  • Vacuum chamber on a frame basis for coating installations
    Patent number: 8104421
    Abstract: The present invention relates to a vacuum chamber and to its production. According to the invention, the vacuum chamber comprises a frame into which insert plates are placed. The insert plates form together with the frame a closed space in which a vacuum can be created. Preferably, the shell of the frame is extracted from an integrally formed metal piece, with a large portion of material being removed, leading to openings for the insert plates to be created. This has among others the advantage that no welding seams are necessary where the individual plates are inserted.
