Abstract: A system for manufacturing foamed plastics laminated panels at a high volume is disclosed. Press modules include a pair of opposed spaced open frame members with longitudinal raised sections attached to perpendicular supports. The open frame members move relative to one another, support respective panel outer skin layers; and recieve therebetween edge sealing members of a predetermined thickness. A spacing between the open frame members and a hinge is adjustable to move a first open frame member relative to a second frame member. Clamps retain the open frame members in a predetermined space relationship, and when actuated, forms a mould cavity defined by the outer skin layers and edge sealing members supported by the open frame members. An inlet introduces an a liquid foamable plastics material into the moulded cavity, and a delivery system delivers liquid reactants in predetermined proportions to a selected mould cavity formed in a selected press module.
