BULLETIN PIF Pneumatic Isostatic Forging An Advanced Densification Technology ADVANTAGES AMETEK's pneumatic isostatic forging (PIF) process extends wrought metal powder fabrication technology, which is used to manufacture light and heavy gauge strip products, to include heavy gauge or thick section stock by: ^ Producing high density in powder metal compacts while preserving or enhancing mechanical and magnetic properties. Providing a near net shape manufacturing technology. Offering a controlled microstructure by trading off temperature against pressure to produce high density. Providing a rapid processing technique for producing high density materials. DESCRIPTION AMETEK's new advanced densification technology combines high pressure forging with a moderate temperature range. This patent pending process provides high density and controlled microstructure for high performance products made from metal, ceramic, or composite powders. This process is known as pneumatic isostatic forging (PIF) and extends AMETEK's wrought powder metallurgical manufacturing technology to heavy gauge materials like rod, plate, and tubing.

The addition of pressure to sintered materials has been available for several years through processes such as low pressure assisted sintering, hot isostatic pressing, and hot forging techniques. All of these pressure assisted processing techniques have had limited success except for very expensive materials or special component applications due to either cost, performance characteristics, and/or limited quantity throughput. PIF provides a solution to these limitations. THE PIF PROCESS (AMETEK's patented process) PIF is used to provide high performance metal powder components by...
