Method of maintaining appearance criteria in laser welded article air induction assembly

Abstract

A method of assembling a plastic article includes laser welding a first laser absorbent part having a first surface finish and a second laser transparent part with a second surface finish that is different than the first surface finish. The first part includes a surface finish that is textured and grained. The second part includes a substantially smooth non-textured surface finish. One of the first and second parts includes a carbon black dye that provides a desired black color. The other of the first and second parts does not include the black dye but instead utilizes another dark colored dye. The carbon black dye provides for the part to be laser absorbent and the other type of dye is utilized to provide a substantially similar appearance in a laser transparent part.
