My country's output is second to none in the world, and it has been the world champion for more than ten years. However, relevant experts said that the growth rate of my country's casting output will slow down significantly in the future. It is understood that since the second half of 2012, the demand structure of castings in downstream industries has changed significantly. There has been a relatively large decline in the demand for domestic castings, which affects the changes in the total amount of domestic castings. In addition, as an important customer of the domestic casting industry, the automobile industry has been continuously optimizing its structure in recent years, which also affects the changes in domestic casting production to a large extent.

    It is reported that the total output of all kinds of castings in my country is 10,000 tons in 2019, which is a year-on-year increase, and the growth rate has slowed down significantly. From the perspective of the structural changes of various materials, the annual growth of aluminum alloy castings, ductile iron castings, gray iron castings has a slight increase, and steel castings has no growth. According to experts, it is expected that the increase in the total output of various types of castings in China will still be relatively small in 2019, and the slowdown in the growth rate has become an indisputable fact in the industry.
