Abstract
Vacuum assisted molding apparatus provides reliable sealing about the mold cavity while minimizing the area of the plant floor space occupied by the mold. The apparatus includes an upper die, a lower die, a vacuum source, and a sealing assembly. The upper die includes a generally horizontal molding surface and vertically extending sides. The lower die includes a generally horizontal molding surface cooperating with the upper die to form a mold cavity. The sealing assembly is operable to create a vacuum surrounding the mold cavity.
