精密鑄造是用精密的造型方法獲得精確鑄件工藝的總稱。它包括熔模鑄造、陶瓷型鑄造、金屬型鑄造、壓力鑄造、消失模鑄造。其中較為常用的是熔摸鑄造:選用適宜的熔模材料製造熔模;在熔模上重複沾塗料與撒砂工序,硬化型殼及幹燥;再將內部的熔模溶化掉,獲得型腔;焙燒型殼以獲得足夠的強度,燒掉殘餘的熔模材料,;澆注所需要的金屬材料;脫殼後清砂,從而獲得高精度的成品。根據產品需要或進行熱處理與冷加工。 Precision casting is a general term for precise casting process with precision modeling method. It includes investment casting, ceramic mold casting, metal mold casting, pressure casting and lost foam casting. The more commonly used is fug casting: the choice of suitable melt mold material to make molten mold; duplication of coating and sand casting process, hardened shell and drying on the melt mold; then dissolve the internal molten mold to obtain the cavity; the calcined shell to get enough strength and burn the residual melt material, and the metal material needed to cast. Material; after shelling, remove sand so as to obtain high-precision finished products. Heat treatment and cold working according to product needs. 精密鑄造又叫失蠟鑄造,它的產品精密、複雜、接近於零件最後形狀,可不加工或很少加工就直接使用,故熔模鑄造是一種近淨形成形的先進工藝。 Precision casting is also called wax loss casting. Its products are precise, complex and close to the final shape of the parts. It can be used directly without processing or processing. Therefore, the mold casting is an advanced process of near net formation. 我國古代:王子午鼎、銅禁、銅獅等等,都是熔模鑄造的傑作。自20世紀40年代熔模鑄造用於工業生產後,半個世紀中一直以較快的速度發展著。特別是歐美國家發展迅速。現在熔模鑄造用於航空、兵器部門外,幾乎應用於所有工業部門,特別是電子、石油、化工、能源、交通運輸、輕工、紡織、製藥、醫療器械、泵和閥等部門。近幾年我國發展也迅速。 In ancient China: Prince Wu Ding, bronze prohibition, bronze lion and so on are all masterpieces of investment casting. Since the investment casting was used in industrial production in 1940s, it has been developing at a faster pace in the past half century. In particular, the European and American countries have developed rapidly. Now, the mold casting is used outside the air and weapons department, and is almost used in all industrial sectors, especially electronics, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, pumps, valves and other departments. China has developed rapidly in recent years.
