East of the mold spring selection of high stress, high-speed amplitude, excellent thermal resistance SWOSC-V equivalent material. It has installed small, good elasticity, high stiffness, high precision, production of materials and surface rectangular dichroic coating, beautiful appearance and so on. East Japan Co., Ltd. is currently producing standardized products into smaller mold spring load, light load, medium load, heavy load, heavy load, such as several die springs Caution: 1) To prevent repeated shocks movable breakage, try to use the starting amount of compression. 2) spring mounting surface should be flat, spring axis relative to the mounting surface should be vertical in order to avoid partial load. 3) To prevent bending, be sure to spring for guidance. 4) To prevent foreign material sandwiched breakage, please note the use of the environment. 5) the spring used in tandem, because of the contact surface is unstable and prone to bending phenomena. The combination with a load difference, the spring stiffness of the spring will have a relatively low stress concentration, and thus reduce the service life. 6) nested within and outside of the spring, the spring due to outside interference arising from wear and breakage. Different pressures, the amount of compression will result in different life different, If you need help, please contact, thank you.
