In recent years, the global electric vehicle has developed rapidly, about 3.24 million electric cars were sold all over the world in 2020.
At present, the most concerning problem of electric vehicles is endurance, using aluminum alloy can greatly reduce the weight of the car and improve endurance. The EV battery tray mainly adopts 6-series aluminum profiles. 6-series aluminum alloy has good plasticity and excellent corrosion resistance, especially no stress corrosion cracking tendency and good welding performance. Therefore, 6-series aluminum alloy profiles are especially suitable for the application of battery aluminum trays.
To meet the market demand, PRATIC launched an automatic production line for new energy vehicles battery trays. The production line is divided into 7 parts and adopts international advanced welding friction stir technologies, realize the integrated molding of products, high efficiency, high speed and high precision.
