Abstract:	The rapid heating cycle has the advantage of improving product quality in injection molding. In this study, steam heating was combined with cool water on the same mold design to achieve dynamic mold surface temperature to establish control. By applying the steam system on a TV housing mold, the advantage of using steam heating for injection molding was then evaluated and compared with water heating by experiment and simulation. The effect of steam on the quality of the part was also studied. Results showed that as steam was used, the heating time of the simple mold plate can be reduced from 18s to 8 s with the heating rate of 9 degrees C/s, and the cooling time is reduced over water heating. When the target temperature is changed from 70 degrees C to 110 degrees C, the heating time of the TV housing mold plate varies from 7 s to 19 s. For the product quality, steam heating showed an improvement in both the gloss and hardness of the TV housing. Crown Copyright (C) 2010 Published by Elsevier Ltd. All rights reserved.
