Sintered parts are precision parts manufactured by press molding fine metal powder in a precision die (powder metallurgy die), which is then hardened by heating (sintering).

Popular for their high material yield rate and high precision, sintered parts are an essential part of the automotive and electrical appliance industries, making it possible to produce complex shapes and mass produce lightweight products.

In the PM process the following three steps are followed in sequence: mixing (or blending), compacting, and sintering.

          Mixing: A homogeneous mixture of elemental metal powders or alloy powders is prepared. Depending upon the need, powders of other alloys or lubricants may be added.

          Compacting: A controlled amount of the mixed powder is introduced into a precision die and then it is pressed or compacted at a pressure in the range 100 MPa to 1000 MPa. The compacting pressure required depends on the characteristics and shape of the particles, the method of mixing, and on the lubricant used. This is generally done at room temperature. In doing so, the loose powder is consolidated and densified into a shaped model. The model is generally called “green compact.” As is comes out of the die, the compact has the size and shape of the finished product. The strength of the compact is just sufficient for in – process handling and transportation to the sintering furnace.
