Abstract

La presente invencion se refiere a un metodo para fabricar un panel, que utiliza una primera mitad (12) del molde que tiene un reborde (24) que se extiende perifericamente y una segunda mitad (14) del molde. La primera mitad (12) del molde se mueve con relacion a la segunda mitad (14) del molde para definir una primera cavidad del molde con el reborde que se extiende dentro de la primera cavidad del molde. Un primer material (20) fundido se inyecta en la primera cavidad del molde y se deja solidificar para formar asi una muesca (26) dentro del primer material (20) solidificado que corresponde a la forma del reborde (24). Se forma una segunda cavidad del molde la cual tiene una trayectoria de flujo entre el primer material (20) solidificado y la primera mitad (12) del molde, que comprende una serie de virajes en la vertical que presentan una barrera para el flujo de material. Un segundo material (30) se inyecta en la segunda cavidad del molde y se deja curar sobre el primer material solidificado.
