Under the premise that small and medium-sized enterprises that do not have competitive advantages occupy a large proportion of China's sheet metal main body, how will China's sheet metal industry respond to increasingly advanced foreign advanced enterprises? What is the competitive advantage of the domestic sheet metal industry? The cluster-based development based on the main cooperation has become an urgent demand in the domestic sheet metal industry.

　　As a large-scale e-commerce platform dedicated to the development of China's sheet metal industry and enterprises, China Jinjin.com has effectively promoted domestic sheet metal by providing professional business service modules such as information supply, purchase information, enterprise library, industry information, and industry exhibitions. Communication and cooperation between enterprises provides an important platform for the casting and strengthening of the advantages of China's sheet metal clusters.
