The earliest bronze sculptures in China can be traced back to the Shang and Zhou dynasties and have a history of several thousand years. With the development of modern science and technology, modern copper casting technology and craftsmanship are slightly different from the past. Every bronze sculpture needs to go through at least 8 complicated and strict processes. These crafts have both the traces of traditional handicrafts and the wonders of modern precision casting technology. So, what is the process of casting bronze sculptures? The process flow of bronze sculpture    1. Sculpture design is first of all about the overall conception of the sculpture, designing a drawing sample, and then casting the bronze sculpture according to the pattern. 2. Clay draft production According to the size of the design draft, the skeleton is built, the clay is shaped, and a rough model is made from the clay draft according to the pattern, which is convenient for finalization. The specific details and requirements can be detailed on the clay sculpture. This process requires Consider the degree of realization and the final overall effect.  3. There are three types of molds for remanufacturing: one is to rebuild the mold with gypsum if it is not too complicated; the other is to rebuild the mold with silica gel if it is complex; the other is to rebuild the mold with FRP. The specific mold to be used can be determined according to the specific situation, because each mold process and cost are not used, and the most important thing is the cost.   4. After the paraffin wax mold is rebuilt, the melted paraffin wax is poured into the plaster mold or silicone mold that has been made, and the paraffin wax becomes a wax mold after it cools and solidifies. 5. Shell making There are two types of shell making: one is small or complex, we should choose precision casting. The so-called precision production is to wrap the wax model made with fine quartz sand layer by layer, and then use high temperature. Burn the paraffin wax inside the shell. The other is resin sand box production. Sand box production is generally suitable for simple, flat relief, large copper coins, the back of copper Buddha statues, and smooth surfaces without much craftsmanship.   6. Casting high temperature to convert copper into copper water and pour it into the finished shell or sand box.  7. Polish the riser and polish.   8. Splicing puts the polished bronze sculptures together to form a complete whole.  9. Clean the weld joints and treat the spliced u200bu200bcopper carving welding parts, as close as possible to the design and manufacturing process requirements. 10. Color processing is based on the customer's requirements or the specific circumstances of the design sample, because the colors of different periods are different, the ancient ones are generally suitable for bronze and the modern ones are generally suitable for bronze, and there are many modern ones. Cast bronze figure sculptures, there are gilded ones There are also gilded ones and painted ones.  11. Oiling, sealing wax and sealing wax can keep our cast bronze sculptures up-to-date for a long time. Surface effect treatment and protection. (The effect required for the surface treatment of the product is usually divided into cold color and hot color, the specific color distinction and characteristics, and finally waxing protection and polishing)
