Used in industrial valves, flow meters, pumps, disks, pipe fittings; various machines, internal combustion engines, engines, heat exchangers, impellers; construction, sanitary, door locks, marine hardware parts; pneumatic, electric, hydraulic tools, hand tools, stamping tool parts; auto, motorcycle, vehicle, bicycle, aerospace, needle car, textile machinery parts; medical, sports equipment, computer business machine parts and other industries.

The dewaxing process requires an aluminum mold. The wax is pressurized into an aluminum mold to make a wax embryo, which is a replica of the true shape of the product produced. For each casting process, this wax embryo must be manufactured first. Several wax embryos are composed into three strings, which are repeatedly immersed in mud (or stone mortar) repeatedly, embedded in the outer layer and dehumidified and dried, and the ceramic shell is made into 9mm. (5-7 layers) thick, then put this tree string into a high-temperature 140-160 ° C oven or high-pressure steam pot to dissolve wax embryos until it becomes a hollow pottery shell.

This hollow ceramic shell is sintered at 1000 ℃ -1150 ℃ according to different alloy materials. The molten metal is immediately cast into the ceramic shell. After cooling, the outer ceramic shell is broken, sandblasted and cleaned, and cut. Grinding and heat treatment. Finishing, machining, polishing, etc.
