METHOD FOR MANUFACTURING RESIN PLATE HAVING EXCELLENT PLATE THICKNESS ACCURACY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a wide resin plate capable of realizing an excellent accuracy of a plate thickness by a simple method. SOLUTION: The method for manufacturing the resin plate comprises the step of partly cooling a central part 17a of a sheet 17 of a thermoplastic resin composition to be extruded from a sheet die and cooled in contact with a roll in a width direction (x) on a surface of the side not contacted with the roll of the sheet.
