Abstract
"MéTODO DE MOLDAGEM PARA A FABRICAçãO DE LENTESTERMOPLáSTICAS FINAS". São mostrados novos métodos demoldagem para a fabricação de lentes termoplásticas finas e, emparticular, lentes oftalmológicas finas, que têm uma espessura decerca de 1 mm ou menos no ponto mais fino das mesmas. Osmétodos de moldagem mostrados provêem lentes as quaiscarecem de quaisquer artefatos de abrasão ou de polimento nasuperficie e, também, carecem de quaisquer marcas deacabamento negativas abaixo da superfície nominal.
