Zusammenfassung:	A process for joining two or more powder injection molded parts by preparing at least two green parts from a feedstock including a binder and an injection powder. Placing the two or more green part into intimate contact, and maintaining the two green parts in intimate contact at a position with a linkage between the at least two green parts to produce an interconnected green assembly. Placing the assembly under shape retaining conditions, melting the binder of the interconnected green assembly under shape retaining conditions to produce a seamless body. On décrit un procédé de jonction de deux pièces moulées par injection de poudre ou plus en préparant au moins deux parties vertes dune matière première, y compris un liant et une poudre dinjection. Placement de deux ou plusieurs parties vertes en contact étroit et maintien des deux parties vertes en contact étroit à une position avec une liaison entre au moins les deux parties vertes pour produire un ensemble vert interconnecté. Placement de lensemble dans des conditions de maintien de forme, fonte du liant de lensemble vert interconnecté dans des conditions de maintien de forme pour produire un corps sans joint.
