Active in a place like this! Introducing surprisingly many applications that can only be achieved with special springs.
Koei Spring Industry Co., Ltd. is a "specialized manufacturer of custom springs." It pulls in what is extended and pushes back what is contracted. The operation of springs may seem simple, but when conditions such as high temperatures of several hundred degrees or the passage of several decades are involved, the situation becomes suddenly complex. Our special springs are used in various fields, including "valve opening and closing for marine engines," "tension for construction machinery's endless tracks," and "shock absorption for industrial vehicle chassis." Because the energy is generated solely from the shape of the metal, we focus our efforts on the precision of that shape. 【Currently Active in These Areas (Excerpt)】 <Transportation Sector> ■ Aerospace: Pressure vent valve for fuel pipelines ■ Marine: Valve opening and closing for marine engines ■ Construction Machinery: Tension for construction machinery's endless tracks ■ Vehicle: Shock absorption for industrial vehicle chassis *For more details, please refer to the PDF document or feel free to contact us.
