Development and Engineering of a Fan Shroud Solution for the Automotive Industry
In the fiercely competitive automotive market, OEMs are under intense pressure to improve quality and reduce cost of ownership all while meeting challenging EPA efficiency guidelines. Through our long-standing partnership with a leading carmaker, at Plastikon, we embarked on a project to redesign a fan shroud assembly with the intent of optimizing space, weight, and cost within the scope of lean manufacturing objectives.
The existing design consisted of dual assemblies, the fan shroud and reservoir bottle, which required separate fastening steps to mount inside the chassis. Our team of product development specialists and design engineers systematically explored and refined alternative designs that would assure the best quality, reliability, and safety while optimizing manufacturability, material usage, and assembly.
Our final, integrated design featured a reservoir bottle hot-plate welded into the fan shroud system. Hot plate welding gave us precise control of the melt temperature for producing molecular-bonded welds with outstanding strength. Featuring injection molded, black and natural polypropylene construction, the new fan shroud, when completed, measured 666.4 mm in length x 577.9 mm in width and was produced to within ± 0.1 mm tolerances.
The net results were exceptional. Engineered with four less parts, it requires 8 less handling steps and avoids having to use an assortment of clips, brackets and screws to assemble it into the vehicle. It’s lighter, stronger, and costs 23% less to manufacture than the original. This customer respects us as a catalyst for waste reduction and a partner for implementing Kaizen strategies for continuous improvement.
