What is Investment casting Door Hinges?
A door hinge made from investment casting process would likely be a high-quality door hinge, fine detail, and high strength. this process allows for the production of complex shapes that might be difficult or impossible to achieve through other manufacturing methods, such as stamping and bending process and the material can be customized to meet a specified requirement.
Such casting door hinges would typically be durable, with smooth surfaces and tight tolerances, making them suitable for applications where precision and reliability are essential, such as in high-end furniture, architectural applications, advanced door or window hardware or specialized industrial equipment where smooth operation and longevity are crucial.

Production process introduce
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

You can find our contact info for further communication in “Contact US” column.
The 2&3D drawing format can be PDF, STEP, DWG, DXF and soon, can be sent via email. Wechat, WhatsApp, link.
After clear the demand of customer, we can send you the quotation with PDF format for documentation.
For requirements for confidentiality of drawings, we can signed the NDA before you send drawing.
The feasibility study of drawing is most key point to ensure the part can be fully meet drawing specifications, which is include material, dimension, surface treatment, and testing request.
