The diversity of application fields of aluminum alloy die casting products is one of the main characteristics of die casting production in China. With the wide use of die casting in industry and daily production, higher requirements for quality, performance and scope of use are put forward. Reduce the cost of die casting, realize the function of the structure and meet its use needs on the premise of lower material consumption and manufacturing cost, so as to obtain high technical economy in the production of die casting

(1) The rapid development of die-casting aluminum shell and zinc alloy shell of automobile connector has been very obvious in China in recent years, which has effectively promoted the rapid development of die-casting of new energy automobile connector

(2) At the same time, the die casting of automobile parts has formed a huge market, and the lightweight die casting has become an important development trend. Take automobiles as an example. The goal of the new generation of automobiles is to reduce the fuel consumption to 3ml per 100km. The strong domestic and external demand of the automobile industry has promoted the rapid development of the parts manufacturing industry, in which aluminum alloy castings account for a large share

(3) There is also a great demand for new energy, smart home, connectors, electric tools and other products, which has stimulated the enthusiasm for the development of the die casting industry. In recent years, die casting production enterprises and scientific research institutions have developed to nearly 100 in the original places. Among them, Yinchang Precision Hardware is developing rapidly, and its industrial chain is leading from basic hardware accessories to advanced connector shells, power tools, smart home accessories, etc

Characteristics of aluminum alloy die-casting material:

In order to obtain high-quality die-casting, apart from reasonable part structure and shape, complete die-casting, accurate die-casting process and die-casting machine with excellent process performance, die-casting materials account for a large proportion of the total cost of die-casting parts. This not only depends on the cost of the material itself, but also depends on the type and performance of the alloy, thus affecting the life of the die casting die. Therefore, it determines the type of die casting machine used and the die casting process suitable for die casting production

According to the characteristics of aluminum alloy die casting process, the alloy materials used in die casting must have the following properties:

1. It has sufficient high temperature strength and plasticity, low heat brittleness, and can meet the mechanical property requirements of parts

2. It has strong fluidity at overheating temperature and is easy to fill complex cavities, so as to obtain die casting with good surface quality

3. The crystallization temperature range is small to prevent excessive shrinkage pores and looseness in die casting

4. The linear shrinkage and cracks shall be as small as possible to avoid affecting the dimensional accuracy of die castings

5. The processing performance shall be corrosion resistant and meet the requirements of processing and use environment

In modern die casting production, the quality of die casting is closely related to die casting, die casting equipment and die casting process. Among them, the die casting mold is very important to provide the molten metal with specific shape, performance, quality, cooling and die casting molding. Die casting die is the carrier that determines the product performance, specification, shape and dimensional accuracy. Advanced mold design and manufacturing, basic theory and common technology research and development, new technology and key technology research, mold flexible processing and standardized automatic production technology research reflect the technical content of the entire die casting production process and the precision requirements of die casting, so as to repeatedly obtain the quality of die casting and mold that meets the technical and economic requirements and has stable quality

Die casting die is an indispensable process equipment for smooth die-casting production process and ensuring die-casting quality. It is the specific implementer of die-casting equipment efficiency, high performance and excellent quality of die-casting process. It is also a decisive part of process improvement and new product development. The forming mechanism, process and technology of die casting alloy materials, as well as the analysis of die casting filling process, have been gradually improved in theory and sublimated in practice. Yinchang precision hardware is constantly popularized and improved in the process of die-casting process parameters and detection technology. With the wider application, the automation of die-casting production process will gradually improve, providing more favorable output for the famous industry
