13.Recorder: paperless recorder / paper recorder; import / domestic

14.Electrical element: CHINT / Schneider / SIEMENS /ABB

●Technical feature of vacuum sintering furnace:

1.Adopting special furnace inner liner structure and heater arrangement, it has good uniformity of the furnace temperature.

2.Adopting special structure for the degreasing chamber, efficiency sealing, completely degreasing and no pollution to the inner element. 

3.Vacuum sintering furnace has flexible vacuum pumping, vacuum sintering, micro positive pressure sintering, partial pressure sintering, micro positive degreasing, and other functions;

4.Adopting the most advanced heat insulation structure and materials, good heat insulation performance of furnace liner, less heat, more than traditional design energy saving 25%.

5.Adopting touch screen operation, PLC centralized control, simple operation, high reliability.

6.Vacuum sintering furnace has the alarm function of ultra-temperature and ultra-voltage, mechanical and automatic for pressure protection action, interlocking functions, high safety equipment.

7.Vacuum sintering furnace has remote operation, remote fault diagnosis and remote software upgrades and other function.
