This paper summarizes three new common requirements of the digital management aspect in precision casting enterprises, and puts forward three corresponding techniques. They are: the production process tracking card technology based on the main-sub card mode; the workshop site production process processing technology based on the barcode; and the equipment data integration technology. Then, this paper discusses in detail the principle, application and effect of these technologies; to provide the reference for enterprises to move towards digital casting and intelligent casting.展开更多

They revealed the vestiges of wells, kitchen ranges, airing houses, wine cellars, distillers, wall-foundations, drainage ditches, pavements, ash-pits and brick pillars. The unearthed objects include stone articles, pottery, porcelain, bamboo and wooden wares, irons and bronzes, mostly wine vessels. The workshop began production in the Yuan period and continued to function in Ming and Qing times. It is early in date, long in duration, rich in remains and distinct in local character among the sites of this type. The discovery provides valuable data for studying the origin and development of ancient Chinese wine-distilling techniques.展开更多
