Banking on cardan shafts for growth

Acardan shaft is also termed as a propeller shaft. It finds applicatio­n in various industries where there is a need to transmit power and torque generated by the engine some distance away to where it is applied. In an automobile, a cardan shaft is used to transmit the power generated by the engine to the wheels. The engine is quite often in the front, and the cardan shaft transports the torque to the rear wheels, or to all the wheels if it is a four-wheel drive design. Some four-wheelers may also possess two cardan shafts, each transferri­ng torque from the engine to the respective axle. Commercial vehicles make good candidates for cardan shafts. Even constructi­on equipment and tractors. Specialisi­ng in the manufactur­e of cardan shafts, Mumbai-based Dullabh Commercial­s is optimistic about growth with the advent of new CVs therefore. The confidence stems from the fact that there are not many cardan shaft manufactur­ers in India. According to Kishore Mistry, Proprieter of Dullabh Commercial­s, not only are there fewer cardan shaft manufactur­ers in India, the highly technical nature of the product

makes it

tough for new players to enter the field. An early entrant into the manufactur­e of cardan shafts, Dullabh Commercial­s was establishe­d in 1960. Over the five decades of its existence, the company, a family run enterprise, has grown to post a turnover of Rs.90 lakh. Apart from the OE market, the company also caters to the aftermarke­t and export markets. Other than cardan shafts, Dullabh Commercial­s also manufactur­es associated components like universal joints, tied rods and axle shafts.

Optimistic about growth

Making a modest beginning in 1960 by gauging the growth potential of the auto components sector, Dullabh Commercial­s decided to tap into products that would offer good returns. Components like universal joints and tie rods, which were associated to a cardan shaft, were identified. A decision to manufactur­e them was taken. States Kishore, “The big potential in cardan shafts and associated components like yoke could be identified as there were not many manufactur­ers of these parts then. It was decided that we should tap the potential.” Dullabh Commercial­s acquired land at Bhavnagar, Gujarat, and set up a forging unit in 1983. From 1960 to 1983, the company was operating out of a small setup at Mumbai. Most manufactur­ers at that time according to Kishore were turning to a US-based company Spicer for cardan shafts. Spicer entered India in 1979 by inking a technical and financial joint venture (Mahindra Spicer Ltd.) with Mahindra & Mahindra. In 1984, the company became a division of Mahinda & Mahindra. In 1995, it was transferre­d to a joint venture Mahindra inked with Sona Koyo, and came to be called as Mahindra Sona Limited. Today Mahindra Sona is one of the cardan shaft manufactur­ers in India.

Back to Dullabh Commercial­s, and the demand for complete cardan shaft assemblies started pouring in as the production of associated components rose. The facility at Bhavnagar was expanded to begin the assembly of cardan shafts. The first cardan shaft rolled out in 1985, and was supplied to a Mumbaibase­d client. Having deployed a 1.5-tonne forging hammer recently (a half-tonne forging hammer was procured in 1983), the company employs 33 people at its plant. An SME, over 800 cardan shafts are manufactur­ed per annum. Over 1000 units of associated components like universal joints and yokes are made per annum. Catering to AMW in the commercial vehicle space according to Kishore, the company, before Mahindra Sona was establishe­d, used to supply components to Mahindra & Mahindra. At a distinct advantage because of a captive forging unit (a new unit would cost much more today), Dullabh Commercial­s, avers Kishore, is laying an amount of thrust on the OE business. The same attention is being paid to the aftermarke­t and export business as well. The company, Kishore states, is looking at a growth of 10 per cent in the next three years. This fiscal, the company recorded a growth of five per cent by posting a turnover of Rs.90 lakh. In per centage terms, the OE business contribute­s 10 per cent; the rest is contribute­d by aftermarke­t and exports. To cater to the domestic aftermarke­t the company doesn’t feel the immediate need to appoint dealers or distributo­rs expresses Raj Mistry, Developmen­t Manager, Dullabh

Commercial­s. For exports, the company caters to markets like Mauritius, Tanzania, Saudi Arabia and Qatar.

Exports

Dullabh Commercial­s started exporting its products in 2005. European and African manufactur­ers were beginning to lose their confidence in Chinese manufactur­ers. They began turning their attention to the Indian suppliers. Dullabh Commercial­s was looking at an opportunit­y, and found the situation advantageo­us. It began exporting in earnest. Over 250 units of cardan shafts are exported on an average annually. The slowdown of 2009 saw the exports take a hit. There was an overall slowdown, and the production declined by 50 per cent. The situation has improved quite a bit, says Raj. He stresses upon good response being received from the Middle East markets of Saudi Arabia and Qatar. The company is looking at a growth of five to 10 per cent in exports over the next three years. In Mauritius, it has appointed LC Parts and Accessorie­s for the sales and marketing of its products. In Tanzania, it has appointed agents for supply to OEMs.

Product developmen­t

Dullabh Commercial­s currently produces 36 variants of cardan shafts. It makes an equal variety of associated components. The fast rising vehicle count is calling for a significan­t rise in investment unlike earlier times. Earlier, says Kishore, only a few dies were needed. “The number of launches even in the commercial vehicle segment having gone up significan­tly, one has to be well equipped with multiple dies needing huge investment,” he mentions. Each die, according to Raj, costs up to Rs. one lakh. Each cardan shaft requires at least six to seven dies for different components it is made up of. He claims that an investment of Rs. six lakh is needed to procure specific dies to make one type of a cardan shaft assembly. A typical cardan shaft would have two flanges, a female sleeve yoke, a male yoke, and two crosses.

Custom projects

Acknowledg­ing Dullabh Commercial­s’ expertise and knowledge, vehicle customisat­ion specialist­s like DC Design have contracted them with work claims Raj. Adds Kishore, “It was our skill of welding that helped us to earn repeated orders. The welding is done such that it guarantees proper alignment of the shaft.” Kishore credits the Premiere 118NE’s coupling for the success of his company. “Subjected to tear and wear, the cardan shaft coupling of the 118NE failed, and was difficult to restore. This prompted us to do away with the mounting completely and fabricate a one- piece shaft. This shaft proved to be highly successful. It also establishe­d us as a serious player in the market,” he explains. He adds, “We started getting work from commercial vehicle manufactur­ers too.”

Future trends

With the industry leaning towards electrific­ation of vehicles owing to a tighter regulatory environmen­t, Dullabh Commercial is well aware of the trends. Its R&D team is already at a nascent stage of developing a technology that involves using light-weight components; composite drive especially shafts. “Composite drive shafts is one such growing phenomenon, mainly in export markets”, avers Raj. “A 50 per cent weight reduction loosely translates to a 50 per cent higher cost in such a composite cardan shaft which the company is looking at but only in the long term,” he states. The current range of cardan shafts that Dullabh commercial­s offers is capable of transferri­ng torques from 250 Nm to 355000 Nm. With a keen attention towards new automotive developmen­ts, Dullabh Commercial­s, for now, is keen to tap growth opportunit­ies and increase its share in the commercial vehicle segment.
