Membrane device for manufacturing crash pad for vehicle including real wood sheet

A membrane device for manufacturing a crash pad for a vehicle including a real wood sheet, the membrane device comprising:

• a vacuum device main body having a plurality of vacuum holes and configured such that the real wood sheet to be temporarily attached to a core is mounted in the vacuum device main body;
• a cover having a silicone film and configured to define a vacuum space together with the vacuum device main body;
• a vacuum module comprising at least one vacuum pump and a manifold fluidly connected to the vacuum holes;
• and
• a control unit configured to compress the real wood sheet and the core, which are temporarily attached and mounted on the vacuum device main body, for a preset time by sucking air in the vacuum space through the vacuum holes in a state in which the vacuum device main body is covered by the cover, the control unit being configured to remove the vacuum from the vacuum space by controlling the vacuum module so that the compressed real wood sheet is detached from the vacuum device main body,
• wherein the vacuum device main body defines an introduction space located below a fixing jig on which the core is mounted, and comprises sliders positioned on opposite sides of the fixing jig, the sliders being configured, after completion of a primary vacuum compressing process that compresses the real wood sheet against an exterior surface of the core, to move upward and wrap a remaining portion of the real wood sheet around an inner surface of the core when the remaining portion is drawn into the introduction space by a secondary vacuum process.
