Workflow of an Extrusion Lamination Machine
Feeding: Raw materials are delivered into the feed throat of the extruder via a conveyor belt or screw conveyor.
Melting: The raw materials are melted into a fluid state under the high-temperature environment inside the extruder.
Mixing: The molten materials are thoroughly blended in the mixing zone to ensure an even distribution of the different components.
Extrusion: The mixed material is extruded through a T-die to form a uniform molten film.
Lamination: The molten film is immediately coated onto a moving substrate, achieving a firm bond through the use of a chill roll and a pressure roll.
Cooling and Setting: The circulating cooling water system rapidly dissipates heat, ensuring the laminated film cools, flattens, and properly sets.
Winding: The finished product is wound into a roll after edge trimming.
