety regulations, emissions reduction, solid performance, at affordable costs. UHSS when processed at cold temperatures are prone to spring-back and cracking, making them extremely difficult to process by bending. Heat assisted forming is found to be the best solution for improving the formability of UHSS. The metal sheet is heated up by the laser source during roll forming and the bending is carried out at elevated temperatures avoiding cracking of the material. Since the UHSS are highly sensitive to temperature cycle, heating must be done with a very controlled and reliable power source. As opposed to the induction heating, a laser source is less sensitive to vibrations of the metal sheet and variations in the distance between the laser source and the metal.
