Pressing

 

the use of pressure to process various materials so as to bring about compaction, changes in shape, separation of the fluid phase from the solid, and changes in the mechanical and other properties of materials. Pressing is used in various industries and agriculture and is usually done on high-pressure presses. (The term “pressing” should not be applied to the production of articles and blanks by forging and stamping in forging presses.)

Distinctions are made between various pressing techniques. Thus, in isostatic pressing, fluid under high pressure is used to mold powdered materials in a closed space. In compressed gas, gas is used to mold powdered materials at high pressures and temperatures. In hydrostatic pressing, fluid under high pressure is used to alter the shape of metallic materials by a process analogous to the compression molding of metals. Another technique, pulse pressing, uses explosions, magnetic-pulse processing, or high-voltage discharge in a fluid.
