Investment Casting/Lost Wax Casting:
|
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 |
|
Pattern Assembly |
The wax patterns are assembled onto the sprue. |
|
Dipping and Coating |
Successive layers of ceramic and stucco are applied to the sprue assembly to form a hard shell. |
|
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 |
|
Casting |
Molten metal, up to 3000°, is poured into the hollow mold and then cooled. |
|
Knockout |
The ceramic shell is broken off, and the individual castings are cut away. |
|
Finishing |
Excess metal is removed, surfaces are finished, and castings are heat treated. |
|
Testing and Inspection |
Castings undergo thorough testing and inspection to ensure that they meet dimensional tolerances and specifications. |
|
Packing and Shipping |
Castings are securely packaged for shipping to the customer. |
