Investment casting process
|
1. Mould Designing Strictly making 3D model based on customer's drawing dimensions, and mastered the contractibility rate for all types of material. |
2. Wax Injection Wax design of the desired castings are produced by injection molding. These designs are called patterns |
| 3. Assembly The patterns are attached to a central wax stick, called a sprue, to form a casting cluster or assembly. |
4. Shell Building
The shell is built by immersing the assembly in a liquid ceramic slurry and then into
a bed of extremely fine sand. Up to eight layers may be applied in this manner.
|
| 5. Dewax At this point, all of the residual pattern and gating material is removed, and the ceramic mold remains. The mold is then preheated to a specific temperature and filled with molten metal, creating the metal casting |
6. Mould Shell Roast:
This process is to put the lost-wax shell into the roast furnace and make them harder. Heating the Mould shell before casting is also to ensure the better products surface texture.
|
|
7. Smelting the Liquid Steel:
Allocate the chemical composition and sampling before steel casting.
|
8.Spectrochemistry Analysis Inspection on materials by spectrometer testing. |
| 9. Pouring In the conventional process, the shell is filled with molten metal by gravity pouring. |
10. Cut Off The parts are cut away from the central sprue using a high speed friction saw. |
|
11.Heat Treating
Carbon steel and low-alloy steel need normalizing and temper, oil-quenching, water-quenching and so on. We can set out different heat treatment method as per different requirement from customers.
|
12. Grinding
Grinding is to modify the out of flatness on casting head after casting cuttig and to modify the burring and splashings in the process of casting cycle. |
