Importance of Sand Casting in the Automotive Industry

1.The basic principles and characteristics of sand casting process

Sand casting is a traditional metal casting process. Its basic principle is to inject molten metal into the sand mold through the pouring port, and obtain the required parts after cooling and solidification. Sand casting process has the characteristics of low production cost, short manufacturing cycle, and suitable for parts of various sizes and shapes. In addition, the surface of parts produced by sand casting process is rough, which requires subsequent processing and surface treatment.

2.Application of sand casting in automobile cylinder block production

Sand casting technology is widely used in the production of automobile cylinder blocks. The engine cylinder block of an automobile is a very important component, and sand casting technology is one of the most widely used manufacturing processes. Sand casting has excellent molding performance and can produce high-quality, high-precision, and smooth-surfaced cylinder parts. At present, this process has been widely used in the production of various types of engine cylinder blocks such as gasoline and diesel engines. The advantage of sand casting is that it can produce stable cylinder block size and precision, and can also produce more complex shapes.

3.Application of sand casting in automobile crankcase production

Sand casting technology also plays an important role in the production of automobile crankcases. The crankcase is another important component in the automobile and an important part of the operation of the entire automobile engine. The production of the crankcase requires a highly precise production process, and the application of sand casting technology can meet this requirement. The crankcase parts obtained by sand casting have a smooth surface and high dimensional accuracy, and have obvious advantages in the accurate assembly of crankshafts, connecting rods, valves and other components.

4.Application of sand casting in the production of automobile steering system parts

The steering system is a basic component of the automobile driving system. It is responsible for converting the driver's instructions into power direction and controlling the direction of movement of the vehicle. Many parts need to be manufactured by sand casting, such as steering drive shafts, steering housings, steering baffles, etc. These parts must withstand high pressure and large loads, so the use of sand casting technology can ensure their quality and reliability.

5.Application of sand casting in the production of automobile chassis

Chassis refers to the bottom parts of the car, including the frame, suspension system, transmission system, etc. These components need to be manufactured by sand casting. The frame is usually composed of multiple parts, each of which needs to be manufactured by sand casting, such as the front and rear of the car. The suspension system requires many parts, such as suspension brackets, suspension arms, etc.

6.Application of sand casting in the production of automobile brake system components

The brake system is an important part of the car. The parts involved in sand casting include brake calipers, brake discs, etc. These parts are crucial to the safety and reliability of the entire brake system.

In short, sand casting occupies a very important position in the field of automobile production, and is mainly used to manufacture high-performance and complex automobile parts. With the continuous development of automobile technology, sand casting technology is also constantly improving and innovating to meet the ever-increasing quality, efficiency and environmental protection requirements of the automobile industry.
