Molds that have coated mold surfaces, as well as methods and components associated with such molds, are provided. The mold surface coatings may be formed of a polymeric material, such as polytetrafluoroethylene (PTFE), and may be very thin (e.g., 50 microns or less). The coatings may facilitate the release of articles formed in the mold and may also reduce, or eliminate, the build up of contaminants on mold surfaces during processing which, thus, increases mold lifetime. The coatings may be formed in a chemical vapor deposition process with process condi...
