Here we see the extrusion blow molding process used to manufacture plastic pallets. In this method, a molten plastic tube, called a parison, is extruded downward and inflated with compressed air inside a heavy-duty mold. As the mold closes, the plastic expands to take the shape of the pallet. Cooling systems quickly solidify the material, producing a durable, lightweight, and reusable plastic pallet. Blow molded pallets are highly valued for their strength, resistance to moisture, and long servi
