Abstract

Un método de hacer funcionar una máquina de moldeo por inyección que tiene un émbolo o empujador que inyecta un material curable dentro de una cavidad de molde y un conjunto de pistón y cilindro de áreas desequilibradas para desplazar el émbolo durante la carrera de inyección del mismo, que comprende: desplazar el émbolo durante un intervalo a una primera velocidad suministrando fluido a presión al conjunto de pistón y cilindro desequilibrado en un modo de funcionamiento regenerativo , y desplazar el émbolo durante un intervalo diferente y a una velocidad diferente menor suministrando fluido a presión al conjunto de pistón y cilindro desequilibrado en un modo de funcionamiento no regenerativo
