Bonding method for lost wax casting using conductive nano-particles
The patent US12042846B2 outlines a method and system for bonding wax components within a feeder system used in lost wax casting processes. The core of the method involves embedding conductive nano-particles in wax to create a sacrificial susceptor, which is then coupled to another component at their interface. This sacrificial susceptor is inductively heated, causing both the susceptor's wax and a portion of the wax component to melt, thereby forming a bond. The claims detail various configurations, including the use of tapered depressions for the interface, the potential for robotic heating with a 2-axis positioner, and specific materials such as magnetite for the sacrificial susceptor.
Additionally, the patent describes a system that includes multiple sacrificial susceptors, runners, and supports, all designed to integrate with the feeder system. The system is equipped with a robot that features an inductive heating mechanism, facilitating the bonding process. The claims also specify the loading percentage of the sacrificial susceptor and the methods of embedding the nano-particles, emphasizing the versatility and efficiency of the bonding technique in the context of lost wax casting. This innovation aims to enhance the reliability and effectiveness of the casting process by improving the bonding of wax components.
