It is understood that China's die-casting enterprises are mainly distributed in the south of the Yangtze River, but the proportion of enterprises in the area south of the Yangtze River in China is still in the minority. This phenomenon shows that there are many die-casting enterprises in China, but they are widely dispersed. In other words, there are many die-casting enterprises in China, and there are more than 30000 die-casting enterprises in China; Enterprises are distributed in different places.

In this regard, the relevant government has reduced small enterprises, and the reduction of small die-casting enterprises has more advantages than disadvantages for the whole die-casting industry. First of all, the total number of orders in the whole industry will not decrease. On the contrary, these orders will be obtained by other powerful enterprises, which will be more conducive to these enterprises to increase their investment in R & D. If the foundry enterprises are controlled within 10000, it will be more conducive to the development of the industry. For foundry enterprises, the order requirements are higher, the batch requirements are greater, and the quality requirements are more stable.
