Abstract: From the turn of the century the automobile industry's development trend, combined with some typical automotive castings and several areas of concern, and expounds China's automotive foundry industry conditions and problems and challenges. And from technological innovation, management innovation point of view, put forward the implementation of small classes, large quantities of specialized strategies, the revitalization of China's foundry industry, a number of concept cars.

One. The main users of the casting - the automotive industry
Car was born over a century, the world now has 670 million cars in the service themselves, but also increase the momentum of the global vehicle population reduction. Global car production in 1950 to 10 million in 1998 to 51.9 million, of which: China was 163 million, ranking first in the world 10. The 21st century, Asian demand for cars will be located in the world. According to analysis, the next century, Asia will be an average annual growth in vehicle demand by about 7%. Much higher than the world average growth rate. China is a potential growth vehicle market, is the world's largest potential auto market. China's auto industry will sooner or later one of the world's largest auto industry.
Automobile driven by other industries are strong, the automotive industry will promote the development of metallurgy, energy, materials, chemicals, machinery, electronics and other industries, to promote highway, city construction and finance, insurance, trade, transportation, information, etc. the tertiary industry's prosperity. According to statistics, one in seven jobs in Germany, there is an auto industry related. Automotive industry to promote consumption, expand employment, improve people's living standards, promote economic development role is obvious. Therefore, to develop our country, while cargo trucks, cars developed very rapidly recently, and to encourage private car, the bank issuing private car credit, reform of vehicle taxes and fees are, as the increase in highway and cities to suburban and City health development, China's auto demand will increase faster.
63rd World Foundry Congress held in Hungary in 1998, the meeting report that the world's largest buyer of castings in the automotive industry. The United States is the world's casting production is highest, the United States casting the largest user of its automobile industry. China's vehicle production is not high, but out of China's automobile industry is becoming the main users of our castings. According to incomplete statistics, in 1998, China's auto output of cast iron is about 70 million tons of aluminum automotive parts production is about 80,000 tons. Auto industry is an important factor in stimulating the development of the manufacturing sector. Many large foundries in China, is China's automotive casting supply manufacturers.

Second, the young Chinese automotive foundry industry
As a cast of thousands of years ancient history, casting, automotive casting industry in China is only 40 years history. This young Chinese automotive foundry industry, basically under the planned economic system set up under the OEM-style self-sufficiency foundry. This is because the automotive industry itself is emerging infant industries in China, the whole community can collaborate for the automotive industry supply capacity, the level is extremely limited at the time. Therefore, the car foundry then "large", "small" is also a last resort. Automotive castings casting complex than the traditional industries, high quality requirements, supply beats faster, it is necessary to use a certain level of high productivity casting equipment, facilities, capital investment is higher. However, under the OEMs, OEMs are not the main body of expertise, so they can arrange the actual investment is very limited. Even the introduction of some foreign equipment, but also due to limited funds only the introduction of some of the major equipment, without the ability to introduce a full set of equipment, resulting in the casting than the same under the professional OEM factory machining, assembly plant and other professional skills to backward, production efficiency is low, often restricting OEMs "bottleneck." In struggling through the initial stage, the Chinese automotive casting industry is facing its customers - the automotive industry of ever-increasing demands castings, the foundry industry is facing increasingly stringent community demands. In order to implement sustainable development strategy, the need to achieve energy-saving vehicles and environmental protection goals. Therefore, the car must strive to improve fuel economy, emissions must be strictly controlled. EC has set out to develop fuel less than 3 liters / 100 km of the car, the goal of the United States is 80 miles / gallon of gasoline, (or 34 km / liter of gasoline). To achieve this goal, is an important measure to reduce vehicle weight, weight 100 kg per car, one hundred kilometers can save 0.3 liters of gasoline, decreasing by 10% of car weight can be reduced by 10% of vehicle emissions. To enable vehicles to reduce weight, it required the castings must be lightweight, thin-walled, precision, strengthening and toughening. Therefore, the car continued to be light weight cast aluminum castings to replace. Nearly a decade, the U.S. auto aluminum castings increased by 1.7 times to 2007, the U.S. car engine cylinder head 95% of the aluminum castings, cylinder block 50% of the aluminum casting. Aluminum castings per vehicle in Europe in 1990 was 55 kilograms, in 2006, will reach 98 kg. One-third lighter than the proportion of aluminum magnesium alloy castings in the car was on the application of a more substantial increase in trend. In recent years, the application of magnesium castings car 20% a year growth rate in 1996, GM produced cars, each car uses magnesium alloy castings 45, 1998, annual U.S. auto magnesium alloy castings have been as high as 1.3 million tons. China's car development is consistent with the trend of the world, China's vehicle emission requirements, step on to the EC emission standards (Euro 1 standard first execution in 2003, Euro II, standards ...), and Beijing has started, other cities are starting to perform. Therefore, the requirements of the automotive castings with the world trend is the same. Castings for automotive lightweight, thin wall, toughening requirements for China's automotive cast iron foundry workers the world level, the level of equipment and tooling and casting of raw materials level, forming a huge pressure. In China, automotive aluminum casting, but in recent years with the rise of the car industry has only just begun, cast magnesium car almost from scratch. Demonstration of China's automobile industry, the pressure is casting. On the other hand, society has no longer forgive the foundry industry this large energy consumption and pollution of big drift. Protection of resources, environmental protection is everyone's consensus. 1998 63 th World Conference on casting, casting has begun to issue environmental awards, the world's ten first foundry-certified by ISO14000 award. The overall level of China's environmental pollution in developed countries has been the equivalent of history's most serious level, China's automotive foundry industry must take the high efficiency, energy, materials, environmental protection, road, take the green cast of the road, no choice. Young Chinese automotive foundry industry long way to go.
Three. Several typical automotive castings
Even if China's automotive foundry industry was still young, but many domestic workers have appreciated the casting has a lot of water production capacity of China's automotive foundry industry equipment status. In fact, China's car with the classic cast such as cylinder block, cylinder head, etc., has not yet been realized, some domestic auto plants, still rely on imports of castings. We must put our automotive foundry industry and boost the level as quickly as possible. Here are some typical automotive castings from the start, the car foundry industry for further analysis.
