            Product Details
            With the deepening of high-speed railway in the field of civil transportation, the technical problems in the lightweight of rail trains have become an important factor hindering the further development of high-speed rail. The base plate of traditional high-speed trains uses aluminum alloy as the main material, and carbon fiber material
            Compared with the material, it has great disadvantages in terms of weight and shock resistance.
            Relying on years of manufacturing experience in the industry, the company has solved the current situation of high mold requirements in the manufacturing of rail train components. Through the technology of mold heating and positioning, the company has developed a set of efficient mold production process that can meet the process requirements, meet the requirements of high shock resistance and high geometric characteristics of tram components, and the production efficiency is 50% higher than the traditional production method. According to the summary of key technologies of the company in the early stage of the project traction, the middle stage of the project product production and the later stage, the key technologies of lightweight high-speed rail are overcome, some major problems in the production and experiment process are solved, and guiding opinions are put forward for large-scale mass production.
