商代铜器均采用合范方法铸造，范的多少则视器形而定。商代早期的铜爵是由2块腹范、1块□范、1块底范和1块芯座合范浇铸的，而商代晚期的铜爵则需用16块外范。商代中期除能够铸造大型器物外,已能用分铸的方法,将一些器物的附件预先铸好，再和主件铸接在一起，例如卣的提梁就是另行铸造的。 The bronze wares of the shang dynasty were cast in the method of fan, and the amount of fan was determined by the shape of the instrument. The copper viscount in the early shang dynasty was cast by two ventral fan, one piece, one bottom and one core, while the bronze marquis in the late shang dynasty needed 16 pieces. Shang dynasty medium-term except to casting large objects can have points of casting method, some implements cast ahead of attachment, them together again with the main pieces of casting, such as You girder is casting separately. 　　商代晚期铸造技术有更进一步的发展,如司母戊方鼎的鼎身和四足是整体铸造的,鼎耳则是在鼎身铸成后再在山刷房  保定强夯 卷扬式启闭机  保定网站制作 收费岛模具 遮阳网 麻绳其上安模、翻范、浇铸而成，根 Late shang dynasty casting technology have further development, such as SiMuWu square body and the four legs are integrally cast, ear is in again after body cast on them AnMo, van, casting and become, root 据其体积和重量估计，所需金属料当在1000公斤以上，冶铸时必须有较大的熔铜炉，且有可能采用经地槽流注的方法进行浇铸。 According to its size and weight, it is necessary to have a large melting copper furnace for metallurgical metallurgy, and it is possible to cast the cast in the way of geosyncline. 　　商代晚期还发展了铜镶玉的技术，例如妇好墓出土的玉援铜戈即是将玉戈援纳入铜内的陶范中铸成。藁城等地发现的铁刃铜钺也是采用这种技术铸成的。铭文 商代早期和中期的铜器上至今未见铭文。 Later in the shang dynasty, the technology of copper paneling, such as the jade aid copper, unearthed from the tomb of a woman, was cast in tao fan, which was incorporated into copper. The iron blade copper tomahawk found in the land of China is also cast in this technique. The inscriptions have not been found in the early and mid-stage copper wares of the shang dynasty
