Coated in premium quality at reduced unit costs
March 2012 – As general contractor, Dürr is building a paint shop for Tata Motors Limited in India. The plant at the Dharwad location in the state of Karnataka is designed for the coating of small commercial vehicles.
Dürr is responsible for the construction of the entire paint shop, including the application technology. The RoDip M rotational dip coating process is used in pre-treatment and electro dipping, with which more than 20 million vehicles have already been coated in premium quality at reduced unit costs. With this technology, the rotational movement of the car body allows inclined sections at the entrance and exit of the dip tank to be eliminated. Along with saving space, the result of this is also reduced consumption of energy and chemicals due to smaller bath volumes.
In the UBS area six Dürr type EcoRS 16 robots provide the underbody protection. In the two topcoat lines the interior painting of the car bodies is done manually. In the fully automated exterior painting line 15 type EcoRP L033 painting robots are used, whose paint supply system is supplied along with it. The painting takes place with a 3-wet process – in this case the individual paint coats are applied in succession without intermediate drying. The saving of the drying steps reduces the energy consumption in the paint shop.
The entire plant, to which Dürr contributes fully automated skid conveyors, water treatment and the building's air supply and ventilation, is controlled by Dürr's EcoEMOS supervisory control technology.
With this contract Dürr benefits from its long-standing local presence in India with 330 employees. The local engineering expertise acquired through this presence, as well as the supplier base developed over the years, makes it possible to handle a large proportion of the contract locally. This is further facilitated by the fact that the Indian locations are linked by a common IT environment with the other group affiliates. Dürr's own comprehensive project management software is used for order processing.
Starting in August 2012, Tata will produce both light commercial vehicles and passenger cars in this flexible paint shop in Dharwad.
