CI-Gabriel manufactures, distributes and supplies the automotive market with ride control products (shock absorbers, struts and gas springs). It also sells directly to consumers in the aftermarket throughout Southern African. Approximately 10 000 units are manufactured daily to meet demand. During the manufacturing process, tubular parts are machined, and welding is performed on these parts. Before these components can be painted and assembled, they need to be cleaned to remove dirt, loose metal pieces and contaminants. The washing machines that GI-Gabriel currently employs do not remove these contaminants sufficiently. Flownex was used to simulate flow rates and pressure of water at the nozzles to ensure correct design changes were made and optimal cleaning achieved.
