| Popis: | 100 Plastic parts with micro structure are important components in optical products and electronic consumer products. Such as lighting applications, LCD backlight light modulus diffusion film, prism film, etc. Plastic parts with micro structure Can be designed with the demand on optical performance. Therefore, how to produce high replication parts with micro structure are the objet for this study. There are lots of molding parameters which influence the quality of molded part. In order to satisfy the requirement of high replication, and dimensional stability, the tranditional injection technology needs to be enhanced. In this study, a 1.5〞 light guide panel is illustrated to demonstrate how to improve the quality by CAE analysis and design of experiment method. First, we use CAE software to analyze the molding parameters such as： melt temperature, injection speed, injection pressure, holding pressure, etc. After a feasible combination of molding parameters is determined, the Taguchie method is implemented to validate the predicted molding parameters. For dimension measurement, microscope is used to check the length, width, and depth of the molded part, respectively. The results show that the real warpage of the part is similar to the predicted result calculated by CAE analysis. In addition, the replication of micro structure of the part is independent on the gate location. |
