Casting products occupy a large ratio in various auto parts. There are various kinds of casting products such as automotive engine block, cylinder head, gearbox housing, intake manifold, exhaust manifold, crankshaft, camshaft, piston, and wheel hub, etc. However, in comparison with developed industrial countries, China’s automotive castings products still accounted for little as to the total output sand casting china. According to statistics, American auto castings account for 33% of the total production, while ours only account for less than 20%. There are many situations about this industry.
Firstly, the rapid development of auto industry drives the automotive castings industry which is one of the major downstream industries. About 10.5% parts of a vehicle are iron castings, and 6.4% are aluminum castings. These castings not only have large quantities, but also have high quality requirements. With the continuous development of China’s automobile industry, automotive castings production also increases. According to statistics, in 2009, China’s automobile production and sales volume exceeded 13.5 million, and the automotive casting production reached 10.33 million tons. It is expected that the production of them will reach 11.48 million tons if the auto output in 2010 reached 15 million.
The rapid development of the automobile industry provides a lot of opportunities for our automotive casting products. At the same time, with the requirements for lighter and energy-saving, the demands for non-ferrous castings will be further expanded. Since 2000, China has become a veritable casting manufacturing country with the largest production in the world.
Secondly, the export of these products is in the downward trend. Although China is the world’s leading casting manufacturing country, we are still far from casting power. The rapid growth of our production is at the expense of the high energy consumption, high resource consumption, and pollution of the environment, etc. In addition, compared to some other products such as stamping parts and fasteners, our automotive castings are still at a low-end level. And they can be easily affected by the market fluctuations. The financial crisis in 2008 had much impact on our casting industry. As a result, it had a sharp decline.
