Customizable Gas Pressure Sintering Furnace with Positive-Negative Dewaxing Function

  Gas Pressure Sintering Furnace with Positive-Negative Dewaxing Function

Positive pressure

Positive pressure leak detection of dewaxing system: low-pressure nitrogen is filled into the dewaxing tank through the busbar, and the relative pressure transmitter of the dewaxing system detects the pressure in the tank. The user can set the upper and lower pressure limits (both in mbar). When the pressure in the tank reaches the upper limit, the inflation is stopped, and a period of time is waited (this time can be set, the default is 2 minutes). After the pressure in the tank tends to stabilize, the leak detection countdown begins.

Vacuum dewaxing function

-Setting dewaxing technical curve: Remove the binder through setting temperature curve, Argon or Nitrogen as medium, the binders collected in dewax collection tank,gas will be pumped out by pumps.

-Automatic dewaxing at wax line temperature: Set the negative pressure dewaxing curve to increase the temperature. Low-pressure argon or nitrogen enters the furnace at a set flow rate through the mass flow meter. At this time, the insulation door and the inner door are closed, the mold temperature controller starts automatically, and the front pump starts. The dewaxing time is determined by the wax line temperature. The user can set the upper and lower limits of the wax line temperature. When the wax line temperature is greater than the upper limit, the program is paused and the equipment is in a heat preservation state. When the wax line temperature is less than the lower limit, the program continues to run. This process guarantees the uniform removal of the molding agent to the maximum extent.
