Investment Casting/Lost Wax Casting:

1.Mold and Pattern Making	A mold is built to customer-provided specifications. Cold wax is then injected into the mold to creat a wax pattern/prototype that will hold precise dimensional requirements in the final casting
2. Pattern Assembly	The wax patterns are assembled onto the sprue.
3. Dipping and Coating	Successive layers of ceramic and stucco are applied to the sprue assembly to form a hard shell.
4. De-waxing and Firing	The molds are flash-fired to remove the wax and sprue materials and then heated to 1800° and placed on a sand bed, ready for pouring
5. Casting	Molten metal, up to 3000°, is poured into the hollow mold and then cooled.
6. Knockout	The ceramic shell is broken off, and the individual castings are cut away.
7. Finishing	Excess metal is removed, surfaces are finished, and castings are heat treated.
8. Testing and Inspection	Castings undergo thorough testing and inspection to ensure that they meet dimensional tolerances and specifications.
9. Packing and Shipping	Castings are securely packaged for shipping to the customer.
