1. A process for producing a beam guiding grid, including a molding, provided with a grid of passageways and wall areas surrounding the passageways, formed by a mixture of radiation-absorbing metal powder and binder, comprising:
producing the molding by injection molding,
wherein a homogenized mixture is filled, as a flowable prepared injection compound, using an injection machine into a molding tool forming the molding, into which movable mold cores were introduced before the injection compound was filled in.
