Casting method. A plaster or wax mold is made, and then molten copper is poured into the mold for casting. This method is suitable for the production of copper images with large volume and complex shape.
Large bronze statue production mainly has the following several methods:
1. Casting method. A plaster or wax mold is made, and then molten copper is poured into the mold for casting. This method is suitable for the production of copper images with large volume and complex shape. 2. Segmented casting method. The bronze model is divided into multiple parts, respectively, the production of plaster mold casting, and then through welding and other technologies to connect the various parts, assembled into a complete bronze. This method can reduce the load of the mold and avoid defects. 3. Forging method. At high temperature, the copper block is hammered with a hammer and gradually forged into the desired shape. This method is more expressive, but it is only suitable for smaller copper images, and there will be obvious hammer marks on the surface of the copper image. 4. Tin plating method. First, a gypsum prototype of a copper image is made, immersed in molten tin liquid, and a layer of tin is plated on the surface of the prototype. After the tin layer is cooled, the gypsum prototype is removed to obtain a hollow tin shell, and then copper liquid is injected into the tin shell. This method can produce a large bronze image with a strong sense of volume. 5. Welding method. Hundreds or thousands of small copper sheets are welded into the shape of a large copper figure. This method is highly expressive, but the technical requirements are high, and the welding quality is directly related to the texture of the copper image. The above methods can be used alone or in combination. The production of large bronze statues often requires the cooperation of various technologies to achieve good artistic effects.
