Press and Sinter (sometimes called conventional processing) is the basic procedure for the manufacture of PM parts. It includes mixing the metal powder or powders with a suitable lubricant and then loading the mixture into a die or mould and applying pressure. This gives what is called a compact which are referred to as green, meaning unsintered: hence the terms green density and green strength. The part will have sufficient cohesion to enable it to be handled safely and transferred to the next stage which is heating. This is usually in a protective atmosphere, at a temperature below the melting point of the main constituent so that the powder particles weld together and confer sufficient strength to the object for the intended use.

For more information on Press and Sinter, EPMA has a short introduction here.
