Description

1261545 V. INSTRUCTION DESCRIPTION α) — [Technical Field of the Invention] The present invention relates to an automatic screen printing method for 1 positioning and injection molding, which mainly utilizes the principle of screen four-color sleeve, so that the creation is not only printed Fast speed' excellent color performance, and can be used with positioning and injection molding machine. When the injection molding machine performs the shooting operation, the same ink will be transferred to the injection material to become a finished product. The basin is also a combination of structures that offer a variety of color variations. [Prior Art] Currently, IMR printing methods are mainly used for rotary printing.

Four printing methods, such as electric 'and direct injection molding, in which the wheel transfer: the test time of the brush needs to be longer, and the loss is large /, the multi-potential striker Lan η △ / 士士化费 cost is higher, color Poorness, poor performance of metallic color; and time and cost of baking on the two, and not in line with economic benefits; electricity ^ the production of the most commercially available products;;; injection molding is currently required to join the color, but each One: before the molding, in the change of raw materials..., it is impossible to produce a color map for use in a variety of colors, [Summary of the Invention]

The main purpose of the invention is to solve the above-mentioned defects, avoid the defects, and use a low loss, not only the printing speed is fast, the color table township can be used together with the positioning and injection molding machine, and the same is provided. The printing method of the color change of the shirt. Jiang Answers the above-mentioned party, the invention first uses an automatic screen printing machine, / PET material (film), after printing a layer of transparent hardener,

Page 5 1261545 i5, invention description (2) i i then dry processing; then use the automatic screen machine to print the above

I The material of the transparent hardener (film) is printed on the four-color sleeve oil in sequence. After each color is printed, it is dried and then brushed; the above-mentioned film that has been printed and printed by automatic screen printing) Continue to print the last layer on the automatic screen printing machine (and then dry processing, which is the semi-finished product after printing; the semi-finished product (whole roll type), and the positioning and injection molding machine and plastic prototype, while injection molding The embodiment of the present invention will be described as follows: Please refer to "FIG. 1" for the supply of the present invention. Schematic diagram of automatic screen printing method for in-position and injection molding. The automatic boring method for I MR and positioning and injection molding of the present invention is mainly low loss, not only printing speed, color table, but also positioning and The injection molding machine is used, and the printing method for providing changes is provided. In order to achieve the above method, the step program of the present invention includes screen printing. Baking, the second color from the copy requires color printing, the last color printing, baking and injection molding steps; First, the first step is to use automatic screen printing machine, secondary automatic screen printing 1 is Full-volume PET material (film brushed with a layer of transparent hardener (cutting ink) 2, this hardener 2 has a layer of field one, two, enamel, ink, then the next color printing material (thin: > ink printing After the material is injected into the molding material with the pattern IMR and the stencil printing as shown in the figure shows the excellent diversity of colors: the first brush, baking for the first), printed for the purpose of 1261545 I five, invention Description (3) After the injection molding, the ink surface is rendered scratch-resistant (the ink is formulated according to the specified formula), and then the first drying treatment 3 is performed. This first drying treatment 3 is performed by using an oven. °C~1 0 0 °C baking for 2~5 minutes and instant drying; ! After the first step above, the second step of the fourth color automatic screen printing 4 is performed, and then the automatic network is used. Plate machine, the above printing has a layer of transparent hardening (Scratch-resistant ink) 2 material (film) surface printed with ink and hardener 5, and then a second drying process 6, this second drying process 6 is to use oven to 80 ° ~ 1 0 0 ° C baking for 2 to 5 minutes and drying instantaneously; After the second step is completed, the third step is to perform printing on the surface of the material (film) after the second color automatic screen printing 7 is performed by the screen printing machine. And the hardener 8 is further subjected to a third drying treatment 9 , and the third drying treatment 9 is instantaneously dried by baking in the oven at 80 ° C to 1 0 ° C for 2 to 5 minutes; After the three steps are completed, the fourth step is to perform the third color automatic screen printing by using the screen printing machine, and then printing the ink and the hardener 1 1 on the surface of the material (film), and then performing the fourth drying treatment 1 2, the fourth drying treatment 1 2 is to use the oven to bake at 80 ° C ~ 1 0 ° ° C for 2 to 5 minutes and instantaneous drying; After the fourth step is completed, the fifth step is to use Screen printing machine for the fourth color automatic screen printing 1 3, after the material (film) table The surface is printed with ink and hardener 1 4, and then the fifth drying treatment is performed. The fifth drying treatment is performed by using an oven at 80 ° C to 1 0 0 ° C. 1261545 I. (4) Bake for 2 to 5 minutes and dry instantly;

After the fifth step is completed, the sixth step is performed to print the material (film) of the automatic screen printing which has been printed, and continue to print the last layer of the ground ink 1 7 on the automatic screen printing machine 16. The sixth drying treatment 1 8 , the sixth drying treatment 18 is to use the oven to bake at 8 (TC ~ 1000 ° C for 2 to 5 minutes and instantaneous drying; the purpose of the aforementioned base color ink is to increase printing In addition to the chroma of the surface, the adhesion of the ink to the shot material is increased when the shot is emitted; and after the sixth step is completed, the seventh step is performed to form the semi-finished product (full roll type), and the positioning and injection molding. The machine and the plastic material are injection-molded, and the copy ink is transferred to the injection molding material at the same time of injection molding, that is, it becomes a complete finished product. Further, the above-mentioned ink is a hardener, and the hardener is formulated according to the formula in 2~ 8%. Further, the four-color ink set in the above-mentioned sequential printing can be determined according to the color specified by the customer.

As can be seen from the above, the present invention is an automatic screen printing method for I MR and positioning and injection molding, which has a fast printing speed, excellent color expression, and can be used with a positioning and injection molding machine. With the structure of providing a variety of color changes, and it has not been used in public, in accordance with the provisions of the Patent Law, 提出 file a new type of patent application, please grant a patent, it is a virtue.
