MANUFACTURING EMBOSSED ARTICLES OF SYNTHETIC RESIN

摘要

An apparatus for manufacturing an embossed article of synthetic resin comprising heating a synthetic resin sheet to a softening temperature; overlaying the heated synthetic resin sheet on an embossing die made by an electro-chemical molding process and having an embossing surface with an embossing pattern thereon and a multitude of fine vacuum pores distributed uniformly over the entire embossing surface; and forcing the synthetic resin sheet against the embossing surface by applying suction through the fine vacuum pores to imprint the embossing pattern onto the synthetic resin sheet.
