What considerations does IGW keep in mind when looking at selecting materials for different gear types and applications?

Material for gear making is selected based on several quality criteria keeping end application in mind by the customers.

Usually, material is a choice made by the OEM and we adhere to the same requirement with our state-of-the-art testing facilities.

What separates IGW from other gear manufacturing companies?

What separates IGW from the rest of the gear manufacturing is that it strongly believes in developing employees and their skills.

It continuously focuses on problem solving, improvement techniques, using digital tools, customer focus, leadership, lean management, 5S, teamwork, communication, knowledge sharing among group companies adopting best practices. We are present in each continent with manufacturing plants. Wherever the customer wants us to deliver gears, we do that from the plant close to the customer.

How do you manage factors like gear noise reduction, vibration control, and heat treatment distortion?

Noise reduction is important. To achieve robust gears that are more resistant to wear and no micropitting under high loads, gear honing, fine grinding comes into play. Gear honing ensures quieter gear shifting. Gear honing is also relevant when noise optimization is very important as it is in case of the construction of electric & hybrid engines.

With the growth of electric and hybrid technology, this is becoming necessary. Fine grinding with special stones also helps in reduction of noise. Especially in automotive, if the torque is too low, rattle noise emerges, and if the torque is too high, that will result in gear whine noise. Idler gears are placed between a driving and a driven gear to transfer motion without change of direction or gear ratio. This also helps to reduce noise and vibrations. For heat treatment, there are stringent quality criteria to ensure there is no distortion.

What are your impressions of the overall Indian gear manufacturing market? Please elaborate on some of the common challenges and opportunities that you have faced.

Over the years we have seen that Indian gear manufacturing is a significant and dynamic sector within the broader manufacturing industry.

The entire manufacturing process needs to be sustainable keeping the environment in mind. We see this shaping up a lot in gear manufacturing as well. We create internal targets to achieve sustainability. Apart from global competitiveness, automation, digitalization is now an integral part of the manufacturing landscape.

What lies ahead for IGW in terms of expansion?

IGW entered the Indian market in 2015 by acquiring a controlling stake in a Pune-based gear manufacturing company and completed the 100% acquisition in 2020. Now, the business is established very well on the foundation of “One Team One Goal” focusing on safety, quality, delivery, cost, agility and continually investing in state-of-the-art technologies come up with “speed of new product development” as one of the key strengths.

Having built a successful business, it now looks to expand to the gear manufacturing business in India. We continuously look for acquisition opportunities in transmission gears and motor gears.

Typically, companies with 200 crores of revenue are our interest, and we are open to look at good and niche companies below this threshold, too.

We will continue to keep building business through more strategic opportunities in the Indian market. I think globally consolidation has happened, and the Indian market will not be an exception.
