Abstract

Patente de Invenção: <B>"PROCESSO DE MOLDAGEM DIFERENCIADA EM PRENSA"<D>. Um processo para a conformação descontínua de plástico por meio de deslocamento de volume em uma cavidade, em cujo processo a introdução de energia de conformação tem lugar através de no mínimo duas partes movidas da superfície da cavidade, no mínimo uma metade de molde contendo uma ou mais peças movidas em relação a ela, no mínimo uma parte da energia de conformação sendo introduzida através do movimento relativo destas partes, e somente parte da superfície da cavidade estando envolvida na introdução da energia de conformação, bem como um dispositivo para realizar o processo e componentes produzidos por meio do processo ou no dispositivo.
