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...
1. A tire mold comprising: a mold surface including a portion defining a feature having a cross-sectional width of less than 10 mm and an aspect ratio of greater than 1.0, the portion including a region of the mold surface adjacent to the feature; anda conformal coating formed on the portion of the mold surface, the coating comprising a fluorocarbon polymer and having a thickness of less than 25 microns across the portion, the thickness of the coating varying by less than 10 microns across the portion. 2. The tire mold of claim 1, wherein the coating com...
