THE APPARATUS TO DRAW THE PRESSURE DEPENDENT VISCOSITY COEFFICIENT USED INJECTION MOLDING AND THE CONTROL METHOD OF THE SAME

摘要

The present invention relates to an apparatus to draw a pressure dependent viscosity (PDV) coefficient which is a viscosity coefficient for injection molding analysis by using a spiral mold. After proceeding actual injection by using a flow spiral test (FST) mold, the present invention compares and verifies flowing length and inner pressure of the mold with a computer aided engineering (CAE) result, and experimentally draws the PDV coefficient from the comparison result. Through a trial and error method by using FST, the present invention can autonomously derive the PDV coefficient and thus can contribute to the construction of a resin database.
