Automobile die-casting parts have some advantages that other die-casting parts can't compare, such as beauty, light weight, corrosion resistance and so on.

Especially since the automobile lightweight, automobile die-casting parts have been widely used in the automobile industry. ​

(1) The chain shell is used to connect the cylinder block and oil pan. The chain shell has been tested by oil pressure and air pressure during automobile driving, so it puts forward high requirements for the quality of products.

This kind of automobile die-casting parts will show deformation and unqualified external quality in application, so it is necessary to try to ensure that the products have small processing and deformation. Although the investment cost of such auto die-casting parts is high, the consumption rate is also high. The total cost is not too high for the mass consumption of the auto industry.

(2) The engine block is the "heart" of the automobile. The key to the quality of the automobile lies in whether the engine is of good quality, and the central component of the engine is the cylinder block. The cylinder block is made of high-pressure casting or sand casting. However, from the current comparison of the automobile engine, the mainstream models and automobile manufacturers all use aluminum alloy die-casting cylinder block.

Although the cost of aluminum alloy die-casting cylinder block is higher than the first two manufacturing methods, with the rise of oil and the development of automobile lightweight requirements, aluminum alloy die-casting cylinder block is more and more widely used by automobile manufacturers.

Because the heat conduction function of aluminum alloy is better than that of cast iron, the use of aluminum cylinder head and cylinder block can improve the shape of the engine, improve the thermal efficiency and greatly improve the efficiency of the engine.

The casting process of the cylinder block is extremely complex, which is known as the "pyramid" in the technology of automobile die-casting parts. If you master the manufacturing technology and process of the cylinder block, you will master the "central secret" of the technology of automobile die-casting parts.

(3) Bracket parts are used for the connection of key parts such as automobile engine and transmission. Although they are not as important as cylinder block and cylinder head in appearance, in essence, the quality of these parts plays a decisive role in the performance of the whole automobile. This kind of automobile die-casting parts plays a major role in die-casting consumption.

(4) The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to block the shell of the crankcase as an oil storage tank, avoid the entry of impurities, collect and store the smooth oil flowing back from the friction surfaces of the diesel engine, dissipate local heat and avoid the oxidation of the smooth oil.

Although aluminum alloy die-casting oil pan is not as strong and durable as steel plate stamping, it has the advantages that steel plate oil pan does not have, that is, light weight and good heat dissipation.

The composition and strength of aluminum alloy die castings have a very important impact on the quality of automobile die-casting parts. After adjusting relevant elements, the tensile strength of automobile die-casting parts can be increased and the activity can be improved.

Based on the local design and manufacturing of automobile die-casting parts, the discussion of aluminum alloy die-casting technology and the development direction of automobile, it provides a huge market for die-casting consumption. Manufacturers should develop more automobile die-casting parts according to the market demand.
