Vacuum hot press furnace is widely used for all kinds of composite materials, high conduct thermal material, SiC/Si3N4/B4C ceramic materials, copper base iron power materials, iron base materials, iron-copper base power materials shaping, densification. And the max sintering temperature can be 2500°C, such as the iron-copper base brake disc of the plane, bullet train brake-shoe, armor, armored car backplane, bullet against armor of the helicopter.
