Constant Force Spring

Constant force spring is suitable for high tension, load does not increase occasions. In use, the inner diameter is usually used to wrap the spring tightly around the drum, with the free end attached to the load, like a counterweight. But it can also be done the other way around, with the free end fixed and the spring itself providing the working force, as in electrical equipment. Constant force springs can produce considerable elasticity because the load capacity can be multiplied if two or more springs are connected back to back or in series. Compared with ordinary compression spring or tension spring, the elastic force is very constant, and can output almost linear elastic force, to ensure that the product will not change due to the change of elastic force in the process of use. In the long and narrow space, the space can be reduced as much as possible, increasing the possibility of product aesthetic design.   

Usually, the outside diameter value of constant force spring is set according to the installation space. Sometimes, when using intermediate shafts, the inside diameter value must also be considered. The general outer diameter of constant force spring can not be greater than the installation space, otherwise it will produce friction effect. Our company has an independent factory site with the building area of 27,000 square meters, the land area of more than 14300 square meters. Product testing equipment is complete, with nano electron accelerator, injection moulding machine, rubber molding machine and other production and manufacturing equipment. Also it has high pressure screening test center, fully meet the needs of product inspection and testing.

Our products, including Constant Force Spring, have passed the ISO 9001:2015 quality management system, the ISO 14001 environmental management system, the OHSAS 18001 occupational health and safety management system, the national production safety standardization certification, the full implementation of the "6S" production management system, and the realization of products with zero defects. We are dedicated to providing customers with stable quality, reliable performance, and high added value high quality products.
