  • Patent number: 10101088
    Abstract: The invention relates to a sintering furnace for components consisting of sintering material, especially dental components and in particular components consisting of ceramic, and a method for sintering such components. The sintering furnace 1 comprises a heatable furnace chamber 2 for the component 9 to be sintered, the furnace chamber 2 having a wall section 6 to be opened for inserting the component 9 to be sintered into the furnace chamber 2. Drive means 10 are provided for mechanized opening and closing of the wall section 6, and a control 11 is provided for the drive means 10 that has an actuation element 12 for the drive means 10. Furthermore, a heating device 5 for the furnace chamber 2 is provided, and the control 11 causes the furnace chamber 2 to be heated. Actuating the control element 12 triggers the loading sequence of the control 11, and the drive means 10 are automatically actuated by the control 11 corresponding to the loading sequence.
    Type: Grant

  • Patent number: 8401690
    Abstract: In a method for processing a blank (1), in which the blank (1) can be densely sintered with shrinkage following machining and machining of the blank (1) is carried out in a machining device (7) allowing for an individual scale-up factor (F) relevant to the blank (1) for compensating for the shrinkage occurring during dense sintering, a linear measurement of the blank (1) is performed in one or more of the dimensions length, width, and height for determining the scale-up factor (F), wherein the measured linear measure (1) bears a known relationship to the scale-up factor (F), the type of blank (1) being known. Linear measurement of the blank (1) can be carried out in the machining device (7).
