摘要

In the micro-featured injection molding process, mold temperature would directly affect the shrinkage, warpage and residual stress. Although high mold temperature could assist melt-flow within micro-featured cavity, reduce molding pressure and improve the replication accuracy, the long cycle time also leads to high production cost. Therefore, rapid mold temperature control to achieve micro molding quality without significant increase in cycle time is one of the important concerns. In this paper, the principle and usage of electromagnetic induction to achieve the rapid mold surface temperature control including system establishment is introduced. Its successful applications to molding light guide plate with micro-feature design on both sides and high aspect ratio micro molding are also illustrated.
