Updated Monday, 11th December 2017. A process where loose metal powders are poured into a metal die and vibrated until loosely compacted. When filled, the die is placed inside a furnace and sintered.

What is the sintering process?

Sintering, which is also called 'frittage,' is the process of forming a solid mass of material through heat and pressure without melting to the point of liquefaction. This process involves the atoms in materials diffusing across the particle boundaries and fusing together into one piece.

What is difference between compacting and sintering?

Before any heating takes place in powder metallurgy, a compaction device presses the particles of your metal mix together. ... The sintering furnace applies enough heat to further bond the particles -- but not enough heat to reach the melting point of your alloying elements.
