ABSTRACT:
A method of forming a twin sheet plastic pallet formed of an upper and a lower sheet and utilizing an upper male mold having downwardly extending leg protrusions and a lower female mold having complementary upwardly opening leg cavities. The method includes introducing the lower sheet between the spaced upper and lower molds, vacuum forming the lower sheet to the molding surfaces of the upper mold, vacuum forming the lower sheet to the molding surfaces of the lower mold, introducing the upper sheet between the spaced molds, vacuum forming the upper sheet to the molding surfaces of the upper mold, and bringing the upper and lower molds together with their leg portions in nested relation to fuse the upper and lower sheets together along their peripheries and at the interfaces their nested leg portions to form the final pallet.
