Abstract

A method for molding thin parts made of single-component polyurethane plastics consisting in depositing on the lower part (118) of the mold (116), while the mold (116) is at least partially open, the fluid plastic material in the various regions in an amount which is proportional to the width of the impression, and subsequently, closing the mold (116), compressing the fluid material, and allowing the system to cool.
