1. Chain housing cover

It is mainly used to connect the engine block and oil pan. It always bears the test of oil pressure and air pressure during vehicle driving, so it puts forward high requirements for product quality. This kind of parts will mainly have product deformation and unqualified internal quality defects in die-casting production, so try to ensure that the products have small machining allowance and deformation. Although this product adopts aluminum alloy die casting, which has high investment cost for tooling, fixtures and molds, it has high production efficiency. Compared with mass production in the automotive industry, the total cost is not too high.

2. Engine block

The engine is the "heart" of the automobile. The key to the quality of the automobile lies in whether the engine is of good quality. The core component of the engine is the cylinder block. The early cylinder block only used low-pressure casting or sand casting, but from the current comparative analysis of automobile engines, most mainstream models and automobile manufacturers used 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 rapid rise of oil price and the rapid development of automobile lightweight requirements, aluminum alloy die-casting cylinder block is more and more widely used by automobile manufacturers. Because the thermal conductivity of aluminum alloy is better than that of cast iron, the use of aluminum cylinder head and cylinder block can improve the working state of the engine, improve its thermal efficiency, and greatly improve and improve the working efficiency of the engine. The casting process of cylinder block is extremely complex, which is known as the "pyramid" of aluminum alloy die-casting technology. If you master the manufacturing technology and process of cylinder block, you will basically master the "core secret" of die-casting technology.

3. Support parts

This kind of parts is mainly used for the connection of key components such as automobile engine and transmission. Although it is not as important as cylinder block and cylinder head on the surface, in essence, the quality of this kind of parts plays a decisive role in the safety of the whole automobile. The main problem of this kind of parts in the process of die-casting production is deformation.
