Vacuum Pressure Impregnation Furnace

This type of furnace is classified into two types: low temperature impregnation furnace and high temperature melting infiltration furnace. The low temperature impregnation furnace is mainly used for C/C, SiC and composite materials impregnation by asphalt, resin and polycarbosilane. The high temperature melting infiltration furnace is mainly used for graphite, ceramic and composite materials infiltration by molten aluminum alloy, copper alloy, titanium alloy and high temperature alloy.

Technical Features
1. The vacuum impregnation furnace has multiple stage safety protection.
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.

Optional Configuration of Vacuum Pressure Impregnation Furnace
1. Heater: Ni-Cr; Fe-Cr-Al-Nb, Sic rod, Graphite; CFC.
2. Process gas system: high pressure valve; manual value / auto value; foreign brand / Chinese brand.
3. Vacuum pump and gauge: foreign brand / Chinese brand.
4. HMI: Simulation screen / touch screen / industrial personal computer.
5. PLC: OMRON/Siemens.
6. Temperature controller: SHIMADEN/EUROTHERM.
7. Thermocouple: type C / type S / type K / type N.
8. Electric components: CHINT / Schneider / Siemens
