Details of VHP-D Silicon nitride ceramic vacuum hot press Furnace
Vacuum hot pressure furnace is a complete set of equipment for hot pressing materials under vacuum (or other atmosphere) conditions. It mainly adopts resistance heating and pressurizes the press head driven by the oil cylinder. The equipment combines vacuum/atmosphere, hot pressing forming and high temperature sintering. The equipment is suitable for high temperature hot forming of silicon nitride ceramics and other ceramic materials.
The "double chamber" vacuum hot press furnace adopts two presses respectively to pressure two parallel furnace bodies, and uses a set of vacuum system, hydraulic system and control system to improve the efficiency and reduce the cost.
