ABSTRACT:
A process of manufacturing micro or nanostructure surfaces or parts formed of PTFE by applying a vacuum to powered or granulated PTFE in a heated compression mold. The process further includes applying a compression anvil within the metallic mold, removing the mold from a heat source and quenching the mold while maintaining the pressure in the mold during quenching. A mold or mold insert may be manufactured from sintered metal, sintered ceramic or sintered stainless steel to allow the vacuum to be applied across a surface holding the micro or nanostructures.
