We can see all kinds of sculptures everywhere in our lives. Among them, cast bronze sculpture is a relatively common one. For cast bronze sculptures, people may still have a little knowledge of it. Let me introduce you to the common use of cast bronze sculptures. Materials and their production process. 1. Commonly used materials for copper casting sculptures 1. The characteristics of red copper are that the conductivity and plasticity of red copper are better, but the strength and hardness are lower. Red copper contains few other components and can generally be regarded as pure copper. 2. Brass Brass is an alloy composed of copper and zinc, which can be subdivided into simple brass and complex brass. In complex brass, the third component is named nickel brass and silicon brass. Wait, so brass is not pure copper. 3. Bronze bronze refers to copper-based alloys other than copper-nickel and copper-zinc alloys. The main varieties are tin bronze, aluminum bronze, and special bronze (also known as high copper alloy). 4 Cupronickel-nickel alloy refers to the copper-nickel alloy. It is a copper-based alloy with nickel as the main additive element. It is silver-white and has a metallic luster, hence the name cupronickel. Second, the production process of the cast bronze sculpture 1. The design of the sculpture is first of all The overall concept of the sculpture is designed to design the blueprint, and then the cast bronze sculpture is cast according to the pattern. 2. Making the clay draft and then making a rough model of the designed pattern with the clay draft, which is convenient for us to shape , If there is something wrong, we can change the clay sculpture. 3. There are two kinds of mold rebuilding molds: one is rebuilt with plaster if it is not too complicated, and the other is rebuilt with silica gel if it is complex. 4. Wax casting: Pour the melted paraffin into a plaster mold or silicone mold that has been made. After the paraffin cools, it will become a wax. 5. Shell making and mold reworking are divided into two types: One is small or complex ones. We should choose precision casting. The so-called precision manufacturing is to wrap the wax pattern made with fine quartz sand layer by layer, and then use high temperature to burn the paraffin wax inside the shell. The kind is resin sand box production. Sand box production is generally suitable for simple, flat reliefs, large copper coins, the back of copper Buddha statues, and smooth surfaces without much craftsmanship. 6. Casting high temperature turns copper into copper water into the finished shell. Or inside the sand box. 7. Polishing the riser and polishing. 8. Splicing the polished bronze sculptures together to form a complete whole. After this step is completed, we can basically see our cast bronze sculptures Approximately. 9. Clean up the welding joints and treat the welded parts of our spliced u200bu200bcopper sculptures to be exactly the same as our clay drafts. 10. The surface coloring reflects what period our copper sculptures reflect, and ancient ones are generally suitable Bronze is generally suitable for bronze in modern times. There are many modern bronze sculptures. There are gilded, gilded, and painted bronze sculptures. The above content is about bronze sculptures brought to you by Beijing sculpture manufacturers I hope to help you with the introduction of common materials and production processes.
