Molds for forming formed containers with reduced or eliminated parting lines, and systems and methods of forming the formed containers, using electromagnetic radiation are disclosed. In some aspects, the forming mold includes a multi-segment mold disposed about an electromagnetic coil. The multi-segment mold having a plurality of circumferential segments, a bottom mold section and an annular ring. Each of the circumferential segments including an inner surface wherein the plurality of inner surfaces defines a desired shape of the formed containers. The bottom mold section being adapted to hold and move the pre-form articles about an electromagnetic coil and into and out of the forming mold. The annular ring being adapted to hold, seal and optionally shape a top section of the pre-form articles so as to reduce or eliminate parting lines on the surface of the formed containers.
