Patent number: 10792842Abstract: Systems and methods are provided for molding systems that have a low thermal mass. One embodiment is a first tool that includes a first frame. The first frame includes a first set of plates of magnetically permeable material, and a material disposed between plates of the first set. The first tool also includes a first set of induction coils that are disposed within the first frame and that generate a first electromagnetic field, and a first susceptor that extends from the first set of plates. The first susceptor generates heat in response to the first electromagnetic field.
