Abstract
EL PROCESO DE FABRICACION DE CUERPOS ELASTICOS, ESPECIALMENTE PELOTAS Y OBJETOS SIMILARES, CONSISTE EN LA INTRODUCCION DE UNA DOSIS APROPIADA DE PLASTISOL DE VINILO (7) DENTRO DE UN MOLDE (2) FORMADO POR DOS CONCAVIDADES UNIDAS (2A,2B); SE SOMETE A DICHO MOLDE (2) A UNA PRIMERA ETAPA DE MOLDEO GIRATORIO BIAXIAL DENTRO DE UNA CAMARA CALENTADA (9) SOMETIDA A UNA TEMPERATURA CAPAZ DE EFECTUAR LA SOLIDIFICACION DEL MATERIAL INDRODUCIDO ALLI, DISTRIBUIDO SOBRE LA SUPERFICIE INTERNA DEL MOLDE (2), AL OBJETO DE FORMAR UNA CAPA EXTERNA (10) DE DICHO CUERPO CONCAVO; SE ACTIVA UNA PRIMERA ETAPA DE ENFRIADO DE DICHO MOLDE (2); SE INTRODUCE UNA DOSIS APROPIADA DE OTRO PLASSTISOL DE VINILO (13) DENTRO DE DICHO MOLDE (2); SE SOMETE DICHO MOLDE (2) A UNA SEGUNDA ETAPA DE MOLDEADO GIRATORIO BIAXIAL AL OBJETO DE FORMAR UNA CAPA INTERNA (17) DE DICHO CUERPO CONCAVO, DENTRO DE UNA CAMARA CALENTADA (16) SOMETIDA A UNA TEMPERATURA APROPIADA PARA VULCANIZAR EL MATERIAL INTRODUCIDO DENTRO DEL MOLDE (2); SE ACTIVAUNA ETAPA FINAL DE MOLDEADO EN FRIO.
