寸法に切断する。In general, automotive moldings, such as door weather strip moldings, are generally made of stainless steel sheets or galvanized steel sheets with a U-shaped cross section, as shown in Figure 1.
It consists of a mounting part N made of a thermoplastic synthetic resin P such as PVC (polyvinyl chloride resin) that covers the mounting part N, and upper and lower lips L protruding from the back side of the mounting part N. The supplement part N is attached to the opening edge of the door panel, and the lip part slides against the surface of the window glass that moves up and down to drain water and remove dust. Such a molding M is manufactured by the method shown in FIG. In FIG. 2, the coil-wound steel plate Z of the stand 1 passes through an adhesive applicator 2, at which time adhesive is applied to its surface side, and then induction baking is performed by heating the stand 1 as described above. The applied adhesive adheres to the steel plate Z, and this steel plate is temporarily cooled in a cooling water tank 4 and then supplied to a roll forming machine 5, where it is formed into a substantially U-shaped cross-sectional shape as shown in FIG. , is supplied to a high frequency preheater 6, where it is preheated, and without extruding the synthetic resin P, is supplied to an extrusion mold having an extruder 7, where it is extruded together with the synthetic resin P to form the cross section shown in FIG. molded into a shape. Next, molding M
In order to give gloss over a predetermined width W on the surface side, the synthetic resin is irradiated with heat by an infrared lamp 9 within the range of the predetermined width W to melt the surface side of the synthetic resin, and is cooled in a secondary cooling water tank 10. It is led to cutting fi12 via take-off fill and cut into a predetermined size.

部分Ｙの両端の境界Ｔにぼけが生じてしまい、より鮮明
な境界がめられるときには十分でないという欠点を有し
ていた。As shown in FIG. 1, the heat irradiation step is carried out by covering the area other than the area to be glossed with a mask F and irradiating the area exposed from the mask F with light from a lamp unit 9. In addition, the above mask F is molding M
In order to avoid damaging the molding M during the movement process, the molding M is spaced apart and placed in a non-contact state. However, according to the conventional molding manufacturing method, the light from the lamp fi9 passes through the mask F.
As a result, the boundary T at both ends of the area Y to which gloss is to be applied becomes blurred, which is disadvantageous in that it is not sufficient when a clearer boundary is desired.

という欠点を有していた。Further, according to the conventional molding manufacturing method, a lamp machine 9 is required, and it is difficult to maintain a constant heat irradiation distribution over the width W, making it difficult to adjust the heating uniformly on the surface side of the molding. (It had the disadvantage that it was difficult to obtain uniform gloss.

The core material is heated by induction, and based on this heat, the synthetic resin with a low melting temperature is melted to give gloss to the surface, thereby eliminating the above drawbacks, and will be explained in detail below using examples. do.

この場合、モールディングＭにおいて、＠Ｗに渡って光
沢を与えるべき部分ＹＭの合成樹脂Ｐ１は他の部分の合
成樹脂Ｐよりも熱溶融温度が低いものから成形される。In this case, in the molding M, the synthetic resin P1 of the portion YM that is to be glossed over @W is molded from a material having a lower thermal melting temperature than the synthetic resin P of the other portions.
このような性質の異なる合成樹脂を一体化するには合成

た二色押出成形法が用いられる。In order to integrate such synthetic resins having different properties, a two-color extrusion molding method is used in which an extruder Ia8 for extruding the synthetic resin P1 is provided and extruded.

される。The synthetic resin M includes a magnetic material such as the steel plate 2 as a core material, and the synthetic resin P1 is integrated on the surface side of the steel plate Z. Reference numeral 11 denotes an induction heating coil extending from the induction heating device, and after the molding M extruded from the extrusion mold passes through the hollow part (3) of the induction heating coil, it is cooled in a cooling water tank 10.

Since the synthetic resin P1 is formed over the width W, it is possible to provide gloss over the width W. In this case, since the synthetic resin P has a higher heating melting temperature than the synthetic resin PI, it does not melt much and does not impart gloss to the surface, thereby increasing the contrast in gloss between the two. Therefore, it is possible to provide a clear separation at both ends of the YA to which gloss is to be applied, and it is possible to eliminate the blurring that occurs at the conventional boundaries. Also, the conventional lamp l149. Since the mask F and the like are not required, the equipment is simple, and the synthetic resin P1 can be heated uniformly across the width, resulting in uniform gloss.
