Mechanical systems often rely on precise tension control to maintain balance and stability. Hagens designs and manufactures tension springs in both standard and customised configurations to meet a wide variety of functional requirements. Each spring is carefully engineered according to the required load capacity, tension range, and installation method — ensuring dependable performance across all applications.
When developing a custom tension spring, factors such as material grade, surface finish, and expected fatigue life are defined in collaboration with the customer. This approach guarantees that every spring performs as intended, whether it functions as a high tension spring in industrial machinery or as part of a compact consumer assembly.
Production is carried out across Hagens’ sites in Denmark, Sweden, Hungary, and China, ensuring consistent quality and documentation for global customers. This international setup allows flexible production volumes while maintaining identical technical and quality standards across all facilities.
Quality and testing
Each tension spring must deliver uniform force and return precision throughout its lifecycle. For that reason, Hagens subjects every component to thorough mechanical and dimensional testing. Load capacity, elasticity, and fatigue resistance are verified through repeated extension cycles to ensure reliable performance, even under constant tension.
Surface inspection and finishing are also key steps in production. Depending on the environment, springs may undergo galvanizing, painting, or delta treatment to resist corrosion and wear. Through these processes, every spring meets the same standards of strength and consistency, whether destined for a garage door mechanism, industrial actuator, or agricultural machine.
Integration in industrial design
Tension springs are essential components in mechanical systems where controlled extension and retraction are required. Their compact structure and adjustable load range make them suitable for a broad range of applications — from garage door spring tension assemblies and automotive mechanisms to tools, pliers, and industrial systems.
Engineers often select tension springs to maintain equilibrium or counteract forces within moving assemblies. Their capacity to deliver precise force under varying loads contributes to smoother motion and enhanced durability of the overall mechanism.
In addition, spring tension rods and other related components can be integrated to distribute load more efficiently, allowing flexible design solutions for both small-scale devices and heavy-duty industrial systems.
Durability and lifecycle
A key benefit of Hagens’ tension springs is their durability. Every spring is produced from certified materials sourced from leading steel mills, including EN 10270-1 cold-drawn wire, EN 10270-2 oil-tempered wire for high-stress uses, and EN 10270-3 stainless steel for corrosion-resistant environments.
Advanced alloys such as Elgiloy®, Hastelloy C-276®, and Inconel® are also available for industries operating under extreme conditions. Combined with precise coiling and heat treatment, these materials ensure a long service life with minimal maintenance. This is why these alloys are often used when creating a custom spring.
This durability supports continuous operation in demanding environments — from automated production lines to garage door systems — where reliability and consistency are crucial to safety and efficiency.
Sustainability and responsible production
Sustainability is an integral part of Hagens’ operations. The company’s facilities follow international standards, including ISO 9001, ISO 14001, ISO 45001, and IATF 16949, ensuring that environmental, safety, and quality criteria are met throughout the production chain.
Hagens continuously works to reduce its environmental impact through material recycling, energy optimisation, and responsible sourcing. This commitment supports long-term product reliability while contributing to lower resource consumption and waste generation.
The role of tension springs in modern industry
Across manufacturing, automotive, and agricultural sectors, tension springs play a vital role in systems that rely on precise and repeatable motion. By combining material expertise with advanced production control, Hagens delivers spring solutions that balance strength, elasticity, and endurance.
Whether serving as a high tension spring in a heavy industrial mechanism or ensuring smooth operation in a garage door system, each spring is produced with the same focus on accuracy and performance.
Decades of engineering experience and global production capability make Hagens a trusted partner for customised tension spring solutions — designed to perform reliably, cycle after cycle.
