Abstract

PROCEDIMIENTO PARA LA FABRICACION DE PIEZAS MOLDEADAS A BASE DE MATERIAL SINTETICO TERMOPLASTICO. A PARTIR DEL MATERIAL SINTETICO PLASTIFICADO SE FORMA UN SEMIPRODUCTO POR EXTRUSION CONTINUA Y PROGRESIVA DE UNA BANDA DE MATERIAL. SE ESTABILIZA EL SEMIPRODUCTO MEDIANTE ENFRIAMIENTO Y SE EFECTUA UN PRIMER TERMOACONDICIONAMIENTO, QUE AJUSTA EL ESTADO DE CRISTALINIDAD DEL SEMIPRODUCTO. SE FORMAN PIEZAS MOLDEADAS ESTABLES A PARTIR DE SEMIPRODUCTO REALIZANDO UN SEGUNDO TERMOACONDICIONAMIENTO.
