Abstract

UN NUEVO METODO PARA MOLDEAR UN ARTICULO INCLUYE LA PREPARACION DE UN MOLDE CON UN RESPIRADERO DE DETERMINADO TAMAÑO, DE TAL MODO QUE DEBIDO A LA DIFERENCIA DE VISCOSIDADES LOS GASES QUE HAN DE SER EVACUADOS DEL MOLDE PUEDEN PASAR FACILMENTE A TRAVES DEL RESPIRADERO, MIENTRAS QUE EL MATERIAL QUE HA DE SER MOLDEADO NO PUEDE PASAR RAPIDAMENTE A TRAVES DEL RESPIRADERO. EN EFECTO, EL RESPIRADERO ESTA DISEÑADO DE TAL FORMA QUE EL MATERIAL QUE VA A SER MOLDEADO ENTRA POR EL RESPIRADERO, PERO NO SALE POR EL FINAL DEL RESPIRADERO. EN LA REALIZACION MAS PREFERIDA EL RESPIRADERO TIENE LA FORMA DE UNA RANURA DELGADA SIMILAR A UNA CINTA, DE TAL MODO QUE EL MATERIAL QUE VA A SER MOLDEADO EL CUAL ENTRA POR EL RESPIRADERO FORMA UNA CINTA DELGADA DE MATERIAL EXTRUIDO QUE NO NECESITA SER ELIMINADO ANTES DE QUE UNA CAPA DE ACABADO SEA APLICADA AL ARTICULO MOLDEADO.
