The invention relates to a device and a method for filling a molded article that comprises a plurality of at least partially communicating interior cavities with a liquid phase or for removing the excess of a liquid phase used to coat a molded article comprising interior cavities. The inventive method is characterized in that filling or removal of the excess from the interior cavities is carried out by way of an acceleration process and a subsequent braking process, deceleration being faster than the previous acceleration, with the proviso that the inertial forces caused by deceleration and acting upon the excess liquid phase are higher than the sum of the other opposite forces also acting upon the liquid phase.
