Powder / powdered metal parts are manufactured by use of
pressure and heat to form precision parts and shapes from molds or dies. The
process requires a precision mold or casting tool / die which is filled with the
metal powder, then the powder is compressed while at ambient room temperature to form or
fill out the die shape. Next, this compressed powder shape is removed from the
compression press and processed through a high-temperature furnace.
Processing the powdered metal part through the high-temperature
furnace is called sintering, and the process fuses the powder metal particles
without actually melting the particles. Following the sintering step, the
rough as-manufactured part further processed using other manufacturing
processes, such as; CNC machining, turning, grinding, etc.
Powder / powdered metal parts are made from materials, such as,
lead, iron, or gold, or special powder alloys. Pre-manufactured power
material may be mixed with die lubricants or graphite to enhance the performance
of the powdered metal part.
Common powder / powdered metal parts in use are gears, bushing,
bearing housing, automotive parts, motorcycle parts, electrical parts, sewing
machine parts.
