Development of precision casting
Investment casting, also known as lost-wax casting, produces precise and complex products that closely resemble the final shape of the parts. They may be used directly with little or no machining, making investment casting an advanced near-net shape forming process. Ancient Chinese artifacts such as the Prince Wu Ding, bronze censers, and bronze lions are all masterpieces of investment casting. Since its industrial application in the 1940s, investment casting has developed rapidly over the past half-century, particularly in Europe and America. Beyond aerospace and military applications, investment casting is used in almost all industrial sectors, especially electronics, petroleum, chemicals, energy, transportation, light industry, textiles, and pharmaceuticals.
