Sintering furnace for components consisting of a sintering material, in particular for dental components, and a method for sintering such components

A method for sintering components consisting of a sintering material, in particular dental components and a sintering furnace, comprising the following steps:

• a) opening a wall section of a furnace chamber with a preheated furnace chamber when the furnace heater is turned on;
• b) loading the furnace chamber, in particular by bringing a component to be sintered that is placed on a seat outside of the furnace chamber up to the open wall section;
• c) closing the furnace chamber;
• d) heating the furnace chamber up to a holding temperature TH over a time period HU2;
• e) maintaining the holding temperature over a time period H;
• f) opening the furnace chamber, either when the furnace heater is turned off or when the furnace heater is turned on;
• g) for a first cooling stage, bringing the component with the seat into a heated, first cooling zone where it remains for a cooling period CD1;
• i) removing the component from the seat, bringing the component into an additional cooling zone for the additional cooling stage by placing it on a base that is basically at room temperature, and waiting for a cooling period CD3. j) wherein
• -steps a)-c) are performed for a time period L of at least 2 seconds and at most 2 minutes and preferably 1 minute;
• -step d) is performed for the maximum time period HU2 of 8 minutes, and preferably 4-5 minutes;
• -step e) is performed for the time period H of 15 minutes, and preferably 4-8 minutes;
• -steps f) and g) are performed for the cooling time CD1 of at least 0.5 minutes but at most 5 minutes;
• -step h) is performed for a cooling time CD3 of at least 0.5 minutes, but at most, 10 minutes.
