Panel molding method and apparatus

摘要

A method and apparatus for molding panels, the apparatus including upper and lower mold dies, a sprayer that sprays resin onto the lower mold die, and a wiper seal ring that's disposed in a position to form a vacuum chamber between the upper and lower mold dies as the mold dies are moving together from an initial sealing position to a closed position. A vacuum source draws air from the vacuum chamber as the mold dies are closing. The vacuum draws trapped air from within the sprayed-on resin to provide a superior class-A surface.
