Method of blow molding and fluorinating plastic containers

摘要

A novel method of blow molding and fluorinating plastic containers carried out in essentially three steps, including blow molding of the container at a first predetermined pressure in a mechanically locked mold with an inert gas, testing the mold for pressure tightness at a second higher level of pressure with an inert gas, and thereafter introducing a fluorine containing gas into the mold at a third level of pressure.
