Dürr’s car body curing process offers an enhanced topcoat appearance and maximum process reliability. EcoInCure is a new car body curing process developed by Dürr that heats and cools bodies from the inside. The new oven heating system is said to reduce electrical energy consumption by 25 percent.

A key component in achieving the best possible top coat and maximizing process reliability, the company says, is EcoInCure’s air flow handling. Nozzles with long throw distances heat the inside of the body by aiming through the opening of the windshield. This supports even heating and cooling conditions for the entire body. Heating times for the body are reduced by up to 30 percent and thermal component stresses are reduced.

EcoInCure’s volumetric flows and temperatures can be adapted to different vehicle types, and custom heating and cooling process can be defined for each vehicle type. This is possible by the cyclic mode of operation of EcoInCure and the option to assign a separate unit to each module. EcoInCure uses low flow velocities on the outer skin, which improves the levelling and appearance of the top coat.

The EcoInCure’s oven heating concept is based around a central heat exchanger. Instead of the conventional method using heat exchangers in the circulating air units, mixing flaps are used to feed in the centrally heated circulating air heating gas. According to the company, this makes for faster and more precise adjustment of the circulating air, minimizes the pressure drop and reduces overall total electrical energy consumption by 25 percent.

Half the length of conventional ovens, the new system design saves a significant amount of space by having the bodies pass through it transversely. Integration of the recirculating air units eliminates the need for steel structure.

Each body gets an individual, software-supported quality certificate for the entire curing process. The oven conditions both during burning in of the paint and during hardening of the steel and aluminum can be accurately tracked for crash safety.

iTAC.IoT.Suite, the new generation of production control systems from Dürr, permits continuous digital tracking of the curing conditions for the body. Data is acquired and evaluated using this software solution (previously EcoEMOS).
