INVESTIGATION ON VARIOUS VARIOTHERM PROCESSES IN INJECTION MOLDING

摘要

In recent years, to eliminate defects and improve the product quality, many variotherm processes have been proposed and commercialized in injection molding. However, what the true function is for each technology and how the efficiency is from one technology to the other, are still not clear. In this study, we have systematically conducted various technologies, including Conventional Injection Molding (CIM), Rapid Heat Cycle Molding (RHCM), Induction Heating Molding (IHM), and Electricity Heating Mold (E-mold) by using 3D Transient Cool technology. The functions and the heating-cooling efficiency for each technology can be visualized. The comparison for all technologies is also performed.
