Abstract
An in-mold vibratile injection compression molding method and molding apparatus thereof are described. While performing a filling stage, a first piezoelectric actuator and a second piezoelectric actuator are use to vibrate the molding material along at least two directions for precisely filling the molding material into the micro-structure in order to avoid the form error, to increase the groove filling rate and to improve the residual stress.
