EcoInCure: Space-Saving Oven Technology for Electric Cars for the mobility of the future. The Chinese start-up also insists on stateof-the-art standards for manufacturing and commissioned Dürr to construct a complete paint shop. Distinguishing features are a 20% reduction in footprint and the use of pioneering technologies. An example of this is the EcoInCure oven, which is ideal for electric vehicles. From October 2019, the new Chinese OEM Future Mobility Corporation (FMC) will produce electric vehicles under the Byton brand at its company site in Nanjing. The new paint shop is initially designed for 150,000 vehicles per year – equivalent to 30 units per hour. Growth has already been factored in, since the capacity can easily be doubled. Electric mobility goes hand in hand
