Aluminum alloy die casting process new trends and Jin Cheng Precision's way to deal with it

In recent years, aluminum alloy die casting process field is experiencing a profound change, many trends gradually appear. In material innovation, with the improvement of product performance requirements of various industries, the demand for new aluminum alloy materials with high strength and better corrosion resistance is surging. Especially the rise of new energy automobile industry, its pursuit of lightweight, safety and range, make the suitable aluminum alloy material research and development has become a hotspot, such as heat treatment-free aluminum alloy material research and development and application of the gradual rise.

At the level of process technology, integrated die-casting has become a development direction that has attracted much attention. Tesla adopts one-piece die-casting to produce the Model Y bottom plate assembly, streamlining the original 70-odd parts into one die-casting part, reducing weight by about 30%, lowering the manufacturing cost by about 40%, and greatly improving the production efficiency and product performance. This technology not only reduces assembly and welding processes, but also enhances the safety of the body skeleton, prompting many companies in the industry to layout. At the same time, semi-solid casting and extrusion casting and other technologies are also developing and maturing, for aluminum alloy die casting to bring a new process path. In addition, with the wave of intelligent manufacturing, aluminum alloy die casting process is towards automation and intelligent stride. The use of robot technology to achieve mold replacement, defect detection and other operations, not only can improve production efficiency, but also can reduce labor costs and error rate, to protect the stability of product quality. And, in the environmental protection concept deeply rooted in people's hearts now, energy saving and emission reduction and resource recycling in aluminum alloy die casting industry is becoming more and more important, green die casting has become the key element of the sustainable development of the industry.

In the face of aluminum alloy die casting process series trend, suzhou jincheng precision casting co., ltd actively layout, take many powerful measures. In the research and development innovation, Jin Cheng precision performance is particularly outstanding. The company has a strong team of more than 150 researchers, which gathered die-casting experts and mold professional engineers. Its long-term focus on die-casting new materials, new technology depth research and development. For example, the successful development of a new type of aluminum-silicon alloy for semi-solid rheological forming, the alloy after heat treatment, yield strength, tensile strength and elongation have reached the industry's leading level, the thermal conductivity is higher than similar products, to fully meet the market's urgent demand for high-strength and high-conductivity aluminum alloy materials. In process technology upgrading, Jin Cheng Precision is deeply involved in the industry's cutting-edge technology research. 2018, the company cooperated with Shanghai Jiao Tong University and Northwestern Polytechnical University to undertake the national key research and development plan manufacturing basic technology and key components key special “semi-solid rheological casting technology of aluminum alloy thin-walled parts (application demonstration class)” project, and Successfully passed the acceptance of the Ministry of Industry and Information Technology. Through this project, the company developed a set of high-quality aluminum alloy thin-walled parts rheological die casting and extrusion casting technology, the establishment of a semi-solid aluminum alloy rheological casting numerical simulation and mold design integrated computing platform, optimize the mold design and process, to ensure that the casting blanks qualified rate of more than 98%.

Jin Cheng precision also built 1600t, 4000t semi-solid rheological die casting demonstration production line and 350t semi-solid extrusion casting demonstration production line, equipped with a number of advanced precision machining centers and all kinds of ancillary facilities and large-scale precision measuring instruments and equipment, with a strong aluminum alloy die casting parts research and development, production and precision machining capabilities, to achieve the effect of large-scale production. In the field of industry-university-research cooperation, Jincheng Precision and Soochow University jointly established a postdoctoral innovation practice base, high-performance automotive lightweight casting aluminum alloy development and microstructure regulation and control of the subject to carry out research. Through the optimization of aluminum alloy ratio, the use of external electromagnetic stirring and other advanced technologies, to solve the aluminum alloy die casting inherent under the skin porosity and porosity and other problems, and effectively improve the mechanical properties and quality of products. In the intelligent production promotion, although there is no detailed information that Jin Cheng Precision in the application of robots, automated production lines and other aspects of the specific initiatives, but from the industry development trend and the company's emphasis on technological innovation, it is very likely that in the future to increase investment in the field of intelligent manufacturing, the introduction of advanced automation equipment and intelligent control systems, to enhance the automation of the production process and the level of intelligence, to Adapt to the industry development trend, improve production efficiency and product quality consistency. In green die-casting, the company is also very likely to optimize the production process, improve the process, improve energy efficiency, reduce energy consumption; At the same time, strengthen the production process of waste recycling and reuse, reduce the impact on the environment, practice the concept of green development, and promote the sustainable development of enterprises.
