STAMPER FOR MOLDING PROCESSING OF PLASTIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a stamper suitable for an infrared irradiation type plastic molding processing method. SOLUTION: At least the portion of the main body 3 other than the shaping surface of a stamper 1 having a shaping surface is formed from an infrared pervious material. Infrared rays pass through the main body comprising the infrared pervious material to reach a base material to bring about the temperature rise and melting of the base material in the vicinity of the shaping surface of the stamper by the absorption of infrared energy.
