Abstract
A method of finishing an enclosure formed from sheet metal includes the step of providing a tube formed from a film of a heat shrink polymer. The enclosure is inserted into the tube. Heat is applied to shrink the tube about the enclosure. Another method of finishing the enclosure includes the step of providing a sheet of a heat shrink polymer. The sheet is wrapped about the enclosure. The wrapped sheet may be affixed to the enclosure mechanically, chemically, or some combination thereof. Heat is applied to shrink wrap the sheet about the enclosure. In various embodiments the heat shrink polymer comprises at least one of the following polymers: irradiated low density polyethylene (LDPE), polyolefin, poly-ethylene terephthalate (PET), poly-vinyl chloride (PVC), and fluoropolymers such as poly-tetrafluoroethylene (PTFE), poly-vinylidene di-fluoride (PVDF), fluoroethylenepropylene (FEP), and perfluoroalkoxy (PFA).
