ABSTRACT:
A method is provided for forming a pallet including thermoforming a pair of plastic sheets and then fusing the two sheets together to form the pallet. One of the two sheets is thermoformed to provide a series of pin assemblies with each pin assembly including a plurality of hollow pin portions extending outwardly. The second sheet is thermoformed to provide a series of leg portions that define a corresponding series of grooves in the sheet, each groove corresponding to a respective pin assembly of the first sheet. The first sheet is assembled with the second sheet such that each pin assembly of the first sheet rests nestingly within the respective groove of the second sheet and then the material of the pin assemblies are fused to the material of the respective grooves. Web portions of the first sheet interconnect adjacent pin portions and are formed as folds extending outwardly in the same direction as the pin portions, but to a lesser extent.
