Abstract: A process for forming an injection molded article including multiple appliques. The process generally includes the steps of: positioning in a mold a first applique including a edge; positioning in the mold a second applique including a terminating end; abutting the second terminating end against the edge in a non-overlapping, substantially perpendicular configuration; injection molding a thermoplastic resin around the appliques to form an article. Because the first and second appliques do not overlap, they will not separate from one another over the life of the injection molded article. Accordingly, multiple applique articles formed according to the process of the present invention maintain their structural integrity and are resistant to warping, peeling and/or separation of the appliques from one another.

Abstract: A method of overmolding a heat pipe includes providing an injection mold apparatus having a cavity, an input gate, a bleed off overflow gate in communication with the cavity and a tubular heat pipe charged with phase change media which is capable of being collapsed by imparting an external collapsing pressure. The tubular heat pipe is placed into the cavity in the injection mold apparatus. A net shape moldable thermally conductive material is introduced into the cavity and around the tubular pipe.
