MOLDING DEVICE AND MOLDING METHOD

摘要

A molding device for molding a resin composition into a sheet shape by pressurizing the resin composition has a pair of rollers arranged parallel to one another. Each of the rollers has a columnar or cylindrical core portion and an outer layer provided on an outer periphery of the core portion. The outer layer is constituted of the ceramic material. A thickness of the outer layer is in the range of 0.2 to 100 nm. Further, an arithmetic mean deviation of a profile Ra of an outer peripheral surface of each of the rollers defined by JIS B 0601 is in the range of 0 to 2 μm.
