Abstract
A method of manufacturing a razor blade cutting edge, the method including: applying a single coating of a polymer material to the razor blade cutting edge to form a coated blade edge; selecting a temperature profile, where the temperature profile has a temperature and a time, and wherein the temperature profile is selected based on a composition of the razor blade cutting edge; heating the coated blade edge at the temperature and for the time indicated by the selected temperature profile to adhere the polymer material to the razor blade cutting edge; and optionally treating the coated blade edge with a solvent or a mechanical process to partially remove the coating.
Claims10
A method of manufacturing a razor blade cutting edge, the method comprising:
- applying a single coating of a polymer material to the razor blade cutting edge to form a polymer coated razor blade cutting edge;
- selecting a temperature profile, wherein the temperature profile comprises at least one temperature and at least one time, and wherein the temperature profile is selected based on a composition of the razor blade cutting edge;
- heating the polymer coated razor blade cutting edge at the temperature and for the time indicated by the selected temperature profile to adhere the polymer material to the razor blade cutting edge;
- cooling the polymer coated razor blade cutting edge to a temperature between 68 and 77 degrees Fahrenheit;
- performing a second heating of the coated blade edge comprising a second adhesion step to adhere the polymer material to the razor blade cutting edge,
- wherein the first heating of the coated blade edge comprises a first heating stage and a second heating stage, and
- wherein the second heating of the coated blade edge comprises a first heating stage and a second heating stage.
