In the motorcycle/auto parts industry, as the most important category of products in the die-casting industry, the demand for motorcycle parts and components, especially automotive aluminum alloy die-casting parts, will greatly affect the overall development prospects of the die-casting industry. From the perspective of the structure of the entire car, in addition to a large number of precision die-casting parts for automobile engines, gearboxes, transmission systems, steering systems, and electronic control systems, large-sized components such as body frames have also begun to adopt aluminum alloy die-casting parts. The demand for metal die castings in the automotive industry will continue to grow in the future.
