CONVENTIONAL PM PROCESS Also known as press-and-sinter, the process consists of mixing elemental or alloy powders with lubricants or additives to produce a homogeneous mixture. Additives may help improve machinability, wear resistance, or lubricity of the part; compacting the mixture in a die at pressures typically as low as 138 MPa (10 tsi) or as high
ADVANTAGES OF POWDERED METALLURGY Powder metallurgy is a well- established mass production method for structural parts, bearings, filters, tool parts, magnets, friction materials, contact elements and components from refractory metals. Its basic steps are powder production, mixing, molding into shapes, and sintering. Optional steps such as sizing, coining, repressing and re-sintering, forging, or
WHEN TO USE PM When to use PM is a commonly asked question. As you would expect there is no single answer, but here are some general guidelines.To make a PM part requires tooling. The cost of the tooling depends on the size and complexity of the part, but can range from
WHAT IS PM? Powder metallurgy-or PM-is a state -of-the-art metal-forming process used to produce net-shape components. Made by mixing elemental or alloy powders and compacting the mixture in a die, the resultant shapes are then sintered (heated) in a controlled-atmosphere furnace to bond the particles metallurgically. Basically a “chipless” metalworking process, PM
