Five Steps of Manufacturing
Step1: Powder Preparation
Applying a hydrothermal method, ceramic powder is mixed with an additive, followed with precipitation, alcoholysis, low-temperature hydrolysis, blending, fracturing and prilling.
Step 2: Forming
General forming techniques include pressing, extrusion, injection molding, dry pressing, gelling and casting.
The formed part is sent into a high temperature furnace where it’s kept for a fixed time to achieve a dense, advanced technical ceramic. Before, and sometimes during, this stage, any organic additives remaining need to be removed.
During this part of the process, thermal debinding, solvent debinding and hot isostatic pressing techniques will also be applied.
This machining process involve three stages:
- Flat grinding / rough blank processing
- CNC machining
- Finishing / polishing
Step 5: Cleaning and Inspection
Post-processing includes surface treatment such as sandblasting, PVD, laser printing, which is completed with cleaning of parts.
A final inspection is conducted to detect cracks or flaws, and to ensure the ceramic part is delivered with zero defects.
