Sheet metal processing is usually refers to the 6mm below the metal sheet of a kind of integrated cold processing technology, including cutting, punching, cutting, composite, folding, welding, riveting, stitching, forming (such as auto body), its significant feature is the same part thickness. Sheet metal processing industry is closely related to people's daily life, although the metal sheet metal processing in the proportion of only 20%-30%, but almost all of the manufacturing industry will be involved in sheet metal processing. According to statistics, the number of sheet metal processing industry in our country more than 3, the number of employees more than 180, the annual production of sheet metal parts more than 4000 tons, sales amounted to 5000 yuan.
Sheet metal processing industry to enhance the domestic machinery manufacturing industry, communications electronics industry, automotive and shipbuilding and other industries have a certain importance, with the gradual rise of these industries, but also led to the rapid development of sheet metal processing industry. At present, the industry cluster of sheet metal in the region or manufacturing industry developed rapidly. In the Pearl River Delta, Shenzhen, Suzhou and the Yangtze River Delta region of Cangzhou Bohai and other places, there have been dozens or even hundreds of industry clusters, has formed a local industry chain. The emergence of sheet metal industry is mainly for the domestic and international machinery manufacturing enterprises to do a supporting sheet metal processing, domestic and foreign machinery manufacturing enterprises to cultivate the sheet metal processing industry, and the sheet metal processing industry has promoted the rapid development of machinery manufacturing enterprises.
        China as the world's processing manufacturing center, attracting a large number of foreign capital investment, due to the wide scope of application of sheet metal processing, so some of the best international sheet metal enterprises into China, such as Japan's day Tian Co., Ltd., Murata machinery plant type club; enterprises have a good technology and capital advantage, sheet metal processing in the domestic market occupies a higher market share.                     Compared with the international enterprises, domestic enterprises still have a certain gap, the domestic general domestic equipment used in the domestic equipment, the equipment married rate is not high, the efficiency is low, there is a technical bottleneck, so at the low level of the industry. But after years of development, China has nurtured the a number of larger scale, the development prospects good enterprise, such as Taiwan's Foxconn Group, Shengming group, Jinfeng shares, Coxon group; Ridong technology in Hong Kong; mainland Dongshan precision, Conghua metal, Renda group, ZTE, Haili metal. At the same time as China's sheet metal processing market continues to expand, the future development of the industry will be a sign of polarization, weak enterprises in the fierce competition is eliminated, and some of the advantages of brand companies will be further developed.
