Design is the key to the innovation goal of the casting industry. This is mainly because the design stipulates the structure of the casting, the materials used, the production process of the casting, and the quality of the casting. The design almost controls the whole process of casting production. Therefore, to realize innovation in the casting industry, it must be traced back to the origin, starting from the design stage of castings. At present, the structure of China's casting products has a tendency of solidification, and the structure of casting products is old. As a result, China's casting industry is still in place, and changes have not developed. In addition, the innovation of the casting industry is not enough, which has a great relationship with the casting process designed by the casting designer and the casting selection. Designers cannot develop and utilize new casting production techniques. Ingenuity at the time of selecting casting production materials is also an important cause of low innovation in castings.
Design is a unique work. In the production of castings, if the designer does not have any breakthrough, it is very difficult for the casting production to introduce new ideas and achieve innovation. Therefore, to achieve the goal of innovation, the casting industry must start with the key and core of design innovation.
