From this humble beginning the company has grown and transformed itself into a global manufacturer of precision cold-formed and machined components and assemblies. ATF has steadily enhanced its manufacturing capabilities, building a reputation for innovative products, superior quality, highly capable processes and best-in-class customer service.
