The material of the lost wax casting method is made of refractory slurry (such as silicic acid or silicone rubber), binder and other materials to make slurry liquid and mix with zircon sand and mulgrain sand are sequentially covered in the wax tree outside after repeating several times of dipping slurry, fluid sand and drying to form a layer of similar ceramic shell, after the formation of the so-called ceramic shell mold, so casting alloy steel, super alloy and other high-temperature high-precision casting method, known as ceramic shell mold lost wax casting method.
