Zirconia ceramic hot pressure injection molding

Hot press injection molding is to mix ceramic powder with binder (paraffin) at a relatively high temperature (60~100 ° C) to obtain a slurry for hot die casting, and the slurry is injected into the metal mold under the action of compressed air to keep the Press cooling, demoulding to obtain a wax blank, the wax blank is dewaxed under the protection of inert powder to obtain a green body, and the green body is sintered at high temperature to become porcelain. The green body of hot press injection molding has accurate size, uniform internal structure, less mold wear, high production efficiency, and is suitable for various raw materials. The temperature of the wax slurry and the mold needs to be strictly controlled, otherwise it will cause under injection or deformation, so it is not suitable for manufacturing large parts, and the two-step firing process is complicated and energy consumption is high.
