METHOD OF MANUFACTURE OF PARTS UNIT Russian patent published in 1997 - IPC

FIELD: methods of manufacture of parts units by die casting of powdery materials. SUBSTANCE: the offered method includes manufacture of the first part by die casting of powdery material; application of separating layer from artificial material by die casting; manufacture of the second part by die casting of powdery material; removal of binding material and sintering of powdery material. In so doing, separating layer is removed. If thickness of separating layer accurately corresponds to shrinkage value of the second part, the parts are joined by tight fit, and if the layer thickness exceeds the value of shrinkage of the second part, a gap is formed between parts. EFFECT: higher efficiency. 3 cl, 3 dwg
