“Technology alone isn’t enough. It’s our People, rubber technologists, skilled engineers, and quality engineers who make precision part of our culture. They think critically, solve problems proactively, and ensure quality is embedded in everything we do.” Darshan Shah
Harkesh Rubber is known for its customized solutions and achieving exceptional tolerances like ±0.001 inches. Could you elaborate on the company’s “precision journey”?
Darshan Shah: Our precision journey has been a continuous evolution. Achieving tolerances of ±0.001 inches require disciplined engineering, the right technology, and a mindset that always strives for excellence.
We have made significant investments in advanced moulding machines, cryogenic de-flashing machine, and the DOSS visual inspection system to deliver consistency in every product. our batch weighing system and in-house testing lab help in maintaining batch-to-batch consistency.
But honestly, technology alone isn’t enough. It’s our People, rubber technologists, skilled engineers, and quality engineers who make precision part of our culture. They think critically, solve problems proactively, and ensure quality is embedded in everything we do.
How does Harkesh Rubber incorporate advanced manufacturing technologies and materials science into its operations?
Darshan Shah: What truly drives us, is putting our customers first and staying true to our values. Being a family-owned yet professionally managed company allows us to stay innovative while keeping our promise of reliability and integrity at the heart of everything we do.
“Customer first, integrity, innovation, and harmony are our values that guide us in every decision we make. At the same time, we’ve implemented system-driven processes to ensure efficiency and accountability.” Jay Shah
Harkesh Rubber caters to a wide spectrum of industries. Which two or three specific industry sectors—such as Aerospace, Oil & Gas, or Medical & Life Sciences—are currently driving the most significant growth?
Jay Shah: While we serve many industries, flow control, automation, oil & gas and aerospace are currently driving our most significant growth. Over the next 12–18 months, our focus will be on expanding material capabilities, collaborating closely with OEMs, and ensuring we stay ahead of evolving customer needs.
Could you provide some insight into the geographical spread of your manufacturing plants and how their specialized capabilities collectively support your diverse global customer base and ensure business continuity?
Jay Shah: Our manufacturing is based in India, where we have two specialized units, one dedicated to high-precision moulding and the other to compounding. Each unit has its own expertise but operates under the same global quality standards.
This allows us to serve customers across USA, Europe, the Middle East, and Asia. it gives us flexibility, scalability and business continuity, so even in challenging situations, we can deliver consistently.
How do you balance the core long-term vision and values of the founding family with the implementation of modern, professional corporate governance, performance metrics, and system-driven processes?
Jay Shah: Being family-owned yet professionally managed is at the heart of Harkesh Rubber. Customer first, integrity, innovation and harmony are our values that guide us in every decision we make.
At the same time, we have implemented system-driven processes to ensure efficiency and accountability. This blend allows us to innovate while staying disciplined, and above all, it keeps us human in the way we engage with our customers, partners and employees.
What are the next frontiers for Harkesh Rubber’s product development and R&D efforts?
Jay Shah: Our goal is to move beyond being a supplier, we want to be a ‘Trusted Partner’ for precision sealing solutions and to keep delivering challenging seals for demanding customers.
How does Harkesh Rubber approach the idea of sustaining the Theory of Constraints (TOC) in its operations?
Darshan Shah: At Harkesh Rubber, our journey from constraints to conquests didn’t end with achieving results, it evolved into sustaining them.
We learned that sustaining TOC (Theory of Constraints) means building a culture where everyone speaks the same language of throughput, operating expense, and inventory.
Our bottlenecks shifted by investing smartly, automating wisely, and softwares for real-time digital visibility.
Now, our focus is expanding throughput beyond the factory, through stronger marketing, faster NPD, improved customer service, and deeper global connections.
Because at Harkesh Rubber, TOC isn’t just a project, it’s a culture of continuous improvement, sustained by people and powered by data.
