ABSTRACT:
A window with integral molded stile or frame has been disclosed along with a method for making it. The system according to the invention makes it possible to mold by injection two plastic parts in molding cavities (1', 2'). Material is first injected into the cavity (2') while a core (9) delimits a hole (15) in the molded part. Then the core (9) is removed from the hole (15) and the cavity (1') is placed facing the hole. Material is injected into this cavity. The material passes into the hole (15) and fills an enclosure (14) which molds an assembly stud for the parts molded in the cavities (1', 2').
The invention is applicable to making a window-stile unit for automobiles.
