Investment casting - making ceramic shells is an important step

Investment casting with ceramic shell is a common process in precision casting, and making ceramic shells is an important step in this process. Here is a brief introduction: 1.Wax pattern preparation: Melt wax and inject it into a metal mold according to the shape and size of the desired casting. After the wax solidifies, remove the wax pattern. 2.Coating with ceramic material: Dip the wax pattern into ceramic slurry to allow the ceramic material to adhere to the surface of the wax pattern. 3.Solidification of ceramic shell: Place the wax pattern coated with ceramic material in an oven to allow the ceramic material to solidify and form a ceramic shell. 4.Wax removal: Invert the solidified ceramic shell and melt the wax inside the shell with heat, leaving a cavity for the casting. 5.Sintering of ceramic shell: Put the ceramic shell without wax into a sintering furnace and heat it to a certain temperature to make it harder and more wear-resistant.
