Tendum Coating Lamination Machine An extrusion coating lamination machine is used to apply a thin layer of plastic onto a substrate material. The machine works by melting plastic pellets in an extruder and then extruding the molten plastic through a die, which shapes the plastic into a thin film. The film is then pressed onto the substrate material, which is fed through the machine. Here are the steps involved in the operation of an extrusion coating lamination machine: 1. The plastic pellets are fed into the extruder hopper, which is located at the top of the machine. 2. The pellets are then melted in the extruder, which is a heated cylinder with a screw inside that moves the plastic along the length of the cylinder. 3. The molten plastic is then pushed through a die, which shapes the plastic into a thin film. 4. The substrate material is fed through the machine on a roller. The film is pressed onto the substrate material with the help of a nip roller, which applies pressure to ensure the film adheres to the substrate. 5. The coated substrate material is then cooled using a cooling system, such as a series of water-cooled rollers. 6. The coated substrate material can then be wound up onto a roll for further processing. Overall, an extrusion coating lamination machine works by melting plastic pellets and extruding them through a die to create a thin film, which is then pressed onto a substrate material. The machine can be used for a variety of applications, such as coating paper or cardboard with plastic to make it more durable, or laminating multiple layers of plastic to create a barrier film.
