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.
