Depth analysis of all copper lamps-Sand-turning copper

As a salesman of all-copper lamps in snooker, I deeply understand that all-copper lamps are expensive; In the process, it is an unchangeable fact. It is also an indisputable fact that the price proportion of all-copper lamp materials is not as high as that of technological production, and then the materials and technologies are indispensable. Today, Xiao Bian will analyze the sand-turning copper process that will be used in the production of all copper lamps. Step 1: According to the physical objects or drawings of all-copper lamp fittings, the original master mold is carved with gypsum or other materials. In the second step, clay or chemical binder is mixed with carefully selected sand according to a certain proportion and then coated on the master mold. After the master mold is completely solidified, the master mold inside is taken out, all copper lamp cavity sand mold is obtained. The third step is to inject copper into the cavity sand mold after melting at high temperature, and remove the sand mold on the surface after the copper is completely solidified and cooled. You can get a matte copper fitting for a full copper lamp. Of course, this accessory also needs to go through the following processes such as polishing and polishing before it can be applied to the finished copper lamp. In the whole process of making sand-turning copper fittings for all copper lamps, several factors determine the quality of the whole sand-turning copper fittings. First, it is the carving level of the carving master. The finer the carving, the better the mother mold, and the better the copper lamp fittings made later. Second, the fineness of sand and its proportion of mixing with clay or binder are also decisive factors in determining the quality of the final copper lamp fittings. Third, the copper content of the copper used is also a key factor. The method of bonding sand is to make sand mold according to the all-copper lamp to be made, and then produce the required casting through this molding material. The price of many all-copper lamps on the market is uneven. The price of the same lamp varies from several hundred to several thousand. In addition to the material, the process and surface treatment used are also some very important contrast factors.
