With platform concepts and a modern production, the Bosch Thermotechnik GmbH wishes to remain competitive in the worldwide market and further expand. The first major step is the integration of a modern CLOOS robot welding plant, based on which its concept and flexibility have significantly reduced tool changeover and production times in storage tank production. On the chained production system top and bottom shells are combined fully automatically with storage tank jackets. With clever mechanics and intelligent software the retrofit times reduce from 8 hours to around 20 minutes. Thus, Bosch can react to customer orders quickly and flexibly and is very economical even with low numbers.
