In June of this year, the “Renewal” of China's standard EMU with completely independent intellectual property rights was officially put into operation, achieving another milestone in China's rail transit technology. Behind this progress is the unremitting efforts and struggle of many Chinese manufacturing companies. Chengdu Tianzhi Lightweight Technology Co., Ltd. is one of the glorious members.

Recently, Chengdu Tianzhi Lightweight Technology Co., Ltd. successfully completed the delivery of the first batch of magnesium alloy extruded side wall profiles and floor guide profiles for the Chinese standard EMU “Revival” train, with a total length of nearly 10,000 meters, passed China. The inspections of a company of CRRC Group and the successful listing of 11 batches of “Revival” EMUs. The next batch of "Revival" train magnesium alloy lightweight precision profiles are under negotiation. At the same time, the company has also completed the successful delivery of orders for magnesium alloy precision extruded profiles with a total length of more than 10,000 meters and a capacity of 25 subway vehicles.

Through independent research and development, Tianzhi successfully opened the whole technical process of material design, extrusion molding simulation, mold optimization design, extrusion process parameter optimization, on-site fine control, profile orthodontics, etc., and successfully realized large size and thin wall. The batch supply of complex extruded magnesium alloy precision extrusion profiles has broken through the bottleneck of current magnesium alloy precision extrusion technology. The successful installation of these magnesium alloy profiles on the "Revival" has enabled the world's highest operating speed of the EMU's in-vehicle components to be lightweight technology upgrades, achieving new weight reduction and energy saving goals. The shape of the end face of the batch is complex, the length of the fixed length is large, the processing is difficult, and the construction period is tight. During the production process, the company's leaders, technicians and operating staff work closely together to overcome various difficulties and complete the task as scheduled and in good quality and quantity.

The successful delivery of this order marks the official entry of Tianzhi into the ranks of suppliers of magnesium alloy lightweight products for rail trains, laying a solid foundation for the company's subsequent development and supply of more lightweight rail train products, and further strengthening Tianzhi's man-made realization. The belief that transportation equipment is light and tirelessly strives to struggle. At the same time, magnesium alloy EMU side wall and floor guides and other products were installed in batches on the “Revival” EMU trains for the first time. It is of great significance for expanding the application of magnesium alloys in rail transit and promoting the progress of rail transit lightweight technology. . This is a good start, indicating that the company has taken another step toward achieving the goal of lightweighting magnesium alloys for high-speed trains.

This is the success of Tianzhi Company's successful supply of new energy electric bicycle components, the realization of large-scale high-rare-magnesium alloy superplastic precision forging, the successful supply of integrated circuit rolling frame, new energy vehicle battery compartment assembly, magnesium alloy rail vehicle transition coupler. After the magnesium alloy/aluminum alloy axle box, another important rail train product successfully developed demonstrates the company's solid R&D, technical strength and the spirit of fighting to open up the market.
