Wax patterns of desired castings are produced by injection molding machine.
The wax pattern attached to a runner.
The shell is built by dipping the wax assembly in a liquid ceramic slurry and then into a fine sand.
After the ceramic is dry, the wax is melted out, creating cavity within the shell.
The shell is filled with molten by gravity pouring.
When the metal has cooled the ceramic shell is broken off by vibration.
The parts are cut off from the central runner using a saw.
After appearance inspection the casting is moved to machining process.
