Pressing pressure of cemented carbide powder divided into two parts in the mould pressing:

1)Net pressure: no friction condition, the pressure that powder be pressed to a certain extent.

2)Side pressure: the pressure that conquers the friction between powder particle and pressing dies called (P2).
