Preparation process of alumina ceramic products

  • Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.

  • Isostatic pressing: During the isostatic pressing procedure, binders are blended with the ceramic powder. As a result of this process, the powder transforms into freely flowing granules that can effortlessly fill the molds.

  • Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.

Alumina Ceramic Delivery

▶Transportation methods: International express door-to-door service (small-volume goods), sea transportation ( large-volume goods), and railway transportation.

 ▶For goods requiring customs declaration, we will prepare complete customs declaration documents in advance to help customers clear customs quickly.

 ▶If you have special requirements for packaging, you can communicate with us in advance.
