Abstract
SE PROPORCIONA UN METODO DE AJUSTE DE UN HUECO DE UN CANAL DE CORRIENTE DE PLASTICO (3, 23) EN UN DISPOSITIVO DE FORMACION DE PLASTICOS (1) QUE TIENE UNA PARTE DE CUERPO PRIMERA (7) ADYACENTE A UN LATERAL DEL CANAL Y AJUSTABLE EN RELACION AL MISMO, Y UNA PARTE DE CUERPO SEGUNDA (2) SOBRE LA QUE SE MONTA LA PARTE DE CUERPO PRIMERA MEDIANTE UN AJUSTE PRIETO ENTRE LAS PARTES DEL CUERPO PRIMERA Y SEGUNDA. EL METODO COMPRENDE EL SOMETIMIENTO DE UNA DE LAS PARTES DEL CUERPO A UN CAMBIO DE TEMPERATURA PRIMERO QUE PRODUCE UN DIFERENCIAL DE TEMPERATURA TEMPORAL Y UNA PERDIDA DEL AJUSTE ENTRE LAS PARTES DEL CUERPO, AJUSTANDOSE LA POSICION DE LA PARTE DEL CUERPO PRIMERA SOBRE LA PARTE DEL CUERPO SEGUNDA MIENTRAS SE PIERDE EL AJUSTE, Y, DESPUES, SE SOMETE A LA PARTE DE CUERPO PRIMERA A UN CAMBIO DE TEMPERATURA SEGUNDO CONTRARIO AL CAMBIO DE TEMPERATURA PRIMERO PARA COMPENSAR EL DIFERENCIAL DE TEMPERATURA Y RESTABLECER EL AJUSTE PRIETO ENTRE LAS PARTES DEL CUERPO.
