1. A method for bonding a wax component in a feeder system, the method comprising:
embedding nano-particles in wax to form a sacrificial susceptor;
coupling the wax component to another component such that the sacrificial susceptor is at an interface of the wax component and the other component; and
heating the sacrificial susceptor to cause the wax of the sacrificial susceptor and at least a portion of wax of the wax component to melt to form a bond between the wax component and the other component.
 
11. A method for bonding a wax component in a feeder system for a lost wax casting process, comprising:
embedding conductive particles in wax to form a sacrificial susceptor;
coupling the wax component to another component such that the sacrificial susceptor is at an interface of the wax component and the other component; and
heating the sacrificial susceptor to cause the wax of the sacrificial susceptor and at least a portion of wax of the wax component to melt to form a bond between the wax component and the other component.
 
17. A wax casting system for bonding a wax component in a feeder system, the wax casting system comprising:
a plurality of sacrificial susceptors each including nano-particles embedded in wax;
a plurality of runners and supports, each of the plurality of runners and supports coupled to the feeder system; and
an inductive heating system;
wherein, each of the plurality of runners and supports corresponds to and is associated with at least one of the plurality of sacrificial susceptors.
