Abstract

UN METODO Y APARATO PARA INYECCION DE POLIMEROS TERMOPLASTICOS DE MOLDEO, EN DONDE UNA CAPA DE GAS PRESURIZADO SE PROPORCIONA ENTRE AL MENOS PARTES (11) MOLDEADAS ELEGIDAS Y EL POLIMERO (28) ENFRIADO. EL GAS COMIENZA LA CONTRACCION MIENTRAS EL POLIMERO SE ENFRIA Y PERMITE QUE SEAN SUSTANCIALMENTE ELIMINADAS MARCAS VISUALES DE CAVIDADES. ADEMAS, SE REDUCEN LOS TIEMPOS DE CICLO, PERMITIENDO QUE SEA RAPIDAMENTE ENFRIADO POR EMPUJE DEL POLIMERO (28) CONTRA EL MOLDE (27) EXTERNO Y ENFRIANDO EL OTRO MOLDE (27).
