A device for dewaxing sintered material comprises a wax separator 16 connected between a sintering oven 1 and a device for moving fluids 22, preferably a pump, wherein the amount of fluid removed from the oven 1 is determined by a control system (26, Fig 2) in response to a interior oven pressure reading from a pressure measuring device 12. The wax separator 16 has an outlet 19 for wax condensate and may have a heater (31, Fig 6) controlled by a unit acting in response to readings from a temperature sensor. The separator 16 may be connected by a fluid line to a gas burn off device (29, Fig 3), the gas flow controlled by a valve (27, Fig 3) adjustable by the control system (26, Fig 2). Preferably, valves 14 and 23 are provided between the separator 16 and the sintering oven 1 and the pump 22 each being controlled by the control unit (26, Fig 2). The sintering oven 1 comprises a gas supply 10 to diffuse gas to its interior. A temperature measuring device 15 is provided to measure the temperature between the oven 1 and separator 16. |
