Membrane device for manufacturing crash pad for vehicle including real wood sheet and method of manufacturing crash pad for vehicle including real wood sheet using membrane device

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, the vacuum device main body comprising a plurality of wood seating pins that are movable upward or downward to seat the real wood sheet;
• a cover configured to be in an open state, in which the cover is open to expose the vacuum device main body, and a closed state, in which the cover is closed on the vacuum device main body, to define a vacuum space together with the vacuum device main body in the closed state, the cover including a silicone film disposed along an inside surface thereof;
• a vacuum module configured to suck air in the vacuum device main body through the vacuum holes;
• and
• a control unit configured to compress the real wood sheet and the core with the silicone film, 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 in the closed state, 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.
