铜雕的铸造方法主要有两种，即失蜡和模具法。
There are two main casting methods of copper carving, namely, wax loss and mold method.
失蜡法：用蜡制成模，外敷造型材料，成为整体铸型。
Wax loss method: the mold is made of wax, and the molding materials are applied externally to form an integral mold.
模具法：运用广泛，大型铜雕一般都要经过分件浇铸，然后衔接成一个整体。
Mold method: it is widely used. Large copper carvings are usually cast in pieces and then connected into a whole.
熔铜法：运用无模可控熔铸工艺，“无模”使铜液自然流畅而解形；“可控”使铜液在艺术家掌控中熔意。
Copper melting method: using the mold free controllable casting process, "mold free" makes the copper melt naturally and smoothly; and "controllable" makes the copper melt under the control of the artist.
