Thermoformed pallet

Thermoforming takes place when a thick plastic sheet is clamped onto a frame and heated, then this softened, pliable sheet is forced by either pressure or vacuum to adapt to the shape of a pallet tool.
Once the sheet has formed to the configuration of the tool and it has cooled down, it is removed from the frame. The outer perimeter of the pallet is trimmed off to yield the finished part.
Twin-sheet thermoforming is a variation of this process whereby two separate sheets of plastic are heated in two separate sets of tooling and then fused together under pressure to yield a pallet with a hollow section or sections.
