Abstract

La presente invención se refiere a un proceso para preparar un producto de plástico recubierto que comprende un substrato de plástico que lleva ligado o unido a por lo menos una porción de su superficie un material de recubrimiento protector, incluyendo dicho proceso las etapas de proveer un molde que incluye por lo menos dos secciones de molde que cooperan entre sí, el cual tiene una cavidad e su interior para formar el substrato de plástico y en el cual por lo menos una porción de la cavidad define una superficie de cavidad de molde adyacente a la cual va a ser moldeada una superficie terminada del producto plástico, caracterizándose dicho proceso por: A) disponer o colocar el material de recubrimiento protector a traves de la superficie de la cavidad de molde; B) cerrar el molde; y C)inyectar los materiales precursores polimericos en el interior de la cavidad, detrás del material de recubrimiento protector, por virtud de lo cual los materiales precursores polimericos llenan la cavidad de molde, deforman simultáneamente el material de recubrimiento protector para conformarlo sustancialmente a la superficie de la cavidad de molde y reaccionan in situ para formar el substrato de plástico y para unirse o ligarse químicamente, en forma simultánea, al material de recubrimiento protector.
