Process for the production of a component by metal powder injection moulding of metal powder mixed with a binder, where individual components of the component are manufactured as separately moulded green body subcomponents and subsequently debinded brown compact subcomponents (5, 6), which are assembled to give a two- or multipart brown compact and are sintered in the assembled state, where the brown compact subcomponents (5, 6) experience shrinkage in the sintering procedure, characterized in that - at least one of the brown compact subcomponents (5, 6) to be connected undergoes a pre-sintering procedure during which it experiences a first shrinkage, - the at least one pre-sintered brown compact subcomponent (5, 6) and at least one further, non-pre-sintered brown compact subcomponent (5, 6) are assembled to give a two- or multipart brown compact, and - the two- or multipart brown compact subsequently undergoes a main sintering procedure, where during the main sintering procedure the at least one pre-sintered brown compact subcomponent (5, 6) experiences less shrinkage than the at least one further, non-pre-sintered brown compact subcomponent (5, 6), and thus the at least one pre-sintered brown compact subcomponent (5, 6) and the at least one further, non-pre-sintered brown compact subcomponent (5, 6) become firmly connected to one another, - wherein, a pre-sintered brown compact subcomponent (5, 6) and a further, non-pre-sintered brown compact subcomponent (5, 6) are connected to one another before the main sintering process via connecting elements (7, 8) which are formed on joining surfaces of the brown compact subcomponents (5, 6) to be connected and engage in one another in a form-fitting manner, and where the brown compact subcomponent (5, 6) to be pre-sintered has, before undergoing the presintering procedure, dimensions such that it cannot be connected to the further, non-pre-sintered brown compact subcomponent (5, 6), and shrinks during the pre-sintering procedure in a manner that permits connection of the two brown compact subcomponents (5, 6) by way of the connecting elements (7, 8) that then interlock. - at least one of the brown compact subcomponents (5, 6) to be connected undergoes a pre-sintering procedure during which it experiences a first shrinkage, - the at least one pre-sintered brown compact subcomponent (5, 6) and at least one further, non-pre-sintered brown compact subcomponent (5, 6) are assembled to give a two- or multipart brown compact, and - the two- or multipart brown compact subsequently undergoes a main sintering procedure, where during the main sintering procedure the at least one pre-sintered brown compact subcomponent (5, 6) experiences less shrinkage than the at least one further, non-pre-sintered brown compact subcomponent (5, 6), and thus the at least one pre-sintered brown compact subcomponent (5, 6) and the at least one further, non-pre-sintered brown compact subcomponent (5, 6) become firmly connected to one another, - wherein, a pre-sintered brown compact subcomponent (5, 6) and a further, non-pre-sintered brown compact subcomponent (5, 6) are connected to one another before the main sintering process via connecting elements (7, 8) which are formed on joining surfaces of the brown compact subcomponents (5, 6) to be connected and engage in one another in a form-fitting manner, and where the brown compact subcomponent (5, 6) to be pre-sintered has, before undergoing the presintering procedure, dimensions such that it cannot be connected to the further, non-pre-sintered brown compact subcomponent (5, 6), and shrinks during the pre-sintering procedure in a manner that permits connection of the two brown compact subcomponents (5, 6) by way of the connecting elements (7, 8) that then interlock.
