Abstract

CRISTALIZABLE PRINCIPALMENTE AMORFO EL MATERIAL TERMOPLASTICO ES CRISTALIZADO A UNA TEMPERATURA SUPERIOR A LA TEMPERATURA DE TRANSICION DEL CRISTAL DEL MATERIAL (13) POR SOMETER EL MATERIAL A LA ELEVADA TEMPERATURA PARA COMPRIMIR FUERZAS. POR MEDIO DE ESOS EL ESPESOR DEL MATERIAL COMO UNA REGLA ES REDUCIDO POR LO MENOS 20%, PREFERIBLEMENTE POR LO MENOS 40%. EN UN DISPOSITIVO PARA LA APLICACION DEL PROCEDIMIENTO UN EMBOLO (20) Y UN MOLDE (30) SON MOVIDOS A UNA DISTANCIA MINIMA A LA CUAL EL ATERIAL TERMOPLASTICO (13) COLOCADO ENTRE EL EMBOLO LA PARTE DEL MOLDE ES SOMETIDO A FUERZAS COMPRESORAS. EL EMBOLO Y LA PARTE DEL MOLDE ESTAN PROVISTOS CON LOS ELEMENTOS (29,39) PARA LA COLOCACION Y MANTENIMIENTO DE UNA TEMPERATURA ESPECIFICADA EN AVANCE DE LAS SUPERFICIES (23,33) CON LA CUAL EL EMBOLO Y LA PARTE DEL MOLDE RESPECTIVAMENTE HUNDAN CONTRA EL MATERIAL TERMOPLASTICO.
