Recently, auto parts companies in the United States, Europe, Japan, and South Korea have adopted a steel manufactured using a new process method (hydraulic forming technology). According to reports, this technology can reduce the production cost of parts by 15% and reduce the weight by about 30% compared with the traditional automotive steel processing technology. In order to meet the needs of auto and parts companies to reduce production costs, save raw material consumption, improve performance and quality, and achieve the goal of lightweighting automobiles, steel companies have vigorously developed and adopted hydraulic forming technology to produce automotive parts steel. In the U.S. market, the hydroformed steel required for automobile production grows at a rate of 20% annually. Japan's demand growth rate is 18%. In Europe, Germany, France, and Italy, the demand for hydroformed steel increases at a rate of 15% per year. South Korean auto parts companies have also begun to use this new process of processed steel. Hyundai Motor's modern steel pipe company last year hydroformed steel. The production line has been completed and trial production is now underway. Mass production will begin in May next year; Posco will invest USD 38 million in Kwangyang Iron and Steel Works to build a steel production line for hydraulically-formed vehicles. It is scheduled to be completed in March next year and annual production can be completed. for. More than 1 million steel parts are needed for the production of automotive parts. Hyundai, Kia, GM Daewoo and Ssangyong will all purchase steel from here. The steel processing technology used for hydroforming vehicles has many advantages. There are more than 20,000 parts and components required for automobile manufacturing. These parts require steels of different specifications and thicknesses. The basic technology of steel plate hydraulic plus 51 7-art is: steel is not made into a plate shape, but is made into a cylindrical pipe shape, and then high-pressure jets of high-pressure water are added inside the round pipe, and the steel is evenly subjected to water by the force of high-pressure water. The pressure forms a wide variety of components. The thickness of the steel components and the strength of the external forces are balanced to achieve the degree of consistency in all parts. This is an advanced technology that is completely different from the traditional automotive steel processing technology. One component is completed at one time, so the production cost can be reduced. Yoon Chang-wan, deputy general manager of South Korea's Posco, said in an interview recently: “Pohang’s production capacity of hydraulically-formed automotive parts will expand by 2-3 times in the future, and it will be exported to Chinese automobile manufacturers in the future.
