Wax reproduction
of the required castings are produced by
injection mold. |
|
 |
|
|
 |
The wax
patterns are assembled to a wax stick, to form a
casting cluster. |
|
|
|
|
 |
The shell
is built by liquid ceramic slurry.
Up to seven layers may be applied in this process. |
|
|
|
|
 |
When the
ceramic is dry out, the max is melted out by heating,
creating an empty shell mold. |
|
|
|
|
 |
In this
process, the shell is filled with melted metal.
Once the metal cools, the assembled cluster become one
solid casting. |
|
|
|
|
 |
When the
metal has cooled, the ceramic shell is broken off by
vibration machine. |
|
|
|
|
 |
| The parts
are cut off from the cluster by using a high speed saw. |
|
|
|
|
 |
| Using
3 process blasting equipments to clean remnant ceramic. |
|
|
|
|
 |
Pickling
is chemical treatment applied to the surface of stainless
steel to remove contaminants. |
|
|
|
|
 |
After
minor finishing operations, the metal castings--identical
to
the original wax patterns--are ready for machining. |
