  1. Constant Force Spring: Technical Advantages

    Comments Off on Constant Force Spring: Technical Advantages

    Our know-how in the field of Constant Force Spring dates back to the beginning of the 20th century.

    At Alcomex Springs, we are proud to offer our expertise in the constant force spring, a mechanism that provides a multitude of technical advantages. This innovative solution is more compact and lighter than most other methods of return or retraction, making it an ideal choice for many industries.The constant force spring is designed to provide a smooth and constant load over its entire length of travel, eliminating the need for deadweights, linkages, cylinders, and other systems. This feature alone can significantly decrease the size and cost of devices, making it an attractive option for manufacturers looking to optimize their products.

    Our constant force springs and assemblies are used in countless applications across various industries. For instance, in the aeronautics industry, we develop Jet and cargo door opening and closing assistance systems, which are critical for ensuring the safety and efficiency of air travel.

    In the green energy sector, we are actively working on cable retraction assistance solutions for electric vehicle chargers, enabling more convenient and efficient charging for electric vehicles. We also provide solutions for the POS, defense, equipment, and health industries, among others.

    One of the reasons we differentiate ourselves from our competitors is our ability to produce custom springs and sub-assemblies tailored to meet our clients’ specific needs. Our team of experts is always ready to collaborate with clients, providing guidance and support in developing innovative solutions that exceed their expectations.

    In conclusion, the constant force spring is a versatile and reliable mechanism with many technical advantages that can improve the performance and efficiency of devices across various industries. At Alcomex Springs, we are committed to delivering innovative solutions and outstanding customer service. Contact us today to learn more about how we can help bring your projects to life.

    Spring hinges, self-retracting devices, seat belts, fall arresters, seat tippers, cable retractors, timers, but also use in children’s toys as ecological alternatives to batteries. This is just a brief list of a large number of uses of a separate group of coil springs made of flat (most often rolled carbon steel or high-strength stainless steel) tape. This group includes clock springs, constant force springs and power springs.

    The construction of these three types of springs is visually similar. However, in terms of functionality and application, the springs are fundamentally different. The clock springs with space between the individual turns work without any contact between the threads. The developed force increases during winding and decreases during unwinding. Very often the working range is only within one coil turn. Conversely, constant force springs and power springs are tightly wound on each other and the force is created by partial or complete unrolling. 

    There are very few companies that can produce these springs. Not only the production itself is demanding. However, the manufacturer must also have strong technical know-how and the ability to provide the customer with the necessary technical support, often starting at an early stage of the customer’s idea or development. And very often it is not just the production of the coil spring itself. Part of the development, production and delivery is also assembly into various types of housings in which the springs are located and work in them.

    One of our brand new production plants focuses on the production of these coil flat springs. State-of-the-art production technologies are complemented by a large R&D team, and the considerable logistics capabilities within our large Lesjöfors group allow the springs to be delivered worldwide. Take a look at our flat strip springs.
