Among them, die-casting manufacturing technology is an important processing technology for the production of electronic control housings of new energy vehicles. It has the characteristics of high efficiency and high precision. By quickly injecting molten metal into the mold cavity under high pressure and cooling and solidifying it in a short time, castings with complex shapes and high dimensional accuracy are obtained. In order to improve the manufacturing efficiency of die-casting of electronic control housings of new energy vehicles, continuous casting devices are used to improve the production efficiency of electronic control housings of new energy vehicles during die-casting manufacturing of electronic control housings of new energy vehicles.
