INTEGRATION OF FORMING AND INJECTION MOLDING PROCESSES ON IN-MOLD DECORATION PRODUCT DEVELOPMENT

摘要

Decoration processing for injection molded parts, such as painting, printing, hot stamping, electroplating, and so on, is commonly applied to enhance the surface quality and product value. Due to extra processes, cost, and pollution problems increase. One of great solutions, which is performed in-mold decoration, has been utilized to minimize the processes for years. However, since it is so complicated from film forming to injection molding, how to realize the process mechanism is the crucial factor. In this study, the integration of forming and injection molding processes is proposed and performed both experimentally and numerically.
