Problems solved by technology

[0002] Molds are various molds and tools used in industrial production for blow molding, injection molding, extrusion or forging molding, smelting and other methods to obtain the required products. With the explosive growth of the photovoltaic market, the demand for crucibles is also increasing. At the same time, the size of the crucible is getting larger and larger, and the manufacture of the crucible requires the use of molds, but the structure of the traditional crucible mold is complex, not resistant to high temperature, and has poor strength and is easy to damage
