Abstract: The present invention relates to thermoplastic products. In particular, the present invention relates to systems and methods for heating a thermoplastic product. While the thermoplastic product can include any suitable ingredient, in some cases, it includes one or more electrically-conductive materials, such as iron. Also, while the thermoplastic product can be melted in any suitable manner, in some cases, an inductive heater is used to heat the electrically-conductive material and thereby melt the thermoplastic product. In some cases, the thermoplastic product is configured to be melted on demand. While this can be accomplished in any suitable manner, in some instances, the thermoplastic product is formed into an elongated shape, such as rope, that is fed past a heater, such as an inductive heater, to melt the product. In other cases, the thermoplastic product is melted in a vat that is heated by an inductive heater. Other implementations are also described.
