Advanced Production Process

1. Raw Material Preparation：Selected high-purity alumina powder, undergoes strict composition testing and particle size control to ensure compliance with medical-grade material standards.
2. Forming Process：Adopt isostatic pressing, injection molding and other processes, select the appropriate forming method according to the shape and size of the valve plate for hemodialysis equipment.
3. Drying Treatment：The formed green body is slowly dried to remove moisture and prevent cracking and deformation during sintering.
4. High-temperature Sintering：Sintered in a high-temperature furnace at 1600-1800°C to form a firm bond between alumina particles and obtain a high-density ceramic body with excellent corrosion resistance.
5. Precision Machining：The sintered ceramic valve plate is precision machined and surface treated to ensure dimensional accuracy and surface quality meet the requirements of hemodialysis equipment.
