Manufacturing process of beam guide grid and beam guide grid manufactured using this method

摘要

The present invention relates to a process for manufacturing a beam guiding grid (4) comprising molding from a radiation-absorbing metal powder and binder, in particular tungsten powder and binder, with a grid of passageways (40) and a wall area surrounding them. will be. The molding is prepared by injection molding, and the homogenized mixture is injected as a flowable ready injection composition, using an injection molding machine, into a molding tool 7 for making said molding, and before being filled with a molding compound, a movable mold core 72 ) is introduced, advantageous production is achieved.
