Apparatus, useful for sintering product, comprises construction element and substrate having pressing unit that comprises table and stamp, where press stamp comprises pressure body coupled to heating device such that pressure body expands

摘要

The apparatus comprises a construction element and a substrate having a pressing unit that comprises a press table (4) and a press stamp (3). The press stamp comprises a pressure body, which is coupled to a heating device such that the pressure body expands when a temperature increase so that pressure is applied to a sinterable product (2) located between the press table and the press stamp. The pressure body is made of a material having a linear expansion coefficient of 20x 10 -> 6>/K at 20[deg] C, and is coupled to a cooling device. The press stamp comprises a transducer (9). The apparatus comprises a construction element and a substrate having a pressing unit that comprises a press table (4) and a press stamp (3). The press stamp comprises a pressure body, which is coupled to a heating device such that the pressure body expands when a temperature increase so that pressure is applied to a sinterable product (2) located between the press table and the press stamp. The pressure body is made of a material having a linear expansion coefficient of 20x 10 -> 6>/K at 20[deg] C, and is coupled to a cooling device. The press stamp comprises a transducer (9) for applying force to the press stamp, a fixed support (12), a contact body, and pressure elements, a removable leveling body provided on the press table, and a conveyor for automatically conveying the sintered product. The apparatus further comprises a control unit for controlling the temperature of the pressure body based on the a signal of the force transducer, a unit for placing a separating film between the press stamp and the sintered product, a press-roll assembly, and a heatable work piece carrier. The pressure body is arranged between the support and the contact body. The conveyor includes a link chain, a stainless steel band or a linear transfer system. The press table is formed with a heating unit. The press-roll assembly comprises press rolls arranged in a plane, and is arranged in a conveying direction so that the pressure is applied to the work piece carrier located between the press table and the sinterable product. An independent claim is included for a method for sintering a product.
