Precision casting is an important part of the automobile industry chain. About 20% of the spare parts in the manufacturing of a vehicle belong to the casting parts. As a downstream industry in the automobile industry chain, precision casting mainly provides cylinder blocks and pipes of various major systems, such as engine and transmission cylinder blocks, intake manifold and exhaust manifold. Of course, many precision casting companies are not linked to the automobile industry, and many industries now need casting parts.

The development of automobile industry, especially the development of domestic automobile industry, will promote the expansion of domestic precision casting industry. At present, domestic cars, especially SUV models, account for a large share of the automobile sales. Moreover, many models in the SUV sales list are domestic cars, and these models are not exclusively owned by one automaker. And the different geographical locations of these auto companies can make the development of precision casting industry show uniformity, and will not let the technology concentrate in a certain region, so the development of precision casting will not be greatly limited, even if it is linked with automobiles.

With the decrease of regional nature, many precision casting enterprises have customers all over the country, and even overseas cooperation. Now both at home and abroad, the demand for high-precision precision casting parts is very strong. After all, with the change of products, the precision will be higher and higher. This also correspondingly put forward higher requirements to the precision casting industry.
