    Gas Pressure Sintering Furnace

    A gas sintering furnace is used for vacuum sintering and sintering of Sic, Si3N4 and ceramic products under pressure. 


    1. This horizontal sintering furnace is equipped with a heating zone and a specially designed heating element to ensure good temperature uniformity. 
    2. It is a completely sealed muffle furnace to completely remove the binder and prevent contamination of the internal components. 
    3. The gas pressure sintering furnace has the functions of slow sintering in vacuum, sintering under positive pressure, sintering in medium vacuum, sintering under pressure, removing the binder under negative pressure and removing the binder under positive pressure. 
    4.  Advanced thermal insulation materials are used to provide insulation. 
    5. The horizontal sintering furnace is equipped with a touch screen and PLC. 
    6.  Equipment safety is ensured thanks to the alarm functions at overpressure and overheating of the furnace, mechanical automatic protection against overpressure and blocking. 
    7. The gas pressure sintering furnace has the functions of remote control, remote fault diagnosis and remote software update.
