Abstract
METODO PARA LA ORIENTACION MOLECULAR DE MATERIAL DE PLASTICO. SE INTRODUCE EL MATERIAL DE PLASTICO EN UN RECIPIENTE LLENO CON LIQUIDO CALENTADO Y SE INTRODUCE DICHO LIQUIDO BAJO PRESION EN EL INTERIOR DEL TUBO QUE, DEBIDO A LA PRESION INTERNA QUE PREVALECE EN EL TUBO, SE EXPANDE EN LA DIRECCION TRANSVERSAL DEL TUBO, AL MISMO TIEMPO QUE LA PARTE DEL TUBO SITUADA EN EL RECIPIENTE ES ACONDICIONADA POR CALENTAMIENTO POR MEDIO DEL LIQUIDO CALENTADO. ES UTIL PARA LA FABRICACION DE ENVASES QUE COMPRENDE CONFIGURACION Y CIERRE HERMETICO.
