Extrusion coater.

The extrusion Coater extrudes molten plastic into a film through a screw, which is then laminated with the substrate via a pressure roller to form a coating. It is used for waterproofing and barrier treatment of paper and films, commonly found in food packaging and industrial material production.
Selection
When selecting, consider matching the substrate width to the coating width, determine the screw diameter based on the required coating thickness, choose the motor power according to the production speed, and select corrosion-resistant material barrels in combination with the characteristics of the material.
