With the rapid development of modern industry, investment casting has become an important process in the field of precision casting applications. It is used in almost all industrial sectors. Many fine castings such as aircraft engine blades need to be formed by investment casting. Therefore, the precision casting wax new material technology used to make complex casting molds is not only the key to industry competition, but also an important symbol of the country's scientific and technological strength.
Among them, a Chinese local precision casting material technology company has sprung up in recent years. The company successfully developed precision casting wax technology, breaking the monopoly of foreign counterparts, becoming the first in China and the fifth in the world to have independent intellectual property rights and capable of producing high-end precision casting and aerospace and military waxes. This is SDXN Advanced Materials Technology Co., Ltd.
Hardcore strength to break the foreign monopoly of precision casting wax
On the track of research and development of new precision casting materials, Qingdao enterprises light up domestic production.
SDXN Chairman Shao Bin told Hay Think that, as a high-tech enterprise focusing on the research and development of new materials, precision casting wax products are one of the main projects of Sinocor, and unlike ordinary wax products, their service targets are mainly high-end precision Casting, aerospace casting, military casting and other precision casting industry cutting-edge manufacturing companies, "For example, the filling wax that must be used in complex precision casting at present, we are the only company in China with R&D and production capabilities." Shao Bin said, the company's Since precision casting wax products were tested and put into the market in 2017, many products have reached the international advanced level and can completely replace foreign imported products. The order volume has been increasing year by year. "This year's orders have reached 6,000 tons, exceeding the 4,000 tons in the whole year of last year. ."
High-quality customers in the aerospace industry
AVIC AJ, AVIC HY, AHYL Aviation Technology Group, SDJY Superalloy Casting Technology, SDWD Precision Casting, BJBM Precision Casting Technology Group, WXFWN [turbocharger precision parts manufacturer, Cummins joint venture in China]… In fact, just flip Looking at the list of customers who cooperated with Sinocor, it is not difficult to find that most of them are leading precision casting technology companies in the field of aerospace and aviation in China. And the reason why these "Top" companies in China's precision casting industry have one after another handed over the investment raw material orders that determine the quality of castings to a local private enterprise in China, relying on the hard core strength of SDXN products.
Although the investment casting process has a long history in China, after its use in industrial production, European and American countries have developed rapidly. Especially high-end precision casting wax technology has long been dependent on imports. "Precise casting wax is widely used in military equipment, ships, automobiles, telecommunications machinery, machine tools and other fields. As small as a valve, as large as engine blades, all precision casting waxes are used for investment casting." Shao Bin said, owned by Anglo-American The most advanced precision casting and raw and auxiliary materials. At the beginning of the company's research and development in 2013, the company introduced two high-level foreign technical personnel through high salaries to learn from foreign advanced technology and accelerate the speed of research and development. At the same time, we hired professors from Qingdao University and Xi'an Jiaotong University as technical consultants, and signed an industry-university-research cooperation agreement. After nearly 4 years of research and development cycle and investment of tens of millions of yuan in research and development expenses, Shao Bin and his team have successfully realized the "localization" of the precision casting wax technology that has long been monopolized by foreign counterparts.
At the 16th China International Foundry Expo in 2018, the company won the "Highest Award of China's Foundry Materials-Golden Tripod Award" for precision casting materials.
"We have achieved a breakthrough in both casting process technology and material production technology." Shao Bin told reporters that through independent research and development, the company has overcome many technical problems in the use of domestic raw materials and domestic equipment to produce high-end precision casting wax, and the company has produced products that meet international standards. Precision casting wax products realize independent control of key core technologies. Nowadays, Xinnuoco has 4 national invention patents and 8 utility model patents, filling the domestic gap, becoming the first in China and the fifth in the world (following Germany, Britain, the United States, and Japan) with independent intellectual property rights and capable of producing Enterprise of high-end precision casting and special wax for aerospace and military industry.
