A vacuum chamber (1) for coating installations is provided, wherein the vacuum chamber (1) has a bottom plate (6) and a top plate (2), which are connected to each other by struts (4) running substantially perpendicularly to the bottom plate (6) and the top plate (2), wherein a plurality of openings (9) are defined by the bottom plate (6), the top plate (2) and the struts (4), and wherein at least a portion of a front edge (15') of the bottom plate (6) and a portion of the front edge (15) of the top plate (2) form together with two struts (4) a sealing area, running around one opening (9) of the multiplicity of openings (9), for an insert plate (8) that can be inserted into the opening (9). In addition, a method for producing a vacuum chamber (1) for coating installations is provided, comprising the following steps: putting together a frame which has a bottom plate (6), a top plate (2) and struts (4), which connect the bottom plate (6) and the top plate (2), and welding the bottom plate (6) and the top plate (2) to the struts (4).

L'invention concerne une chambre à vide (1) pour des installations de revêtement, la chambre à vide (1) présentant une plaque de base (6) et une plaque de couvercle (2), reliées l'une à l'autre par des étais (4) s'étendant de manière sensiblement perpendiculaire à la plaque de base (6) et à la plaque de couvercle (2), une pluralité d'ouvertures (9) étant délimitées par la plaque de base (6), la plaque de couvercle (2) et les étais (4). Au moins une section d'un bord frontal (15') de la plaque de base (6) et une section d'un bord frontal (15) de la plaque de couvercle (2) forment, conjointement à deux étais (4), une surface d'étanchéité circulaire autour d'une ouverture (9) de la pluralité d'ouvertures (9) pour une plaque d'insertion (8) pouvant être insérée dans l'ouverture (9). En outre, l'invention concerne un procédé de fabrication d'une chambre à vide (1) pour des installations de revêtement, consistant à : assembler un cadre présentant une plaque de base (6), une plaque de couvercle (2) et des étais (4) reliant la plaque de base (6) et la plaque de couvercle (2), et à souder la plaque de base (6) et la plaque de couvercle (2) aux étais (4).
