MMD Heavy Machinery promotes in-house manufacturing to power global OEM supply chain

By Staff Report June 5, 2025 7:55 pm IST

MMD Heavy Machinery plays a key role in supplying the wear parts required by its group of companies. Subhajit Chaudhuri tells us about their in-house production process and local sourcing focus for precision, agility, and quality across complex, large-scale industrial projects.

How is MMD Heavy Machinery evolving its manufacturing capabilities to meet the demands of global OEMs? 
We built our state-of-the-art manufacturing facility on 15 acres of land in Sricity, Tada, Andhra Pradesh, to meet the spares and wear parts demands for our group companies across the globe. The facility has complete infrastructure to support in-house machinery, fabrication, assembly, etc.

Given the scale and complexity of your projects, how do you maintain agility in your supply chain while ensuring quality and delivery timelines?
From concept to completion, we tailor our full range of services to suit projects of different scales and varied complexity. Our teams are present to support global groups with in-depth OEM knowledge. Our project team always extends their full support to complete the project within the committed timelines. Our holistic thinking and partnership philosophy help us identify the ideal solution for efficient, ecological operation and low total cost of ownership within the timescale. We have completed projects for clients, providing expertly developed comparative project studies, budgetary evaluation within the committed timeframe and technical overviews.

What advanced manufacturing technologies, like modular fabrication, automated welding, or digital twins, are you adopting to enhance precision and reduce cycle times?
Most of our IPSC (In-Pit Sizing and Conveying Technology) solutions are delivered with a skid-mounted (modular fabrication) structure to minimise the site civil activities, with almost no welding at the site due to safety and precision of alignment during the assembly works at the site. We also use Robotic Arc welding at Group Companies. MMD has been producing semi-mobile IPSC units since the early 1980s. It is generally fed by a small fleet of trucks transporting material short distances from the mine face. The Sizer™ unit reduces material in preparation for efficient conveyor haulage out of the mine. Concrete or reinforced earth walls – typically required for fixed plant installation – can cost anywhere from hundreds of thousands of dollars to millions, depending on the scale of the operation. What’s more, they take time to establish and require a lot of natural resources to complete. In contrast, the Semi-Mobile Sizer Stations are designed to work with fabricated twin or single-truck bridges or natural in-ground hoppers, which are much more cost-effective. Rather than positioning the plant away from the bench, the truck bridges can be tied into or adjacent to the bench, thus simplifying installation. As the mine continues to develop, the Sizer stations with bridges can easily be relocated to different areas to limit the overall haulage distances and minimise infrastructure costs.

How do you adapt your manufacturing processes to meet varying compliance and material standards when localising for international clients?
We are the manufacturing and supply hub for the group of companies’ wear parts requirement, and we strictly adhere to our Group’s standard quality procedures and standards. Our customers expect the best, and we deliver. We are committed to integrating only the highest standards across all aspects of our operations, products and services. Through a rigorous and exacting strategy, MMD implement quality management systems and design process standards to deliver consistent products and services. The MMD culture is one of innovation and continual improvement throughout the business. The ISO 9001 Quality Management System accreditation and OEM standards ensure we maintain only the highest standards of quality and service. We employ many design standards during the development of our design work. They also demonstrate our commitment to safe, healthy and sustainable work.

With the growing demand for indigenisation and reduced reliance on imports, how are you strengthening your in-house manufacturing and local vendor ecosystem? How do you source your raw material?
We do most of the plate and structural fabrication in-house by engaging our competent and dedicated manufacturing team, except for a few critical components. For electrical BOI, we source locally.
