Abstract

A pressed powder element forming machine is provided, in which an adjustable core insert is provided in a compression chamber of a machine body and a forming space is provided between the compression chamber and the core insert. A sealing cover is used to close the forming space through a breathable material. When making dry or wet pressed powder element, dry loose powder or wet loose powder is fed into the forming space and the core insert is actuated to press the dry loose powder or wet loose powder into pre-pressed powder blank. Simultaneously, an evacuating power source connected between the sealing cover and the machine body performs air evacuation or solvent extraction from the forming space, so as to press the loose powder into compact pressed powder element. In this manner, production efficiency of making pressed powder element is increased.
