Major Indian auto component manufacturers are diversifying into high-margin services and advanced manufacturing technologies to combat rising costs. With profit margins under pressure, companies like Amara Raja, Belrise, and Motherson are launching new business models and efficiency tools to secure long-term competitiveness.
Indian automotive component manufacturers are undergoing a strategic transition, moving beyond traditional manufacturing to adopt high-margin services and advanced technologies. This shift comes as companies face intense pressure on profit margins due to volatile raw material costs and the need for greater operational efficiency.
Amara Raja’s Pivot to Services
Amara Raja Energy & Mobility is diversifying its revenue model by entering the automotive service sector. The company has approved a ₹100 crore investment to launch a wholly owned subsidiary in Telangana, which will operate under the 'Amaron Assist' brand. This new venture focuses on vehicle maintenance and mobility assistance, aiming to create a recurring, less volatile income stream that complements its core battery business. This move is significant as the company balances this service expansion with its larger, capital-intensive push into battery pack and LFP cell manufacturing, which involves a massive ₹2,320 crore investment. For investors, these simultaneous projects represent a dual approach: securing current cash flows through services while scaling for the electric vehicle future.
Efficiency Through Advanced Manufacturing
To improve margins, other suppliers are focusing on production efficiency and lightweight components. Belrise Industries has entered a technical agreement with Japan’s Yamato to manufacture resin-based air intake manifolds. By replacing traditional metal parts with resin, the company helps automakers reduce vehicle weight, which is a key priority for improving fuel efficiency.
Similarly, Samvardhana Motherson International is leveraging its Singapore arm to industrialize 'Spinheat,' a magnetic induction curing technology developed with Nanyang Technological University. This technology is designed to replace traditional oven-curing methods, potentially reducing the time required for component coating from 24 hours to just one hour. If successfully scaled, this could significantly lower energy consumption and inventory costs for assembly lines, providing a direct boost to operating margins.
The Road Ahead for Investors
While these initiatives aim to improve profitability, the path to implementation carries risks. The automotive component sector continues to face margin compression driven by rising raw material costs, as evidenced by Amara Raja’s recent performance, which saw a 44.8% decline in consolidated net profit for the second quarter. Furthermore, new manufacturing technologies like Spinheat require careful execution to prove their reliability at a commercial scale.
Investors may monitor these developments by tracking the actual commissioning of service subsidiaries, the contribution of new product lines to revenue, and management commentary on margin recovery. The long-term success of these pivots will ultimately depend on the company's ability to successfully deploy these technologies without incurring excessive cost overruns, especially as the industry navigates broader sector headwinds and volatile input pricing.
