Abstract

The invention relates to a process for producing a beam guiding grid (4), comprising a molding having a grid of passageways (40) and wall areas surrounding them, from radiation-absorbing metal powder and binder, especially tungsten powder and binder. Advantageous production is achieved in that the molding is produced by injection molding, wherein the homogenized mixture, as a prepared flowable injection compound, is injected using an injection molding machine into a molding tool (7) that produces the molding, into which movable mold cores (72) were introduced prior to filing with the molding composition.
