1. A multiple temperature-control process for components that comprise different materials with different magnetic and thermal properties, comprising:
heating magnetic parts of a component primarily by induction to a target temperature;
simultaneously heating non-magnetic parts of the same component primarily by infrared radiation to the target temperature;
simultaneously finely adjusting and/or maintaining the target temperature of the component by convection heating.
