The metal forging process is one of the traditional metal processes in China. The craftsmen cut gold, silver, copper, and other metal materials into circular plates, and then utilized the ductility of the metal to anneal and forge them finally they were shaped and forged into the metalware.
The development of the metal forging process until the Tang Dynasty has reached an unprecedented height in terms of the shape of the metalware, the fineness of the craftsmanship, and the gorgeous decoration of the metalware. The inherited metal forging process is rare among Han folk. The main tools of the metal forging process are hammers with different shapes and sizes, forming anvils, smelters, hand pliers, various chisels, vices, spray guns, welding guns, crucibles, etc. In addition, there are casting steel molds for various purposes, all sorts of files, metal scissors of different sizes, etc.
Now the hot metal forging process has made great progress based on inheriting the traditional forging process, which is mainly reflected in the changes in the process caused by the improvement of the production tools, such as the craftsmen which are from Bai nationality in Yunnan, China has learned to open metal plates with the air hammers, shape metal bars, and roll metal sheets with large calendars.
According to the size of the metalware, it is necessary to cut a round metal plate suitable for it and make it into the preliminary shape of the metalware by forging. That is, place the round metal plate on the anvil, adjust the forging strength and inclination angle, and evenly forge every part of the round metal plate while turning.
If some places are over forged, the thickness of the metal plate will be uneven, and even cracking may occur. Other places may also crack and roll up, and the edges of the metalware may also be uneven. In the process of metal forging, attention should also be paid to annealing to soften the hardness and prevent cracking during re-forging.
After the preliminary shape of the metalware is formed, the next step is with the anvils of different specifications to forge specific shape transitions carefully. The forming is to forge with a hammer while turning the metalware. Different shapes of the metalware use different hammer, forged ak trunnion and anvil. Some hammers are used to form, some are used to hammer the turning surface, and some are used for detail finishing.
The processing effect mainly refers to the process treatment of the surface of the metalware including chiseling and scribing, decoration of traditional patterns, embossed effect, etc. Some metalwares use the texture effect of forging and hammering, which is natural and simple and has a strong and rough natural flavor. After the process effect is completed, in the overall design, the accessories of the metalware such as cover, handle, mouth, etc. are produced and welded.
Due to the utility of the ductility of metal, the metal forging process has a full shape and tension with custom forged parts, which is not only practical, but also beautiful, and has more vitality in artistic expression. Similarly, decorative patterns are also an important part of the metal forging process.
The development of forging products and the constant changes of decorative patterns are always influenced by customs and culture. Therefore, decorative patterns on metal forging products are also regarded as living fossils and are important for studying the development of national culture.
