Investment Casting Temperature Sensor Boss

1. Tooling Build

Design and building a metal die from Aluminum

2. Wax Injection

Injecting melted wax under high pressure into the cavity to get a pattern that replicates the finished part geometry

3. Wax Pattern Assembly

The wax patterns are assembled onto runners and into a finished tree which is ready to be dipped.

4. Slurry Coating

The assembly is then dipped into a high-grade ceramic slurry to build a ceramic shell around the wax tree.

5. Ceramic Shell build & Dry the shell

After the slurry coating is done, particles of sand are dropped onto the surface of the wet tree assembly. This helps to thicken and strengthen the layer of coating on the wax assembly surface, repeat 5-6 times.

6. De-waxing

Send the shell into pre-heating oven and then the wax inside the newly built shell is now removed. Dewaxing is done using a steam-dewaxing autoclave or flash fire furnace.

7. Melting & Pouring & cooling

Now the desired molten metal is poured into the pre-heated empty mold cavity, The mold then sits to allow the molten metal to cool and solidify which then becomes the final casting.

8. Shell Removal

The shell material is then removed through processes hammer knockout, vibration, and steel grit blasting

9. Cut-off

The finished parts are then cut free from the gating and runner system.

10. Grinding pouring gate

The ingate which remained after the sawing process, is grinded from the casting.

11. Final inspection

Once the finishing operations are done, the parts are inspected for surface and sub-surface defects.

12. Packaging & Delivery

For oversea shipping, we packaging with standard wooden pallet with size limited 1200*800mm
