Advanced Production Processes
- Raw material preparation: Selected high-purity alumina powder, after strict composition testing and particle size control to ensure stable quality of raw materials.
- Molding process: Isostatic pressure molding, extrusion molding or injection molding are used, and the appropriate molding method is selected according to the shape and size of the product.
- dry processing: The raw blanks after molding are dried slowly to remove moisture and prevent cracking and deformation during the sintering process.
- High temperature sintering: Sintered in a high temperature furnace at 1600-1800°C to form a strong bond between the alumina particles and obtain a high density ceramic body.
- precision machining: The sintered ceramic tubes are precision machined and surface treated to ensure that the dimensional accuracy and surface quality meet customer requirements.
