Chengli Automobile Group Built The Country's Largest Shared Electrophoretic Coating Line For Special Vehicles

On Jan. 8th, Suizhou City, the capital of special purpose vehicles in China, held the Zengdu District Special Purpose Vehicle Industry Transformation and Upgrading Promotion Conference. More than 300 people attended the event, including representatives of domestic auto manufacturers, leaders of urban areas and government functional departments, as well as guests of Chengdu Yiwei, a leading domestic new energy vehicle chassis manufacturer, and reporters from provincial and municipal news media.

The country's largest shared electrophoretic coating line for special vehicles was built and put into operation by Chengli Automobile Group in Zengdu District, Suizhou City.

 Anti-rust treatment has always been an unavoidable topic in the special vehicle industry. Whether the anti-rust treatment is done well is directly related to the service life of the product. Before the emergence of electrophoresis technology, the pickling and phosphating process was widely used in the industry, and the service life of the product was relatively short, which was not conducive to environmental protection.


 In April 2022, Chengli Group's electrophoresis workshop broke ground, with a total investment of 130 million yuan. The workshop is 168 meters long and 27 meters wide. It can complete the electrophoretic coating of workpieces with a length of 9 meters, a width of 3 meters, a height of 3 meters and a weight of 5 tons. Operation, with an annual production capacity of 20,000 units, is currently the electrophoresis production line with the largest cell size, the most complete process, and the most advanced technology in Suizhou. Electrophoretic coating has the advantages of fast construction speed, reduced labor intensity, non-toxicity, convenient operation, etc. It has excellent adhesion, and its rust resistance and corrosion resistance are superior to ordinary paint and general construction methods.

At the Zengdu District Automobile Industry Transformation and Upgrading Promotion Conference held on the same day, representatives of Zhongheng Automobile, Qidong Automobile, Wanglong Automobile, Xinsheng Environmental Sanitation Technology, Yingtong Automobile and other enterprises signed electrophoretic coating business cooperation with Chengli Group protocol.


 It is understood that the new energy and intelligentization of the automobile industry is an irreversible trend of the times. Compared with passenger cars, the transformation of special vehicles to new energy is relatively slow, and it is necessary to speed up to keep up with the big development trend. According to the characteristics of the special automobile industry, the two levels of Suizhou City and Zengdu District have established the transformation direction of new energy, intelligence, scene and service. Guide vehicle manufacturers to introduce industrial resources and innovative forces to develop and produce new energy-specific chassis. At the same time, do a good job in strengthening the chain and replenishing the chain, building a new special vehicle testing and research and development base, sharing electrophoretic coating lines and other projects, filling the blank links in the industrial chain, and helping the transformation and upgrading of the special automobile industry.
