20090302490 | INJECTION MOLDING SYSTEM AND INJECTION MOLDING METHOD - An injection molding system includes an injection mold set to form injection molded products through repeated injection molding, and a printing device to press a film coated with colors onto an intermediate injection molded product to print the colors onto the intermediate injection molded product. The intermediate injection molded product is printed with the colors coated onto the film to shorten a printing time and semipermanently conserve a printed figure. Further, even if the film is deviated slightly from a predetermined correct position, printing a desired figure correctly on the intermediate injection molded product is possible. | 12-10-2009 |
