Abstract

A method for producing a shell-shaped component and a production system for producing such a component are disclosed. Thee component is produced by a cold gas stream by cold gas spraying. The particles of the cold gas stream are applied to the edge of the component being produced, wherein simultaneously a supporting body is used, which supports the component only at the point of incidence of the cold gas stream. In this way, the form of the component can be shaped by suitably moving the supporting body and the cold spray nozzle, without having to produce a core that fills the entire volume of the shell-shaped component. Thus, the method may be especially economical for small quantities, because the supporting body can be used universally for components of different geometries.
