Qianye Spring Co., Ltd.

our company's stainless steel ribbon spring adopts the stretching forming process, which is completely different from the forming process of the traditional spring machine. its processing and forming equipment is also developed and produced by our company, and has also applied for an invention patent in china!its characteristic is that it can produce a very stable constant force spring, that is, after the spring is preset to the required tensile force, the tensile force in the entire stroke after the spring reaches this tensile force remains constant. this effect can be applied to many constant force requirements. among the functional products, such as: constant force springs for carbon brush motors, constant force springs for lifting windows, constant force springs for computer lifting brackets, constant force springs for syringe propulsion, constant force springs for moving up and down of medical equipment, and various testing equipment moving up and down constant force springs for w
