Vacuum molding is the process of using a vacuum to suck a pliable material into a specified shape. For example, the plastic hull in a boat is made when the warmed plastic is pliable (shape can be altered for useful purposes) and is sucked up against a form in the shape the designer wants the hull of the boat to be in. While the vacuum holds the reshaped plastic hull against the form, the plastic cools and holds the new shape.
