The Silica Sol Casting Process
1. Pattern Make: Precision wax patterns are produced using injection molding machine.
4. Stucco Application: Refractory materials are applied between layers to enhance shell strength.
5. Dewaxing: The assembly is heated to remove the wax pattern, leaving a hollow ceramic mold.
6. Roasting: The ceramic shell is fired at high temperatures to achieve final strength.
7. Casting: Molten metal is poured into the prepared mold.
8. Shell Removal: After cooling, the ceramic shell is broken away to reveal the cast part.
