Abstract
Die slide injection as eco-friendly manufacturing process in the injection molding greatly reduce the cost and time because they can simplify the conventional process through elimination additional process, as well as has advantage of precision, dimensional stability, and completeness as functional device. However, this process must resolve some defects like whitening, resin infiltration, blowhole, resin overflow, etc. In this study, the process conditions of the injection molding are optimized by using the CAE analysis and Taguchi method. The injection molding analysis is simulated by employing the Moldflow insight 2010 code and the 2nd injection is by adopting the Multi-stage injection code. Moreover, according to two kind of polypropylene and one kind of Polyethylene, results of experiments were compared by measuring as follows; TGA(Thermo Gravimetric), DSC(Differential Scanning Calorimetry), IR(Infrared Ray). In this way, the applicability of the Die slide injection was confirmed.
