The rapid development of China's automobile and motorcycle industry has led to a significant increase in production for many years. It ranks first in the world and drastically increases the demand for complex, large-scale, precision casting molds. As an important support for the foundry industry, the foundry mold industry has achieved Unprecedented opportunities for development. The scope of application of castings is very wide, and it covers almost all industrial fields. Among them, the castings of automobile parts are ranked first in terms of their quantity, variety, strict requirements, high quality and non-ferrous metal materials. The largest share of the entire foundry industry. In the next few years, the production of cast molds in China will still receive strong thrusts mainly from the domestic auto industry, which will surely achieve even more brilliant achievements. In the current wave of economic globalization, the international division of labor is taking shape. Many foreign companies, based on cost pressures, have purchased a large number of castings in China and even set up casting production bases in China. On the other hand, the production level and capability of China's casting molds have been greatly improved, and the gap between the quality of molds and the international level has continuously narrowed. The high quality and low price drove foreign purchases to soar, and the huge demand for overseas mold market played a significant role in promoting China's mold industry.
