Abstract
A plastic pallet has a twin sheet thermoformed upper deck reinforced with a tubular metal substrate. Injection molded plastic octagonal posts have support member walls which are positioned beneath reinforced portions of the top deck. The posts also have a sleeve with a central bolt hole which is parallel to the support member walls. A twin sheet thermoformed lower deck is spaced from the upper deck by the posts and receives the posts in recessed pockets. Plastic bolts are inserted through the top deck, each post, and the bottom deck and are held in place by plastic T-nuts. A sawtooth parting line in the twin-sheet thermoforming molds provide accurate alignment and molding of the pallet parts.
