Fabrication apparatus and manufacturing method of plastic film

A fabrication apparatus of plastic film including an extrusion element, a gear pump, a cooling roller, a winding roller, and a detector group is provided. The extrusion element has an inlet and an outlet, and the plastic film is extruded from the outlet. The gear pump is disposed adjacent to the inlet and is configured to control throughput of the extrusion element. The cooling roller is disposed adjacent to the outlet, and an air gap distance is remained between the cooling roller and the outlet. The cooling roller is configured to control the extruding speed of the extrusion element and define a conveying direction. The winding roller is disposed behind the cooling roller in the conveying direction and collects the cooled plastic film. The detector group is disposed between the cooling roller and the winding roller, and the detector group includes thickness detector and width detector. A manufacturing method is also provided.
