What is lost wax casting?
Lost wax casting is also called precision casting. Artwork is also used in this way. Most ancient works of art were this way.
Materials: wax, shell refractory (such as quartz sand, bauxite, etc.), binder (such as water glass, ethyl silicate, silica sol, etc.)
The first step is the design process.
Step 2: make the mold.
Step 3: wax the mold and remove the wax. The shape of the wax piece is the casting after casting.
Step 4. Repair the wax.
Step 5: apply the wax parts to the pouring system.
Step 6: shell. First, put the good wax parts into the slurry, dip the paste, and then remove the wax pieces into the sand, so that the surface of the wax will be coated with a layer of sand. To dry. After this layer is dry, continue such procedures, generally five to six levels. The last layer is only the paste, not the sand.
Step 7: dewaxing. When the shell is made, the surface of the wax is not completely covered by the sand, but a part is exposed at the top of the water. When the wax is placed in the device, the wax is heated and the wax is melted and the wax is released.
Step 8: pour. You need to preheat the shell when pouring.
Step 9: vibration shell
