Cavity Filling Analysis and Design

For an acceptable molded part to be produced, the polymer melt must completely fill the mold cavity. Accordingly, the wall thickness of the molded part and the gating locations must be specified such that the melt is able to traverse from the gates to the edge of the cavity. Mold filling analysis is used to ensure that the melt can not only fill the mold at achievable molding pressures, but fill the mold as intended to achieve the desired quality.
