Suzhou Jin Cheng Precision Casting Co., Ltd. in the aluminum alloy die casting trend of the advantages of analysis First, the advantages of technological innovation

(A) advanced material research and development and application capabilities

Suzhou gold Cheng closely follow the trend of high-performance aluminum alloy material research and development. The company has set up a professional material research and development team, in-depth study of the ratio and characteristics of alloy elements. Aiming at the stringent requirements of aerospace, automobile and other fields on the strength, light weight and high temperature resistance of materials, we have successfully developed and applied a variety of new aluminum alloy materials. For example, by adding specific ratios of lithium, scandium and other rare elements, we have developed aluminum alloy materials with a 30% increase in strength and a 15% decrease in density, which are used in the die-casting of aviation parts, not only to meet the demand for high strength of structural parts in aircraft, but also to effectively reduce the weight, and help improve flight performance and fuel efficiency. In terms of sustainable development of materials, the company actively invests resources to optimize aluminum alloy recycling technology. The establishment of a perfect waste aluminum alloy recycling system, through independent research and development of advanced melting and refining process, can be recycled aluminum alloy waste efficient purification, re-made in line with the requirements of high-quality die-casting raw materials, the recovery rate of up to 90% or more, greatly reducing the dependence on virgin aluminum, practice the concept of green production.

(B) the leading level of die-casting technology

1. Deep application of vacuum die-casting technology: Jin Cheng Precision is at the forefront of the industry in the field of vacuum die-casting technology. The company introduced a number of sets of international advanced vacuum die-casting equipment, and its localization improvement and optimization. By precisely controlling the vacuum degree, filling speed and pressure and other parameters in the die-casting process, it can reduce the internal porosity of die casting parts to less than 1%, which significantly improves the density and mechanical properties of the products. In the automobile engine block and other key parts of the die casting production, by virtue of the vacuum die casting technology, product strength increased by 20%, fatigue life extended by 30%, for the automobile manufacturers to provide a more reliable, high-performance parts and components of the solution.

2. Semi-solid die-casting technology active exploration and practice: the company actively engaged in semi-solid die-casting technology research and application. Formed a special technical research group, and domestic famous scientific research institutions, jointly carry out the research of semi-solid die-casting technology. At present, has successfully mastered the semi-solid aluminum alloy paste preparation technology, and semi-solid die-casting process applied to the production of high-end electronic equipment shell. The shell produced by this technology not only has more complex and fine appearance, but also the internal organization is more uniform and dense, and the heat dissipation performance of the product has been improved by 40%, which effectively meets the demand of 5G communication equipment for heat dissipation and miniaturization and light weight.

Second, manufacturing advantages

(A) complete and advanced production equipment

Suzhou Jincheng Precision Casting Co., Ltd. has a complete set of complete and advanced production equipment system. From the high-precision mold processing equipment, such as five-axis linkage machining center, can realize the complex structure of the mold precision manufacturing, to ensure the accuracy of the mold within ± 0.01mm, for the production of high-quality die-casting parts to lay the foundation; to the different tonnage of the advanced die-casting machine, covering the full range of equipment from 200 tons to 2,000 tons, to meet the different sizes, different degrees of complexity of die-castings of the production needs. At the same time, equipped with automated die-casting peripheral equipment, such as automatic pick-up robot, automatic spraying equipment, etc., realizing the die-casting production process of efficient automated operation, greatly improving the production efficiency, reduce labor costs. For example, in the large-scale production of automobile parts, automated production line can realize the production of 3 - 5 pieces of products per minute, production efficiency compared with the traditional manual operation increased by more than 50%.

(II) Strict quality control system

The company has established a strict and perfect quality control system, which runs through the whole process from raw material procurement to product delivery. In the procurement of raw materials, each batch of aluminum alloy raw materials is subject to strict composition and performance tests to ensure that the quality of raw materials meets the high standard requirements. During the production process, advanced quality inspection equipment, such as X-ray flaw detector and spectral analyzer, are used to conduct real-time inspection of die castings, so that potential quality problems can be found and solved in a timely manner. At the same time, a perfect quality traceability system has been established, each product has a unique quality traceability code, which can be accurately traced back to each link and responsible person in the production process. Through strict quality control, the one-time pass rate of our products reaches over 98%, providing customers with reliable quality assurance.

Market and Service Advantages

(I) Extensive and high-quality customer groups and market layout

Suzhou Jincheng has made remarkable achievements in market expansion and has a wide range of high-quality customer groups. In the domestic, and many well-known automobile manufacturers, such as SAIC, Guangzhou Automobile and so on to establish a long-term and stable cooperative relationship, to provide them with automobile engine block, gearbox shell and other core parts of aluminum alloy die-casting products. In the field of aerospace, we have cooperated with a number of enterprises under AVIC, and participated in the research and development and production of a number of aircraft parts. In the international market, the products are exported to Europe, America, Japan and South Korea and other developed countries and regions, for Boeing, Airbus and other international aviation giants, as well as Volkswagen, Toyota and other world-famous automobile brands to provide supporting services. By setting up sales offices and after-sales service centers overseas, the company responds to customers' needs in a timely manner and continuously improves the international influence of its brand, with its market share growing steadily year by year.

(ii) Customized service and quick response capability

Aiming at the diversified and personalized demands of customers for products under the industry trend, Suzhou Jincheng provides a full range of customized services. The company has a professional product design and development team, according to the different needs of customers, from product design, mold development to die-casting production, to provide one-stop solutions. After receiving the customer's demand, we can give the preliminary design plan within 24 hours, and complete the mold development and sample production within 1 - 2 weeks. For example, in the development of new 5G base station radiator for a communication enterprise, the company team according to the customer's special requirements on thermal performance, structure size and appearance, quickly organize R & D forces, optimize the design scheme, only 10 days to complete the sample production and delivery of customer testing, efficient service has won the high praise of customers.
