Abstract

PROCESO DE FABRICACION POR MOLDEADO DE UNA PIEZA QUE COMPRENDE UNA CAVIDAD (5) INTERNA QUE SE PRESENTA EN FORMA DE UN ELEMENTO DE INSERCION (3) REALIZADO EN UN PRIMER MATERIAL (2) TERMOPLASTICO, RECUBIERTO AL MENOS PARCIALMENTE POR UNA CAPA DE UN SEGUNDO MATERIAL (6) TERMOPLASTICO DE RECUBRIMIENTO. SEGUN LA INVENCION, SE PREVE UNA CONTRAPRESION EN LA CAVIDAD INTERNA (5) CUANDO EL ELEMENTO DE INSERCION TODAVIA ES MALEABLE DURANTE LA FASE DE COLOCACION DEL MATERIAL DE RECUBRIMIENTO (6). LA INVENCION SE REFIERE IGUALMENTE A UNA APLICACION DE ESTE PROCESO A LA FABRICACION DE PIEZAS TALES COMO PARTICULARMENTE EMPUÑADURA DE PUERTAS DE VEHICULOS.
