Abstract

Esta invencion se relaciona con un proceso de moldeo por inyeccion para suelas en compuestos a base de "EVA" expansibles y de reticulacion, caracterizado porque durante la etapa de enfriamiento de la suela moldeada, la contraccion espontánea de la misma es detenida por medio de una plantilla que consiste de una placa conformada, rígida colocada sobre la placa de tal manera que su borde se une con un borde de perímetro realizando específicamente sobre la superficie superior de la placa, cuyas dimensiones ya no se reducen ni durante la fase de enfriamiento restante o después del enfriamiento.
