Abstract: A method of manufacturing injection-molded components having complex features is disclosed. Prior methods typically require the use of a three-piece mold system to form an injection molded component having a complex feature, such as a lawn mower hood having a parabolic shaped front. With the development of a new rigid type of reflective material the present method can thereby utilize a two-piece mold system to form an injection molded component having complex features such as a lawn mower hood having a C-shaped open cavity located at the front of the hood.
