Abstract
The problem of wet-cast concrete products getting stuck in a flexible mold during demolding is solved, prior to demolding the wet-cast concrete products, by removing a vacuum on the flexible mold by moving at least one side edge of the flexible mold away from a part of the flexible mold that is adjacent to the at least one side edge in a direction opposite the open side of the flexible mold.
