Rajkot has earned its place as the beating heart of India’s investment casting industry. For decades, the region has supplied precision-engineered components to sectors like automotive, pumps, valves, defence, hydraulics, and oil & gas. With 150+ investment casting units and 1000+ foundries operating in and around the city, Rajkot today exports to over 70 countries, strengthening India’s global footprint in metal casting.
But Rajkot’s rise is not just about numbers—it’s about the spirit of innovation driven by local entrepreneurs who understand what the industry needs long before the world does.
Over the last decade, the casting cluster has grown 12–15% year on year, fueled by automation, R&D, and a growing shift from international buyers who now trust Indian suppliers for high-precision manufacturing. And behind this growth are businesses that don’t just make machines—they solve real industry problems.
One such problem-solver is Mr. Bhaven Mehta, the mind behind Amber Engineering Enterprise.
Meet the Man Reinventing Foundry Productivity — Bhaven Mehta of Amber Engineering
Amber Engineering has been a trusted name for abrasive and grinding solutions used across foundries. Their machines—such as Abrasive Belt Grinders, Bench Grinders, Swing Frame Grinders, and Flexible Shaft Grinders—are widely used in casting units across India.
But what truly distinguishes the company is its culture of innovation. Instead of building “one-size-fits-all” machines, the team actively collaborates with foundries to understand their pain points and create custom solutions.
And one challenge kept surfacing again and again:
The Foundry Bottleneck No One Can Ignore: Fettling
Every foundry owner agrees—the fettling department is the biggest productivity roadblock.
Manual grinding leads to:
-
- inconsistent finishing quality
-
- dependence on highly skilled labour
-
- slower output
-
- operator fatigue
-
- high rework and rejection rates
As order volumes increase and timelines shrink, fettling becomes a major bottleneck.
This is exactly the challenge one Rajkot foundry brought to Bhaven and his team.
Turning a Shopfloor Problem Into a Breakthrough Innovation
Instead of offering a temporary fix, Bhaven decided to build a long-term solution. Bringing together his decades of engineering expertise and deep understanding of foundry processes, he partnered with the customer to design a system that could truly transform fettling productivity.
Months of prototyping, testing, and real-world trials led to a breakthrough:
Introducing India’s First Indigenous Semi-Automatic Fettling Machine
Designed specifically for Indian casting units, this machine bridges the gap between manual fettling and expensive robotic systems. It brings automation within reach—without the complexity and high investment usually associated with full robotic setups.
Key Benefits:
-
- Uniform finishing quality across all batches
-
- Reduced dependency on experienced workers
-
- Significantly higher productivity
-
- Safer working environment
-
- Lower rework and rejection rates
-
- Compatibility with various casting shapes and sizes
By blending smart automation with practical usability, Amber Engineering has created a machine that delivers real impact where it matters the most—the shopfloor.
And the response? Rajkot’s foundry community is already showing strong interest.
Why This Innovation Matters for Rajkot — and for India
Rajkot’s iron and casting ecosystem is built on decades of craftsmanship paired with the agility of local engineering entrepreneurs. As global customers demand better finish quality and shorter lead times, modernizing secondary operations is no longer optional.
Semi-automatic fettling machines like this will help foundries:
-
- boost export competitiveness
-
- meet international quality requirements
-
- handle higher production volumes
-
- reduce production costs
-
- improve worker safety and efficiency
Most importantly, it positions Rajkot as a future-ready global sourcing hub—armed with indigenous innovation instead of expensive imported solutions.
This is not just a new machine. It’s a step toward self-reliant, high-precision Indian manufacturing.
What’s Next for Amber Engineering? Another Innovation on the Horizon
Bhaven Mehta isn’t stopping here.
One of the most demanding processes in investment casting is cutting the gating system—or “cutting the tree”—after pouring. This task is slow, labour-heavy, and physically exhaustive.
Amber Engineering is now developing a new Tree-Cutting Machine that promises to slice through gating systems with ease. Currently in the prototype stage, this innovation could become another game-changer for the casting industry.
More details are expected soon—and the industry is already watching.
Foundries Ready to Upgrade Their Fettling Shop? Here’s Your Chance
If your foundry wants to:
-
- increase throughput
-
- reduce dependency on manual grinding
-
- ensure consistent finishing
-
- or simply modernize your fettling department
Amber Engineering is now offering demonstrations, technical details, and commercial consultations for their semi-automatic fettling machine.
The future of smart foundry automation is being built right where the industry’s pulse beats strongest—Rajkot.
And this new innovation is another proud milestone for India’s engineering excellence.
