1. Screen printing of electronic parts of electronic products Electronic products, especially radio products such as radios, tape recorders, television sets, etc., have high requirements for appearance. Art designers pay great attention to the appearance decoration of the products, and the current process for exterior decoration in China is less, which limits the ideas of the artists, so that they can only use the size of the products, the use of various lines, and the plastic itself is limited. The color to change the look of the product. After the development of plastic screen printing, it has brought convenience to the decoration of electronic products. Therefore, in recent years, plastic silk screen printing of various electronic products in China has been widely used.

2. Screen Printing of Plastic Signage In recent years, decorative parts for silk-screened graphic characters after plastic signage and plastic molding have developed rapidly. For example, screen printing on PVC plastic sheet (PVC board), polycarbonate, ABS, plexiglass, modified polystyrene plastic parts, has been widely used, and achieved good decorative effect and economy. benefit.

3. Screen printing of soft and hard plastic parts 1 Screen printing of plastic hoses. There are several methods for printing plastic hoses, the main method of which is thermal transfer. The thermal transfer method uses a sublimation dye ink or other material to print the graphic onto the transfer paper first, then attaches it to the substrate, and heats it from the back side of the transfer paper to sublimate the paper dye. The image is transferred onto the substrate. After the plastic hose is subjected to surface treatment, it is passed between the hose and the heated iron plate by the sun gas, and the transfer paper is pushed to the hose by heating the iron plate, and the transfer is completed by heating. After the transfer, the hose enters the drying device, and the drying temperature is generally about 65 °C. 2 silk screen of soft plastic. Soft plastics are often used to make toys, such as inflatable cartoon toys. It is usually made by silk-screening on a soft sheet-like plastic, then cutting and hot-synthesizing. The thickness of the material used is generally 0.8 to 3.0 mm. When two-color screen printing is performed, most of the plastics will expand and contract, and the color error of the second color and the first color will appear. This color misregistration causes the product to lose its original value and cannot be placed on the shelf as a good product. For this reason, multi-color printing can only be carried out with a long-length printing press capable of fixing soft plastics. When printing on long screens, the substrate should be fixed with an adhesive. It is worth noting that toy printing must use non-toxic, harmless inks as specified in the relevant standards. 3 silk screen of hard plastic products. Hard plastic products are available in both hard and molded products. Tickets, signboards, instrument dials, cosmetic containers, etc. are all made of hard plastic.

4. Screen printing of the instrument panel The surface material of the panel may be metal, various plastics and paints. The appropriate ink is used to screen some text and graphics on the panel, indicating some functions of the instrument and equipment, and also beautifying the panel. Screen printing text and graphics require clear, good adhesion and wear resistance, and also requires soft and elegant color to give people a feeling of beauty. Here we mainly discuss how to improve the quality of the panel with the silk screen process.

5. Screen printing of color polyester signs Polyester signs are a new type of signage that has been rapidly developed in China in recent years. Because of its bright color, good decoration, convenient paste, simple manufacturing method and low cost, it has been well received by users and quickly obtained in high, medium and low grade electronic products, household appliances and stationery. Universal application. At present, there are many specialized factories in China that produce such signs. However, since the production processes of these factories are designed according to the needs of large-scale label processing, for those polyester products with many varieties and small quantities, no matter from the processing technology or production cost, adapt. Here is a process technology for printing color polyester labels by screen printing, which is used for the production of small-volume, multi-varietal color polyester signs.
