How a vacuum press works?
The simplest type of vacuum press uses a sealable bag and some form of vacuum generator. By placing materials in the bag, sealing it and then sucking out most of the air, a pressure differential is created between the reduced pressure inside the bag and atmosphere on the outside.
What are vacuum presses used for?
The most common use for vacuum presses in the woodshop is to adhere wood veneers or laminates to a substrate, usually plywood. Rather than building a complex mechanical clamp that uses curved cauls to apply pressure to the center of a glue-up, a vacuum press just requires that the assembly be inserted in the bag.
