Process and system for pressure forming of a workpiece

A process for forming of a workpiece using a press comprising a pressure generator, a forming tool, and an elastically deformable element, wherein, during forming of the workpiece, the workpiece is arranged adjacent to the forming tool and the elastically deformable element and between one side of the elastically deformable element and a forming surface of the forming tool so that one side of the workpiece faces the elastically deformable element and another side of the workpiece faces the forming tool, wherein the forming tool is removably arranged in the press, and wherein the pressure generator is configured to exert a forming pressure of at least 5 MPa on the elastically deformable element and/or the forming tool so as to pressurize at least one of one side of the elastically deformable element opposite to the side of the elastically deformable element facing the workpiece, or a surface of the forming tool opposite to the forming surface, thereby causing the elastically deformable element to deform so as to cause the side of the workpiece facing the forming tool and the forming surface to be pressed against each other such that the workpiece is formed at least in part in accordance with the shape of the forming surface, the process comprising:

• arranging the forming tool and the work piece in a container comprising at least one opening, such that when the forming tool and the workpiece are arranged in the container, one side of the workpiece faces the forming tool and another side of the workpiece is directed towards the at least one opening;
• heating the workpiece and the forming tool, wherein the heating of the workpiece and the forming tool is carried out when the workpiece and the forming tool are in the container;
• arranging the container in the press such that the other side of the workpiece, which is directed towards the at least one opening, is facing the elastically deformable element;
• forming the workpiece using the press so as to obtain a formed workpiece, wherein the forming of the work piece using the press is carried out while the forming tool and the workpiece are in the container;
• wherein the heating of the workpiece and the forming tool is such that the temperature of at least one of the workpiece or the forming tool during the forming of the workpiece by way of the forming pressure is higher than the ambient temperature;
• the process further comprising:
• removing the container from the press with the forming tool and the formed workpiece still being in the container and with the elastically deformable element still being in the press.
