PROCESS FOR PRODUCING COMPONENTS BY POWDER INJECTION MOLDING |
摘要 |
<p>Process for producing a shaped metallic body from a thermoplastic composition by injection molding or extrusion to form a shaped part, removal of the binder and sintering, wherein a thermoplastic composition composed of a metal powder and a polymer mixture B1) and B2) based on a polyoxymethylene homopolymer or copolymer B1) is used as binder and to remove the binder a) the shaped part is treated with a solvent which extracts the binder component B2) from the shaped part and in which the binder component B1) is insoluble, b) the solvent is then removed from the shaped part by drying and c) the shaped part is treated thermally at from 140 to 200°C in an oxygen- comprising atmosphere, as a result of which the binder component B1) is removed from the shaped part; and also a shaped metallic body which can be obtained in this way.</p> |
