Helical Spring – The Core Component in Mechanical Systems
About the Product
A Helical Spring is created by winding a wire into a continuous helix. This fundamental design allows it to withstand forces that attempt to compress, extend, or twist it. They are the most common mechanical springs due to their simplicity, reliability, and highly predictable linear force-deflection relationship. While often used as a general term for compression and tension springs, we focus on producing specialized helical springs in various geometries and materials to meet diverse load requirements across all industries.
- Adaptable for Compression, Tension, and Torsion applications.
- Provides predictable and linear spring rate characteristics.
- Manufactured in various geometries (cylindrical, conical, barrel).
- Suitable for high-cycle fatigue environments.
Darshan Spring Industries designs and manufactures high-quality helical springs in sizes ranging from micro-electronics to heavy machinery components. We ensure precise coiling and stress-relieving processes to maximize fatigue life and load accuracy. Our Helical Springs are used in everything from suspension systems to electrical contact mechanisms, offering high dimensional stability and superior load performance.
