The process of sheet extrusion involves several key steps:
Material Feeding: Raw plastic material, typically in the form of pellets, granules, or flakes, is loaded into a hopper. Additives like colorants and UV inhibitors can be mixed in at this stage.
Melting and Mixing: The material is gravity-fed from the hopper into the extruder's barrel. A rotating screw inside the barrel melts the plastic through a combination of heat from external heaters and friction. The screw also mixes the material to ensure a uniform and homogeneous melt.
Extrusion: The molten plastic is pushed by the screw through a screen pack and a breaker plate to remove impurities and stabilize the flow. It then enters a flat die, which shapes the molten polymer into a continuous, flat sheet.
Cooling and Calendering: The hot sheet exits the die and is immediately fed into a series of cooling rollers, also known as a calendering system. These rollers cool the sheet, solidify it, and precisely control its final thickness and surface quality.
Trimming and Finishing: The edges of the sheet are trimmed to the desired width. The finished sheet is then either cut into specific lengths or wound onto a roll for storage and transport.
