A tool component, a hot-pressing device and a method for hot pressing preforms from a fiber-containing material are described, wherein the hot-pressing device has a first tool component with a first tool body and at least one first molding device and a second tool component with a second tool body and at least one second molding device. The method includes providing at least one preform made of fiber-containing material, heating the first tool body and the first molding device via a temperature control device, placing a preform on first contact surfaces of the first molding device, moving the second tool component relative to the first tool component, and pressing the first tool component and the second tool component until the first contact surfaces and the second contact surfaces form a closed cavity.
