Plastic signs marking the production process

Henan Vientiane logo to share with you as signs marking plastic substrate material signs, is widely used in plastics and developed, with the process for making and production process is different, plastic signs marking materials generally have the following types of : 1. Using two-color injection molding. This method of high production efficiency, saving non-ferrous metal, plastic signs writing on the same plane, easy to use, writing Qing Xi, durable, but is only suitable for simple and slightly larger numbers or symbols. Two injection molding method is: first forming a plastic insert number sign, and then injection molded plastic frame; or the first frame as a plastic injection molded insert, and then injection molding numerals. We should pay attention to the selection of injection molded plastic insert than the melting temperature should Gao injection molding temperature of the plastic in order to prevent the second injection, the original surface of the insert to melt, affect the writing. 2. The polyester film plate. Compared with metallic polyester film, thin polyester film label (0.05? 0.15mm), a variety of special-shaped or complex parts, assemblies application is very convenient, which is the other signs that fall. Low cost, saving colored Golden Mile, easy to use, the better. But should only make a small plate. Characteristics of polyester film produced signs are: using photolithography methods of gravure printing drum stencil paint and chrome, and then paint on the polyester film is printed and dried, and then vacuum aluminum, unpainted portions in bright plated thin aluminum layer was trimmed with adhesive on the article, high temperature, low temperature and humidity test experiment, there was no blistering or adhesion loss is not strong and so on. 3. Direct molded plastic number sign. Matrix material into digital signs or symbols engineering instrumentation, electronic equipment and other parts, components and machine in the cabinet, with other signs of production are more cumbersome, and the use of the plastic molding directly Braille (or concave words) method is more convenient. This process method is engraved on the injection mold base part of the female (or male> characters or symbols can be, using the advantages of Braille is simple engraving, a concave mold processing difficulties, but the writing is not easy to break something. the efficiency of this method is the production numbers and symbols are higher than other methods, but the handwriting Sharpness is not enough, and only applies to the fines products forming a relatively simple writing symbols. The signs require a larger size, you can use plexiglass by machined bonding together. Such signs Qing Xi beautiful, color can diversify, typically three-dimensional, but material costs, costs of working hours, high cost, only for the production of modeling demanding and requires a small number of occasions.
