the production way for alumina ceramic beads

There are two ways for producing alumina ceramic beads,there are die press and injection moulding way. One is Die Pressing(also called dry press in china) This is by far the most widely used shaping technique for advanced ceramics Ceramic powder is contained within a hopper and fill the die cavity.The top punch of the die will come down and compress the Granular powder within the cavity to form the green body.Adjust mold and press machine is important. The other is Injection Moulding Low pressure injection moulding needs much lower cost tools.By this technology,complex shapes can be made....
