Lost Wax Casting In Action ! - Video

The video shows the investment casting process, also known as lost-wax casting. A worker in aluminized heat-resistant protective suit takes out a glowing ceramic shell mold assembly from the high-temperature burnout furnace. This ceramic mold has already been baked at extreme heat, all wax patterns inside burned out. The preheated hot shell prevents cracking from thermal shock when molten metal pours in. The worker places the red-hot mold at the pouring station. Another operator holds a crucible with liquid metal and pours molten metal into the preheated ceramic mold. After cooling, workers break off the ceramic shell to get finished metal castings. This process can produce complex, high-precision metal parts. This is high-risk industrial operation done by trained professionals.
