It is difficult for us to distinguish the appearance of die-cast aluminum parts from ordinary die-cast parts. The quality of the blanks produced by the continuous casting and forging process is similar to the "first casting and then forging" process. The casting-first-forging process is very common: two sets of molds are required for the production of blanks, one for manual common metal mold casting, and the other for precision forging using a friction punch or hydraulic press.

Automotive lightweighting is the development direction of the world's automotive industry, and the lightweight material of automobiles is aluminum alloy. The direct benefit of lightweight technology is energy saving and environmental protection. In terms of driving, after the vehicle is lightened, acceleration is improved, and vehicle control stability, noise, and vibration are also improved. Considering the collision, the inertia is small during the collision, and the braking distance is reduced. Therefore, vehicle weight reduction is very important to save energy and reduce exhaust emissions. Research shows that for every 1 kg of aluminum applied to a car, a 2 kg reduction can be achieved. For every 10% reduction in the car ’s mass, for a normal car, that is, a 100kg reduction in body weight, fuel efficiency can be increased by 6% to 8%. Another advantage of lightweight body is that under the same power output condition, the power performance is good. And aluminum itself has good corrosion resistance, weldability, formability, and thermal conductivity. Automotive radiators made of aluminum alloy composites have the advantages of small size, light weight, good shock resistance, and long life. .

At present, the automobile industry has become China's pillar industry. Especially in recent years, China's automobile industry has entered the fast lane and has become a world's largest automobile producer and a potential consumer market in the world. In 2010, China's total automobile production will reach 16 million vehicles, and China's domestic demand will reach 10 million vehicles. As with the output, it will achieve double-digit growth for many years on the basis of increasing bases. The development of the automobile industry and the increase in the number of automobile owners have promoted the development of China's manufacturing industry and brought convenience to people's lives. At the same time, three major problems have also arisen: fuel consumption, emissions, and light weight. And lightweight will inevitably lead to a large number of applications of aluminum alloys in automobiles.
