Vacuum Pressure Impregnation Furnace

  • Vacuum pressure impregnation furnace has low temperature impregnation type and high temperature melting infiltration type. Low temperature impregnation is mainly used for impregnation of pitch and resin to C/C, Sic materials. High temperature melting infiltration of copper and aluminum to graphite and ceramic.

Description

Technical Features
1. The vacuum impregnation furnace has multiple stage safety protection, main chamber can meet over 6000 times changing stress working condition.
2. Locking ring is hydraulic driving with mechanical limit.
3. Door open is hydraulic manual open or auto open, which is simple to operate.
4. Low temperature impregnation furnace has single chamber and twin chamber option.
5. High temperature melting infiltration furnace can continuous working to improve the production efficiency.
