Abstract: A one-piece, seamless food service base is insert molded from a heat and impact resistant plastic. The base is shaped to receive a standard serving plate and includes an integrally molded core. The core is made from a metal or other material that is susceptible to heating through induction heating. In one form, the core is a solid metal disk with strategically disposed bores for molding the base. In another from, the core is a hollow metal disk having a standard wax phase change core. Insulation may also be added above and/or below the core to improve heat transfer and to keep the bottom of the unit cool. In another form, the core is made of graphite and may even be mixed with ceramic to form a composite which may be used for the entire base, alleviating the need for insert molding a separate core and base.
