Turkey 225 km/h high-speed EMU project(High rail )Building on its established capabilities in precision machining of individual components, automated welding of major parts, and complete bodyshell welding for railway vehicles, company has won the new-type railway vehicle complete bodyshell welding projects once again. This demonstrates that its full-vehicle manufacturing capabilities have earned consistent recognition from the market.The implementation of this new project will further validate the company’s comprehensive strength in complete bodyshell welding technology, quality control, and production capacity and delivery capabilities.
In response to China’s 14th Five-Year Plan and railway vehicle component requirements, we have developed a new PC alloy material tailored for the full life cycle of rail transit vehicles ,realizes the goals light weight, high strength, and eco-friendly lightweight. It has been successfully trialed on CR450 high-speed EMU prototypes (CRRC Tangshan) and put into service on CR250 trains for the Sichuan-Tibet high-speed railway (CRRC Changchun).
Turkey Gaziray Commuter Train Project (Urban Rail) Since its founding, company has focused on railway vehicle welding, mastering automatic welding technologies for underframe, side walls and other major components, and it further achieving capabilities for complete bodyshell welding and final assembly . Realizing full-process layout from “single part machining” to “major component welding” and finally “complete bodyshell welding”.
Partnered with Harbin Institute of Technology to industrialize metal superplastic forming technology, launched the first superplastic-formed aluminum alloy driver’s cab and interior components for the Jinyi East suburban rail train.
Participated in the R&D of next-generation upgraded products for high-speed intelligent EMUs , including driver’s cabs and composite floors,etc.
Established Chengdu branch; developed three types of cabs for Beijing-Zhangjiakou and 400 km/h projects.
