Abstract (en)

[origin: WO0006327A3] The invention relates to a method for producing components by metallic powder injection moulding of metallic powder parts coated with a binding agent in an injection mould. According to said method the metallic powder parts of a titanium alloy are used to produce components having a complex shape. During the production of the components, the stages production of the metallic powder parts for the titanium alloy, preparation of the feed-stocks with a binding agent, release of the binding agent and sintering are carried out exclusively in an ultrapure protective atmosphere of protective gas and/or in the absence of air and/or under vacuum. The metallic powder parts and the binding agent ingredients are such that they are poor in impurities. The sinter support for the components is configured in such a way that during sintering of the components the free slip of the surface of the sinter support for the components positioned thereon remains intact.
