1. An inductively heated mold system comprising:
a) first heater module comprising:
i) a mold aperture;
ii) an inductive coil;
b) a mold body assembly configured within the mold aperture and within the inductive coil and comprising:
i) a mold body that is thermally conductive comprising a mold cavity;
a ferromagnetic layer configured around the mold body;
an inlet aperture; and
an extended sleeve configured around the inlet aperture;
ii) an end sleeve plug configured within the extended sleeve;
wherein the ferromagnetic layer is configured to be heated by the inductive coil and wherein the ferromagnetic layer is configured to heat the mold body through thermal conduction; and
wherein the ferromagnetic layer is configured on the extended sleeve, wherein the ferromagnetic layer heats the extended sleeve and wherein the extended sleeve heats the end sleeve plug.
