At the Mauda plant of Hindalco Industries Ltd., the rolling mill had long been a critical part of daily operations—expected to run with precision, consistency, and minimal downtime. 

For a while, everything seemed routine. 

The plant was using a blind shaft incremental encoder from the Kübler brand. On paper, it did its job. But on the shop floor, a different story was unfolding. 

Subtle misalignment issues began to creep in. 

At first, they seemed minor—easy to overlook. But over time, these small inaccuracies started compounding. Every few months, the system would face an unexpected breakdown, bringing operations to a halt for nearly three hours. What seemed like a short downtime had a much bigger impact—interrupting production schedules, reducing output, and preventing the rolling mill from operating at its full potential. 

The team knew this wasn’t just a technical glitch—it was a growing operational bottleneck. 

And that’s where the need for a smarter, more reliable solution began to take shape…

Understanding the Challenge 

The rolling mill was initially equipped with a conventional encoder system that struggled to deliver consistent and accurate feedback. Over time, this led to multiple operational issues. 

The system frequently produced inaccurate position data and incorrect rotation tracking, which directly affected process precision. Additionally, the encoder was installed using a coupling mechanism. While common, this setup introduced mechanical limitations such as misalignment, wear and tear, and instability under high vibration conditions. 

As a result, the plant experienced frequent breakdowns, increased maintenance efforts, and unplanned downtime—ultimately reducing overall efficiency. 

The Need for a Reliable Solution 

To restore operational stability and improve performance, the team recognized the need for a more robust and accurate feedback system—one that could withstand harsh industrial conditions while delivering precise, real-time data. 

This led to the selection of the Dynapar HS35IQPR0GRAAP7PR1 Encoder, a high-performance solution from Dynapar, known for its durability and advanced digital signal capabilities. 

A Smarter Approach to Encoder Technology 

The Dynapar HS35 encoder brought a significant shift in both mechanical design and signal performance. 

One of the most impactful improvements was its direct shaft mounting design, which eliminated the need for coupling. This removed the root cause of misalignment and mechanical failures, ensuring a more stable and reliable installation. 

Beyond its mechanical advantages, the encoder’s digital signal system played a crucial role in enhancing performance. It generates precise quadrature signals that enable accurate position tracking and direction detection. The inclusion of an index pulse provides a consistent reference point, preventing cumulative errors over extended operations. 

Additionally, its differential signal outputs ensure strong resistance to electrical noise—an essential feature in industrial environments with heavy machinery. Even at high speeds, the encoder maintains signal integrity, delivering reliable feedback without interruption. 

The Results: Improved Performance Across the Board 

Following the implementation of the Dynapar HS35 encoder, the Mauda plant experienced a noticeable transformation in its rolling mill operations. 

Position feedback became highly accurate and consistent, enabling better process control. Mechanical failures caused by misalignment were completely eliminated, leading to a significant reduction in downtime. Maintenance requirements decreased, and overall system reliability improved. 

Most importantly, the rolling mill achieved smoother synchronization and enhanced productivity—directly contributing to improved operational efficiency. 

Why This Upgrade Matters 

This case highlights an important insight for modern industries: the quality of feedback systems directly influences machine performance. 

By investing in advanced encoder technology, manufacturers can not only solve existing challenges but also unlock long-term benefits such as improved product quality, reduced maintenance costs, and increased equipment lifespan. 

Conclusion 

The successful upgrade at Hindalco Industries Ltd. Mauda plant demonstrates how the right combination of robust design and advanced digital technology can transform industrial operations. 

With the integration of the Dynapar HS35 encoder, the plant achieved greater precision, reliability, and efficiency—setting a strong example of how smart engineering decisions can drive measurable results.
