Abstract
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 which includes a slide core defining the cross-sectional shape of the window frame, and to move the slide core in the extrusion-molding die so that the cross-sectional shape of the window frame is continuously changed along the direction of the length.
Claims26
A method of making by extrusion-molding an elongated window frame used for a window panel, using an extrusion-molding die wherein the die includes at least one slide core located therein for defining the cross-sectional shape of the window frame, and extruding resin from the die while moving the slide core in the extrusion-molding die so that the cross-sectional shape of the window frame is continuously changed, wherein a surface which contacts the resin of said at least one slide core has a dimension in a direction in which the resin passes which corresponds to a dimension of a surface of a shaping space of the die which contacts the resin in the direction in which the resin passes.
A method of making a window panel with a window frame wherein a shaped product of resin is formed by extruding through a die resin onto at least a surface of a window panel along the peripheral portion of the window panel, and the shaped product is cured to thereby connect the window panel with the cured shaped product in one piece, wherein a thermoplastic resin is used as the resin;
- the thermoplastic resin is extruded in a softened state by heating it from the die so that the shaped product is formed on the peripheral portion of the window panel;
- and the thermoplastic resin is cured, wherein the die has a cross-section for extrusion which is substantially the same as the cross-section of the window frame.
A method of making a window panel with a window frame wherein a shaped product of resin is formed by extruding through a die resin on at least a surface of a window panel along the peripheral portion of the window panel, wherein the die is provided with at least one slide core inside it, and the slide core is moved during the extrusion of the resin to change in shape a portion of the die through which the resin is extruded, whereby the cross-sectional shape of the shaped product formed on the peripheral portion of the window panel is continuously changed, and wherein a surface which contacts the resin of said at least one slide core has a dimension in a direction in which the resin passes which corresponds to a dimension of a shaping space of a surface of the die which contacts the resin in the direction in which the resin passes.
A method of making by extrusion-molding an elongated window frame used for a window panel, wherein the method comprises the steps of:
- providing an extrusion-molding die wherein the die includes at least two slide cores located therein;
- defining a shaping space, with the slide cores and a main body of the die, which has a cross-sectional shape which is substantially the same as the cross-sectional shape of the window frame;
- and
- extruding resin from the die while moving at least one of the slide cores in the extrusion-molding die so that the cross-sectional shape of the window frame is continuously changed.
A method of making a window panel with a window frame wherein a shaped product of resin is formed by extruding through a die resin on at least a surface of a window panel along a peripheral portion of the window panel, wherein the die is provided with at least two slide cores inside it, and the slide cores, a main body of the die, and the peripheral portion of the window panel define a shaping space which has a cross-sectional shape which is substantially the same as the cross-sectional shape of the window frame, and at least one of the slide cores is moved during the extrusion of the resin to change in shape a portion of the die through which the resin is extruded, whereby a cross-sectional shape of the shaped product formed on the peripheral portion of the window panel is continuously changed.
