Manufacturing process of packaging products by orthogonal test

摘要

For most plastic packaging products, injection molding is the most convenient, simple, widely applicable, especially for those thin, complex structure, smooth surface, and small moulds. Overdependence on experience, it is difficult to quickly design excellent products with short production cycle. In this paper, a common thin CD packaging mould was taken as a research object. By orthogonal experiment method and MPI software obtain the amount of warping deformation and a better group of process parameters. Within the range of orthogonal test, we explore the influence of various process parameters on warpage of injection. Besides, according to variance analysis that it is different from visual analysis to explore the main factors significantly, so that we obtain the most reliable and the best group of process parameters.
