The company originally made rackets to fill the orders of foreign customers, and soon began to provide their own designs, and to seek more diverse foreign clientele in order to reduce the constraints of reliance on a limited few. Continued success finally allowed them to adopt their own Kennex trademark as well, while expanding into tennis wear manufacture. Another trademark popular on the American market is Proton, developed by the Chienhung Electronics Company.
