Resistance heating vacuum hot pressing sintering furnace is the equipment for the hot-pressing sintering process. Vacuum hot pressing sintering is a certain vacuum high temperature environment, the sample imposed a certain pressure, so that the particles in the embryo body powder at high temperature, but also by the mechanical force, to promote the embryo body of different particles contact and diffusion, flow, so that the rearrangement of powder particles, slip occurs, a large accumulation gap is filled, stomatal is excluded, thereby enhancing the over-reaction and sample density.

Applications
The use of vacuum hot pressing sintering is a technological progress, mainly used in:
1. Tools such as diamond and cubic boron nitride products: alloy products; metal and ceramic powder high-speed steel products.
2. Electrical categories: soft magnetic, magnetic, high-temperature magnetic materials; ferrite, electrical contact materials, metal electric materials, electrical vacuum materials.
3. Diffusion welding technology research and development
4. Special materials: powder super-alloy, oxide dispersion strengthening materials, carbon boron, nitride dispersion strengthening materials, fiber reinforced materials, high purity heat-resistant metal (tantalum, niobium, molybdenum, tungsten, cymbals).
