| dc.description.abstract | Optical plastic lenses are widely used in various electronic products, whose strength and light weight enabling to make mass production in mold injection molding. In the molding process, molds have played an important role. As higher precision is required, optical lenses are increasingly difficult in getting their substantial improvement in the manufacturing and molding processes. Moreover, there are no fixed design patterns. This study is to use the entity optical plastic lenses to illustrate the differences in design between optical components and general products. In addition, make plans on mold design process. By conforming to the design process and design precaution, have designs of templates and mold cores. Next, in application of traditional and non-traditional machining equipment, templates and mold cores are treated through segmented processing, which can improve the precision of molds. Finally, by changing the gate type, Taguchi experimental methods of the injection molding have been used to seek the optimum molding conditions and the gate types, providing standard designs and manufacturing processes. | en_US |
