Hot press molding can obtain high dense special products whose density is close to the theoretical value. Hihg temperature and pressure promote the contact and diffusion of mud particles, which can reduce the sintering temperature and sintering time.

The hot press molding machines include hydraulic pressing equipment and graphite models. Graphite model can withstand high temperatures and withstand high pressure at high temperature. The mold can be heated with Induction coils or by resistance heating. Generally it is heated in a high-frequency induction hot furnace.

Mud is loaded into the mold and then hot pressed at 1850 ° C or higher under 25-50MPa.
