Introduction of technological characteristics and process flow of bronze carving

? In the city where we live now, we can always see bronze sculptures on many occasions. It stands in every corner of the city like a frozen picture. Yes, bronze carvings are not only exquisite, but also unique in style and have high appreciation value. But what do you know about bronze carvings? Do you really know the craft of bronze carving? Don't worry, if you don't know the answer to the above question, Bian Xiao will answer it for you.

Technological characteristics and process of bronze carving.

Copper casting process

When it comes to bronze carving, it's very learned. In modern bronze carving, according to the way of casting copper, there are mainly casting copper carving and forging copper carving. For cast copper sculpture, it mainly uses a kind of high-temperature resistant mold, which is called refractory gypsum mold and sand mold. Some molds are divided into inner and outer layers, so that we can pour copper water into the mold from the skylight and finally cool it for a few days. The products made by copper casting process are strong and corrosion-resistant, and their service life is longer than other processes. The disadvantage is that they are too heavy and expensive.

Copper forging process

The process of forging copper is to make a mold first and then fix it in a certain position with special glue. When we heat the copper plate, we will find that the texture of the copper plate becomes soft. At this time, we will beat it with a hammer first, then shape it, then beat it, and then it can be shaped after repeated times. If the copper plate is heated again before forming, it can be forged again, but it is best not to forge for more than three times. Finally, it is soaked in copper sulfate when it is formed, so that we can get our own satisfactory works of art.

Key points of modern commercial copper sculpture technology

First of all, we ask customers to confirm or provide reference patterns for sculpture, and then let clay sculptors shape clay models according to customers' requirements. When the clay model is confirmed by the customer, we will turn over the model, start pouring the wax prototype fetal membrane, and finally bake the shell to dewax. At this point, we can start firing copper liquid. When the copper liquid cools, we can break the mold shell, and then we can see the finished copper.

Having said that, I believe everyone has a very clear understanding of the technological characteristics and technology of bronze carving. You know, in the actual production process, bronze carvings must go through 20 essential processes before they can be finally delivered for use. This requirement is not only the inheritance of traditional handicraft production, but also the secret of modern precision casting technology.
