ABSTRACT:
A method is provided for manufacturing interlocking parts, in which at least one part is manufactured by powder injection molding. To compensate for the amount of contraction of one of the parts manufactured by powder injection molding and, if desired, to produce an additional clearance, a separation layer of plastic material is applied between the interlocking parts. After the injection process to form the separation layer, the separation layer and the binder are removed by a binder-removing and sintering process step. The method is also applicable to powdered metal extrusion for manufacture of double-layered metal parts.
