<p>The production of injection-molding parts, comprises punching parts from a band, injecting these parts in an another processing step with plastic, passing through the band in horizontal position by a punching device (3a) and an injection molding device (4a, 4b), subjecting the band alternatively in a first groups of processing cycles to a first number of punching process and after carrying out a feed motion for each processing cycles, and subjecting the band in a second groups of processing cycles to a second number of injection molding process. The production of injection-molding parts, comprises punching parts from a band, injecting these parts in an another processing step with plastic, passing through the band in horizontal position by a punching device (3a) and an injection molding device (4a, 4b), subjecting the band alternatively in a first groups of processing cycles to a first number of punching process and after carrying out a feed motion for each processing cycles, and subjecting the band in a second groups of processing cycles to a second number of injection molding process. The first number is larger than the second number. A component punched in several processing cycles is subjected partially simultaneously to the injection molding process. A single injection molding process is carried out between two sequential groups on each other by punching process. The total duration of the first group of processing cycles are carried out in the punching process and the total duration of the second group of processing cycles are carried out in the injection molding process. A feed rate of the band is released over a control unit (5) between each processing cycles of the first groups and the feed rate is interrupted for a processing cycle of the second groups. The punching process and the injection molding process are carried out immediately one after the other. An independent claim is included for a device for the production of injection-molding part.</p> |
