Verfahren zur Herstellung von Fensterrahmen und Fensterpaneelen mit Fensterrahmen

摘要

A method of making by extrusion-molding an elongated window frame used for a window panel of a vehicle is to use an extrusion molding die (A) which includes a slide core (7,8) defining the cross-sectional shape of the window frame (11), and to move the slide core (7,8) in the extrusion-molding die (A) so that the cross-sectional shape of the window frame (11) is continuously changed along the direction of the length.
