The First step in the forming of powder metal parts is the mixing or blending of the powders. The blend of the powders determines many different properties that can be obtained. Many combinations of metals and of metals with ceramics or other materials that can be used as melted alloys are possible. These often give characteristics of heat resistance, frictional properties, heavy weight and hardness that are not obtainable by other methods.
The mixing may be done either wet or dry and an efficient mixer is used to produce a homogenous mixture. The type of mechanical mixer used will depend on the amount of powder handled and a type of powder.
