Abstract:
A method for painting a complex or compound curved three-dimensional surface of a portion of an article. The method comprises providing a paint film; providing sheet metal having opposite major surfaces; laminating the paint film onto a major surface of the sheet metal to form a painted sheet metal laminate comprising a first portion and a second portion; permanently deforming the first portion of the painted sheet metal laminate into a formed portion of the article having a complex or compound curved three-dimensional shape; applying an initial force for securing the second portion of the painted sheet metal laminate during an initial stage of said permanently deforming step; and applying a later force for securing the second portion of the painted sheet metal laminate during a later stage of said permanently deforming step. The later applied force is greater than the initially applied force.
