High Vacuum Sintering Furnace

Appointment

The sintering furnace at a high level of vacuum serves for sintering of tungsten alloy, magnets, cemented carbide, heavy alloys, etc.

Technical features

  1. The special design of the chamber and the ideal arrangement of heaters to obtain good temperature uniformity. 
  2. The vacuum sintering furnace has the functions of slow evacuation, sintering in vacuum, sintering at low pressure, sintering at partial pressure, and so on. 
  3. It uses advanced heat-insulating structures and materials, with good insulation and less heat absorption, saves more than 20% of energy compared to the traditional design. 
  4. Touch screen control, PLC centralized control, easy operation, high reliability. 
  5. The vacuum sintering furnace has alarm functions for pressure overload and overheating in the furnace, mechanical automatic pressure protection, blocking function, and other functions, high safety 
  6. It has the functions of remote control, emergency diagnostics and software updates.
