China is undoubtedly a world leading foundry country. However, such a casting producing country still needs to import casting products from overseas. This is not because the total amount of castings in our country is insufficient, but because the quantity of high-end castings in our country cannot meet the domestic production requirements.

Steel casting manufacturing refers to the manufacturing activities of various finished or semi-finished products of steel metal casting. According to the "Classification and Code of National Economic Industries" formulated by the National Bureau of Statistics, China classifies steel casting manufacturing as black metal casting, which refers to the manufacturing of various finished and semi-finished products such as cast iron and steel castings. Its statistical level 4 code is C3130. The products in the steel casting industry mainly include cast iron and steel castings. In the steel casting industry, castings can be divided into three types based on their size: large castings, medium castings, and small castings. The competition among small and medium-sized casting production enterprises is relatively fierce.
