The spring manufacturing industry has changed dramatically over the decades. Today, it is no longer enough to simply produce components to specification. Customers expect tighter tolerances, longer fatigue life, faster turnaround times, and greater customization. At the same time, manufacturers must navigate raw material volatility, the introduction of new alloys, and increasing certification requirements.
At Sarang Spring, these realities are not viewed as pressures but as responsibilities. Continuous material research, in-house feasibility validation, and disciplined investments in automation allow the company to maintain consistency even as demands grow more complex. Precision is not treated as a final checkpoint. It is embedded into the process from the very beginning.
Scaling with Systems, Strengthened by Legacy
Sarang Spring was founded in 1969 by the grandfather of Isha, Gajkumar Kothadia, who began his journey as a blue-collar worker in a spring manufacturing unit in Germany.
There, he learned the craft from the ground up, developing a deep understanding of materials, machine discipline, and manufacturing accuracy. When he returned to India, he established Sarang Spring with the mindset of a craftsman determined to build something dependable and enduring.
His son Sarang Kothadia later strengthened the company with operational focus and integrity-driven growth. For Isha, the company was never simply a workplace she entered professionally.
From her early teenage years, her vacations and internships were spent inside the factory, observing production lines, understanding client expectations, and learning the rhythm of the shop floor. The business became part of her upbringing long before it became her responsibility.
Over the years, Sarang Spring has built expertise in manufacturing compression, tension, torsion, and shock absorber springs for industries where performance cannot fail. While the automotive sector remains central, the company also supports applications in electrical equipment, oil and gas, renewable energy, aerospace, and medical systems. Each application requires careful consideration of load behavior, operating conditions, and material durability.
Beyond manufacturing capability, the company places strong emphasis on relationships. Isha reflects on how her father often spoke about word-of-mouth and long-term trust. At one point, she viewed this as traditional thinking in a modern marketing world. With experience, she realized that sustained growth in manufacturing is built on consistent communication and reliability. Clients who began working with the company during her grandfather’s and father’s time continue their association today, often recalling not only their technical expertise but also their kindness and approachability. Professional engagements gradually evolved into enduring partnerships rooted in mutual respect.
Every design, every material choice, and every process is approached with the intent to deliver long life, reliability, and trust
Precision Shaped by Experience and Partnership
As the industry advances, automation and system-driven processes play an increasingly important role. The more refined and structured the production line becomes, the greater the efficiency and repeatability achieved. In spring manufacturing, time saved translates directly into stronger competitiveness, but speed without discipline has little value.
Sarang Spring continues to strengthen its operations through advanced CNC machinery, controlled processes, and robust quality systems aligned with global standards. The focus is not merely on expansion but on building an organization that can scale while maintaining consistency.
Looking ahead, the company remains committed to deepening its material research capabilities, investing in intelligent automation, and strengthening system-based operations. The goal is to grow responsibly, remain adaptable to changing application demands, and preserve the values that have shaped the organization for more than five decades.
As Isha Kothadia expresses, every design, every material choice, and every process is approached with the intent to deliver long life, reliability, and trust.
