Taking advantage of the features of our integrated production system from the production of functional materials to processing, Suncall develops materials and products that contribute to the requirements of environmental responsibility, safety, and high fuel efficiency for the fundamental components of automobiles, such as engines, transmissions, and parts for safety devices. In order to realize the high reliability demanded by such application, we are striving to manufacture high-precision and high-quality products under a strict quality assurance system. Suncallfs precision functional parts are playing an active role in places not visible to the casual observer in state-of-the-art fields such as small-sized high-output engines, gearless transmissions, and digital steering control. We are also focusing on the development of new products supporting the electronic automation and digitization of automobiles, in line with the evolution of hybrid, on-board terminals.

Our high-precision and low-cost type of ring gears use precision shaped materials processed by our unique blank-shaped ring manufacturing process. Therefore, we can guarantee precise tooth shape and hardening depth. For drive plates, we use inspection devices developed at Suncall for the inline measurement of roundness and flatness.
