powder metallurgy
Powder Metallurgy is a manufacturing method in which metal powders are compacted in the desired shape and then sintered to form solid-state metal components. It aims at high-precision components with minimal consumption of materials to make the components and has a wide scope for use in making small complicated parts.
Key Features:
- Powder Compaction: Metal powder is pressed in molds under extremely high pressure in order to give the intended shape to the part.
- Sinter Process: The concentrated pieces are heated up to just below the melting point and thus joins the particles together and increases their hardness.
- Material Efficiency: It does away with the excessive raw materials hence it is cheaper and environmental-friendly.
The object is to manufacture fine metal parts in large numbers with high internal quality and uniformity and thus extends its use in industries like automotive, aerospace, and electronics. It has improved its precision an application area further with developments in powder blending and additive manufacturing.
