Enkei believes that the water used in the casting, manufacturing and machining processes is crucial in ensuring high quality wheels. Enkei has a separate water filtration facility at each plant to provide a consistent water standard throughout the entire manufacturing process. Filtration helps to eliminate much of the chemicals, minerals and other impurities that may lead to physical and cosmetic quality issues. Filtration eliminates the possibility of impurities inside the water that can clog the machinery, nozzles, etc. which are extensively used in aluminum alloy wheel production. It is an enormous cost to maintain the water filtration, but nonetheless a necessity in maintaining the overall quality for Enkei wheels, which of course benefits AME as well.
