　　There are often many medical equipment manufacturers who do not know how to choose medical springs when purchasing medical springs. Today, Chuangda Gaoxin will explain to you how to choose medical springs correctly through the following factors. Generally, when selecting a medical device spring, it needs to be determined according to the nature of the load, working environment, temperature, process and other aspects of the spring.

　　First of all, when confirming the shape and size of the material section, it is first necessary to select the size required by the country, and do not select non-standard materials.

　　For the springs of medium and small medical devices, they are mainly spiral tension springs. The strengthened steel wire is the first choice. The lead bath isothermal cold drawn steel wire and the oil quenched and tempered steel wire have very high strength and good appearance. The quality and fatigue performance are higher than that of general quenched and tempered steel wires, which are very simple, the process performance is very good, and the quality is very stable.

　　Carbon cable tension spring steel wire and piano wire will have a very large residual stress after cold drawing. After the tension spring is processed, there may be a very large multiplied residual stress. The size change after tempering is very large, and it is difficult to control the size accuracy. . The oil quenched and tempered steel wire is tempered and strengthened after the steel wire is drawn to the regular size, and basically there is no residual stress. Cold drawn reinforced steel wire.

　　For large and medium-sized medical device springs, cold-drawn materials or cold-drawn polished steel should be used for high load accuracy and stress. For springs with low load accuracy and low stress, hot rolled steel is available.
