Integrated Design of Automobile casting
With the automotive energy saving and reduce the cost of production requirements continue to increase, make full use of the advantages of casting, the original stamping, welding, forging and casting forming several parts, through reasonable design and structural optimization, to achieve integrated parts casting Forming, can effectively reduce the weight of parts and reduce unnecessary processing technology, in order to achieve the weight of parts and high performance.
The development trend of automobile casting integration is more obvious in the development of nonferrous alloy castings. In order to make full use of the casting process to achieve the characteristics of the production of complex structural castings, there have been integrated design of the door panels, seat skeleton, dashboard skeleton, front frame and firewall and other integrated design of high-pressure castings, the size significantly larger than the current production Casting, the need for 4 000 ~ 5 000 t or even larger tonnage die-casting machine for production.
The weight of automotive castings
To ensure the strength and safety of the car under the premise of the car as much as possible to reduce the quality of the preparation, to achieve lightweight, thereby enhancing the vehicle's power, reduce fuel consumption and reduce exhaust pollution. The quality of the vehicle is reduced by 100 kg and the fuel consumption per 100 km can be reduced by 0.3 to 0.6 L. If the vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6% to 8%. With the needs of environmental protection and energy conservation, the weight of the car has become the world's automobile development trend, the weight of automotive castings has become one of the important direction of development of automotive castings.
