1)Constant force spring is made by winding the steel strip into a coil which exerts a nearly constant retraining force to resist uncoiling. By comparing the differences between constant force spring and traditional wire springs, the advantages will be obtain as following:
1.To exert nearly constant force during entire extension.
2.Short initial deflection, it means that reaching the rated load at short extension.
3.Long extension capability
2)Specially ussed as powerplant for monitor lifter system, auto curtaiin system, stretchable earphone, mouse, computer connector, stamping gun, pushing-back goods shelf etc
3)product dimension range thickness:0.03mm-0.75mm ; width:0.5-50mm
4)could produce any wire diameter, any elastic force products according to requirments (For example: elastic force increase with the spring extension, elastic force decrease with the spring extension, elastic force remain the same as the initial force even spriing extension )
