A method of manufacturing a hot-runner component includes providing a laser assembly, manufacturing a hot-runner component portion of a metallic material, introducing a property enhancing material to the hot-runner component portion, melting the property enhancing material onto the hot-runner component portion using a laser beam emitted from the laser assembly, and solidifying the melted property enhancing material on the hot-runner component portion. L'invention porte sur un procédé de fabrication d'un composant de canal chauffant, qui comprend la disposition d'un ensemble à laser, la fabrication d'une partie de composant de canal chauffant en un matériau métallique, l'introduction d'un matériau d'amélioration des propriétés dans la partie de composant de canal chauffant, la fusion du matériau d'amélioration des propriétés sur la partie de composant de canal chauffant à l'aide d'un faisceau laser émis par l'ensemble à laser, et la solidification du matériau d'amélioration des propriétés fondu sur la partie de composant de canal chauffant.
