DIRECT Hot Pressing - Principle
. During DIRECT Hot Pressing, current flows directly through the sintering mould.
. Temperature is consequently generated only where it is needed.
. Use of a sintering mould is possible.
. A green compact is not absolutely necessary
. The sintering cycle is drastically shortened.
