Inventor Tan Zhehao Application (patent ) No. 200410056176.5 Application date 2004.08.17 Certification date Approval notice No. 1736689 Approval announcement date 2006.02.22 Manual CD No. D0608-1 Main classification number B29C51/10 (2006.01) I Class number B29C51/10 (2006.01) I; B44C1/00 (2006.01) I. Division of the original application No. of priority items Abstract This invention provides a method for manufacturing a plastic packaging box after first decorating a color printing image, forming screen printing or gravure printing on the front or back of a flat plastic sheet. Letters or characters are printed by means of letterpress printing or transfer printing, and the aforementioned plastic sheet with a pattern or letter is molded by a user according to a user's request using a suction molding machine. The unnecessary corners are cut off, and the bottom surface of the suction molding is molded. The front shell is glued into a plastic box with color printing patterns and text. According to the invention, after the plastic plate is first printed with patterns and characters, the plastic package box with various shapes is vacuum-sucked, and the pattern and characters are clear and the quality is stable. Sovereign item 1, a plastic packaging box first decorated color printing graphics after the molding method is characterized by: 1, plastic mold production: the plastic packaging box is divided into the bottom, front, using polyurethane glue mixed aluminum powder system Corresponding plastic molds or plastic molds made of plaster; 2. Film production: plastic sheets printed with square lattice black lines are molded on plastic molds, deformed in advance according to the deformation of the lattice. , The processed pattern will be output through the art production film; 3, drying net: According to the size of the screen size selection program, drying net; 4, screen printing: drawing requirements to adjust the corresponding high-temperature screen printing oil, the pattern printed on the plastic sheet On; 5, plastic molding: the bottom, the front of the plastic mold are fixed on the plastic machine, fixed printed plastic sheet, adjust the degree of vacuum is maintained at 0.04 ~ 0.08 MPa, temperature 200 °C ~ 300 °C , Time 2 to 60 seconds, in a uniform degree of vacuum and temperature, the bottom surface, the front of the plastic molding respectively; 6, the assembly of finished products: cut the bottom, the front part of the excess after the plastic, the plastic molding of the bottom, front shell body Glued into plastic boxes in various shapes.
