Molds having wear resistant release coatings |
摘要 |
A mold including a cavity the inner surface of which is at least partly coated with a layer selected from a diamond-like film and layers of fluorine and fluorine compounds. The mold is manufactured by a method which comprises placing at least a part of the mold which constitutes the surface portion of the mold cavity in a vacuum film-forming chamber, introducing a hydrocarbon gas into the chamber, ionizing the gas, and then evaporating it onto a desired surface portion of the mold, thus forming a diamond-like film over the mold portion. The mold portion is surface-treated by ionizing a low-molecular-weight fluorine compound into a plasma, forming a fluorine polymer film from the plasma on at least a part of the cavity surface, while applying a bias voltage to the plasma.
