Abstract

SE FORMA UN MOLDE DE RESINA INTRODUCIENDO RESINA TERMOPLASTICA SINTETICA FUNDIDA (19) EN LA CAVIDAD DE UN MOLDE (13), SUFICIENTE PARA LLENAR COMPLETAMENTE LA CAVIDAD DEL MOLDE. A CONTINUACION, DURANTE EL ENFRIAMIENTO DE LA RESINA, SE INTRODUCE GAS PRESURIZADO EN LA RESINA DENTRO DE LA CAVIDAD DEL MOLDE. EL MOLDE DE RESINA ENFRIA Y SE ENDURECE EN LA CAVIDAD DEL MOLDE MIENTRAS SE MANTIENE EL GAS BAJO PRESION. LA CAVIDAD DEL MOLDE SE DISEÑA PARA FABRICAR MOLDES CON SECCIONES (3) DE CIERRE TUPIDO DESIGUALMENTE DISTRIBUIDO, CONECTADOS A UNA PUERTA (4; 44) POR LO MENOS PARA LA INTRODUCCION DEL GAS A PRESION, QUE FLUYE SOLO DENTRO DE LA RESINA FORMANDO LAS SECCIONES DE CIERRE TUPIDO Y AREAS INMEDIATAMENTE ADYACENTES DEL MOLDE, ABSORBIENDO ASI LA CONTRACCION DE LA RESINA.
