Coil Spring – Suspension and Energy Absorption
About the Product
The term Coil Spring is often used interchangeably with Helical Spring, but specifically refers to those designed for significant deflection, making them indispensable in suspension systems. These springs absorb kinetic energy from road shock or heavy impacts, then release it to maintain stability and ride comfort. Our Coil Springs are engineered for durability, offering high tensile strength and predictable performance under continuous dynamic loading. They are crucial for automotive, railway, and heavy industrial machinery.
- Exceptional ability to absorb and store large amounts of energy.
- Wide operating range suitable for heavy vehicle suspension.
- Available in linear, progressive, and dual-rate configurations.
- Manufactured with high-quality alloy steels for maximum fatigue life.
Darshan Coil Springs are precision-wound using cold or hot coiling techniques, depending on the wire diameter and application. Each spring undergoes intensive heat treatment and shot peening to maximize its operational strength and resistance to stress fatigue. We provide coatings such as powder coating or zinc plating for superior corrosion protection, ensuring a long service life even in harsh environments.
