Good news! On March 14, 2019, CRRC held its 2019 Science and Technology Quality Work Conference in Qiqihar, where the "2018 CRRC Science and Technology Award" was presented on site. Among them, the laser cleaning project jointly developed by CRRC Qingdao Sifang Locomotive & Rolling Stock Co., Ltd., our company, and Huazhong University of Science and Technology: Research on Laser Cleaning Technology for Typical Rail Vehicle Components, won the Third Prize!
CRRC Science and Technology Award — Winner: Wuhan Xiangming Laser Technology Co., Ltd
This project addresses the cleaning issues of oxides and oil stains during the construction and maintenance of rail vehicles, and has completed engineering application research on laser cleaning technology for the surfaces of the car body and gearbox. The main technological innovations of the project results are as follows:
1. According to the pre-weld cleaning requirements for large aluminum alloy components, an integrated cleaning and welding operation mode and supporting equipment have been developed;
2. Developed laser fine cleaning technology for post-weld decolorization and dust cleaning of stainless steel car bodies, avoiding surface damage and reduced corrosion resistance caused by traditional cleaning methods;
3. Proposed a laser cleaning process for key gearbox components such as collector rings and ultra-thin copper washers, which are deformation-free, low-stress, and minimally damaged, solving the problem of irreparable ultra-thin copper gaskets. Currently, the results of this project have been widely applied in projects such as the construction of stainless steel car bodies for urban rail vehicles, gearbox maintenance of EMUs, and high-speed magnetic levitation aluminum alloy car bodies. This is the first time laser cleaning technology has been applied in China's rail transit industry, and it boasts broad application prospects and tremendous promotional value!
Since the establishment of our company, we have been committed to providing customers across various industries with high-quality, efficient, and comprehensive laser cleaning application solutions, as well as comprehensive pre-sale, in-sale, and after-sale services. The laser cleaning equipment independently developed and produced by the company has been well and widely applied in fields such as aviation, aerospace, automobile manufacturing, and rail transit—not only greatly improving customers' work efficiency and freeing up labor, but also fundamentally solving the drawbacks of incomplete cleaning by original methods, damaging substrates, serious air quality and noise pollution, and harming operator health, ensuring the health of customer employees and creating unlimited value and business opportunities for customers.
In the days ahead, Wuhan Xiangming Laser Technology Co., Ltd. will continue to innovate and strive for excellence, delivering perfect answers to every earnest expectation and entrustment of its customers. For Xiangming people, honor is a halo, but it is also history and the past. What drives us forward is not honor, but responsibility and mission!
Make laser cleaning a standard in workshops!
