Die casting parts are widely used, especially in the automotive industry, the demand for die castings is very considerable. Looking at the development of aluminum die castings in China, in recent years, the production capacity of aluminum die castings in China is constantly expanding. It is understood that in recent years, the output of aluminum die castings in China has been increasing year by year, and the development is very good. The reasons are as follows:

Driven by the trend of automobile lightweight, there is a huge demand for aluminum die casting market. With the optimization and upgrading of automobile industry in recent years, aluminum castings are gradually used to replace gray iron castings, thus continuously stimulating the continuous growth of demand for aluminum alloy die castings. Secondly, due to the development of die casting industry, the demand for aluminum alloy die casting is increasing. Thirdly, driven by the trend of economic integration, the focus of die casting production has gradually shifted to China. In addition, China's labor force and aluminum resource advantage [- 0.99%], the domestic die casting industry presents a trend of rapid development. In other words, the continuous expansion of China's aluminum alloy die casting industry is the result of the market, which is fundamentally different from the overcapacity caused by the expansion of the entire casting industry in China.

There are two characteristics of die casting deformation: one is the overall or local deformation; the other is that the geometry of die casting does not conform to the drawing. The reasons for this situation are: poor casting structure; premature opening of the mold, resulting in insufficient rigidity of the casting; improper setting of the ejector pin, resulting in uneven force during ejection; improper gate position or gate thickness, easy to deform when cutting the gate; rough surface of the mold causes high resistance and deformation of the product during ejection; too high mold temperature leads to no solidification of the casting or excessive force during ejection , causing product deformation.

For the problem of die casting deformation, the solution is to suit the remedy to the case, such as improving the casting structure; reasonably adjusting the opening date and holding pressure; reasonably setting the ejection position and the number of ejector pins; changing the gate position to reduce the gate thickness; strengthening the mold surface treatment to reduce the demoulding resistance; controlling the local mold temperature to maintain the mold thermal balance.

Die casting parts need to be firm in the process of packaging, so that they can be well cleaned in the storage period. The name, quantity, manufacturing date and the name of the receiving and sending unit should be indicated on the surface of the product.

After processing, die castings should be stored in a ventilated, dry and non corrosive gas environment. The aluminum materials used in the products have good plasticity and fluidity in the process of use, so the products can be made into products with complex shapes.

Die casting processing has a high precision and the surface finish of the product is very high. To this extent, it can greatly reduce the amount of mechanical processing of castings, reduce the labor intensity of equipment, and save materials and power during processing.

Speaking of die-casting aluminum parts, many people may not know what this is, but if we change this industrial term to a popular term, we can understand. The so-called die-casting aluminum parts are actually made of aluminum parts with specific industrial mold. Like any other kind of parts, this kind of parts is also used as accessories. The only difference is that the materials of the parts are different. In daily life, there are many places that need to use die-casting aluminum parts, such as the automobile industry. In the process of automobile production, most of the internal pipe fittings of the automobile are made of this kind of aluminum parts. The automobile pipe fittings made of aluminum parts are not easy to rust. In addition, this kind of aluminum parts can also be used in many other fields, such as metallurgy, machinery, construction, chemical industry and so on. China's steel production and sales market are in the forefront of the global steel market, the development of die casting aluminum products industry has entered a new stage. The reason why the ratio of die casting aluminum parts is rising is that the tensile strength of die casting aluminum parts is nearly twice as high as that of ordinary casting alloy. Take an example to see, for aluminum alloy automobile wheel, frame and other parts, all hope to use high strength impact resistant material production, after the continuous development of science and technology, it is concluded that the use of die-casting aluminum parts will have better use effect.

Nowadays, the domestic manufacturing industry has entered the stage of blooming flowers. With the steady rise of China's economy and the continuous innovation and improvement of industrial level, the die-casting aluminum parts industry has achieved unprecedented development. Aluminum casting is a kind of precision manufacturing method which uses high pressure to press metal solution into complex metal mold. From all kinds of tools and products on the market, it is easy to see that many tools commonly used by the public are die-casting aluminum parts, and die-casting aluminum parts are one of them. Die casting aluminum parts in the production of very convenient, you can use die casting aluminum parts to produce some small parts. Although the production is very convenient, but the die-casting aluminum parts processing should pay attention to the die-casting aluminum mold in the work of the corresponding attention to the mold surface cleanliness, because the die-casting aluminum production if there is a little impurity on the mold will affect the quality of the product. In the selection of die-casting aluminum parts, the corresponding choice of precision die-casting aluminum parts, the use of this precision die-casting aluminum products produced by the product quality is very accurate, also can improve the product precision, and then the die-casting aluminum parts processing should pay attention to the size of the die-casting aluminum mold, to check this mold regularly, because the products produced by the mold are batch, if the size has Problems that the quality of the products produced will have problems, will cause heavy losses to manufacturers.
