    Abstract: A system and method are provided for using magnetic elements to secure thin wires precisely in an injection molding process in a manner that matches a three-dimensional shape of the an injection molded product produced by the injection molding (overmolding) process. The thin wires are substantially immobilized in a manner that is designed to generally overcome the tendency of the thin wires, which have little mechanical strength, to normally deflect during an injection molding process by employing the magnetic forces produced by embedded magnets. Magnets are integrated into either the cavity or core of a mold structure and the thin wires are placed on those magnets to keep the wires in place during an injection molding process that allows the thin wires to be overmolded. A balance of the core and/or cavity of the mold will be formed of a non-magnetic material.

    Abstract: A fabric mold liner includes a flexible fabric substrate and bounded regions of cured binder encapsulating fibers of the fabric substrate and carrying magnetically attractable particles. A liquid containing ferrous particles in suspension in a binder is deposited on the substrate in discrete, selected regions arranged to correspond to magnetic liner retention points in a mold cavity. The mold liner is used in molding a foam article. The liner is inserted into a mold cavity with the liner positioned such that the bounded regions carrying the binder align with magnetic liner retention points of internal surface. A foamable resin is introduced into the mold and is caused to expand to fill the mold cavity and cover an exposed surface of the liner, such that the liner becomes bonded to, and becomes a part of, a foam body formed by the resin.
