ABSTRACT.THE DEMAND FOR HIGH PERFORMANCE MATERIALS THAT HAVE TO SUPPORT SEVERE SERVICE CONDITIONS AT A REASONABLE COST HAS BEEN FORCING THE POWDER METALLURGY TO IMPROVE CONSTANTLY. THE MOST RECENT AND MORE IMPORTANT INNOVATION IN THE AREA IS THE PROCESS OF POWDER INJECTION MOULDING. IT HAS BEEN STOOD OUT AROUND THE WHOLE WORLD IN THE PRODUCTION OF SMALL DIMENSIONS PARTS OF COMPLEX SHAPES INSTEAD OF PRESSURE CASTING AND CONVENTIONAL POWDER METALLURGY. THIS WORK REVIEWS THE METAL INJECTION MOLDING TECHNICS AND APPLIES THE LOW PRESSURE METAL INJECTION MOLDING PROCESS TO FAMILIES OF PARTS USING METALLIC POWDER WITH 10 M PARTICLE SIZE. THIS WORK ALSO COMMENTS THE DESIGN AND CONSTRUCTION OF A LOW PRESSURE INJECTION MACHINE AND INJECTION MOULDS.
KEYWORDS: POWDER INJECTION, SINTERING, DESIGN, IRON POWDER, DEBIND.
