Powder Sintering
Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles pressed together in the compact. Bonding within the green compact is weak and this pressed unsintered part usually has just enough structural integrity to be handled. Bonding that occurs during sintering greatly strengthens the part.
