How to cast copper castings
The process of casting copper castings mainly includes the following steps:
Plastic clay mold. First of all, you need to make a solid clay mold from clay according to the prototype of the bronze to be cast. On this clay model, the decorative pattern of the trunk needs to be carved.
copy the foreign model. In the process of making the outer model, it is first necessary to pat the evenly mixed soil into flat pieces, and then press it on the outside of the clay model, so that the decorative patterns on the clay model are printed on the pieces. After the clay piece is half-dried, it is cut into several pieces with a knife according to the ears, feet, pins, bottom, sides, corners or symmetrical points of the bronze ware. Two adjacent clay moldings need to be spliced with triangular tenons and mortises, and then dried or baked with low fire to trim the patterns on the inner surface of the moldings, so that the outer moldings are finished.
Make an internal model. The process of making the inner model is to scrape off a layer of clay mold used for making the outer model while wet, and the thickness of this layer is equivalent to the thickness of the cast bronze ware. After scraping, it is dried with fire to make the inner mold. If there is an inscription on the inner model, it needs to be engraved on the outer surface of the inner model.
He Fan. Invert the inner fan on the base, and then place the outer fan block around the inner fan. After the outer fan is closed, it needs a closed fan cover, and at least one pouring hole is left on the fan cover. 2
Casting. The molten bronze solution is injected along the pouring hole. After the copper liquid is cooled, the outer mold is broken, and the inner mold is taken out to obtain the bronze blank. After that, the blank needs to be polished and trimmed, and finally the casting process is completed.
In addition, there is the Tao Fan method, which is to copy the outer fan on the clay mold, and then combine the inner and outer fans for casting. This method is suitable for casting more complicated bronzes.
