The key of jewelry oil pressure technology

Hydraulic oil should be filtered, cleaned, dried and free of impurities before it can be injected into the mechanism for use. It is forbidden to mix different grades of hydraulic oil.

Gold oil pressure is oil pressure gold, oil pressure and pouring are different production processes, and have nothing to do with color. This is a process of making gold products.

The work of the oil pressure department is the same as that of the material preparation department, which is the initial form of processing products, that is, processing semi-finished products, but the oil pressure department is aimed at rings, bracelets, pendants, gold bars and other products. Due to the plastic deformation of the surface metal by oil pressure, the surface structure is cold hardened, the grains are refined, a dense fibrous structure is formed, and a residual stress layer is formed, so that the hardness and strength are improved, thereby improving the wear resistance, corrosion resistance and compatibility of the workpiece surface.
