Abstract
A pressing method and a finished product thereof are provided. The pressing method includes the steps of: providing a heat conductive base (1), and defining a pressed zone (10) on the heat conductive base (1); forming a plurality of penetrated holes (100) arranged with intervals in the pressed zone (10), and forming a pressed part (101) between any two of the adjacent penetrated holes (100); and processing a pressing and extruding operation to the pressed part (101) for allowing the pressed part (101) to be pressed and extruded so as to be extended and deformed towards the adjacent penetrated hole (100) for filling the penetrated hole (100).
