<p>The $1 billion-plus Ford Chennai Vehicle Assembly and Engine Plant (CVAEP) at Maraimalai Nagar, near Chennai, has many firsts to its credit. It is the first Ford plant in the world with a single flexible production line to manufacture both petrol and diesel engines. It is also the first Ford facility to run a flexible crankshaft production line, and to have fully flexible cold test, hot test, and dyno test facilities for petrol and diesel engines.<br /><br />The plant, which started its journey in 1999, currently has an annual capacity of 2,00,000 vehicles and 3,40,000 engines. From here rolls out a whole range of products from the Ford stable, including the Ford Figo, Ford Fiesta, Ford Classic, Ford Endeavour, and the Ford EcoSport. <br /><br />Along with the highly skilled workers who have justly made Chennai the motown of India, the state-of-the-art plant also employs about a 100 robots as part of Ford’s green manufacturing initiatives.<br /><br />Start from a blank slate<br />Sheet metal processing marks the first step in the manufacturing process, where coils of steel are levelled, washed, and cut into smaller pieces known as blanks. The blanks are then moved to the stamping (the process of placing flat sheet metal into a stamping press) facility, where they are fed into the line through an automatic feeder and pressed into specific parts — doors, bonnets, roofs, etc.<br /><br />The stamping line features cross-bar technology, and is configured for quick-die changes of less than three minutes, thereby adding flexibility to the production schedule.<br /> The blanking and the stamping facilities each feature two automated lines, which are fully enclosed to ensure noise reduction and dirt protection.

The trolleys are designed to make the efforts of production workers more ergonomically easy, such as reducing bending movements. As the vehicles move through the line, fully dressed engines are delivered in production sequence to the final assembly area, through an overhead conveyor belt from the adjacent engine plant.<br /><br />With quality being a key metric in the Global Ford Production System, all vehicles are put through a range of tests at the end of the final assembly line. This is in accordance with the Global Ford Consumer Product Audit, which evaluates vehicles from the customer’s perspective.<br /><br />The vehicles are also tested extensively on a circuit, which features various road surfaces designed to simulate real-world driving conditions, including straight road, twisting road, cement road, hill-climbing and rural road conditions.<br /><br />Mirroring the best practices from Ford assembly plants around the world, this circuit requires special manoeuvres over bumps and other surfaces. This is used to check vehicle quality and structural robustness before it is shipped, and significantly reduces customer concerns about squeaks and rattles. Currently, vehicles manufactured at CVAEP are exported to over 37 markets from the Chennai and Ennore ports.<br /><br />Safety a priority<br />Safety is Ford’s key priority — be it for the product, or the plant processes. All CVAEP visitors are introduced to the plant safety protocol through an eight-minute video, which lays out the dos and don’ts to be followed during plant walks, and steps to be taken in case of emergencies.<br /><br />Fully covered shoes and full-sleeved clothes are essential on the shop floor, and visitors are directed to designated gangways and aisles in each facility. Protective equipment, including earplugs, goggles, watch covers and belt covers, are provided to visitors, as per the requirement in each shop-floor.<br /><br />“With quality being a key metric on the Global Ford Production System, all vehicles produced at our plant have not only won the hearts of customers in India, but also around the world.
