Abstract

La presente invención se refiere a un ensamble de molde para producir una unidad integral de preforma de lente-copa de molde, adecuada para acabado subsecuente a una lente-óptica, que comprende: una copa molde que tiene una cavidad definida en él para recibir monómeros de material de lente, sin curar, y una superficie soportadora de matriz, sobrepuesta a, y que circunscribe dicha cavidad, adaptada para recibir sobre ella una matriz para coactuación con ella, para contener los monómeros dentro de la cavidad cubierta, mientras se curan dichos monómeros, y una matriz radial, situable sobre la superficie soportadora de matriz, mientras se curan los monómeros hasta acoplamiento adherente con la copa de molde, y removible de allí para proveer una unidad integral de preforma de lente-copa de molde.
