RoDip® E impresses in China

Bietigheim-Bissingen, December 7th, 2018 – The joint venture FAW-VW is revamping a Chinese paint shop. Plant engineering firm Dürr has been chosen as a competent partner for this task. Once the paint shop is put into operation in September 2019, it will be the first time that the RoDip® E rotational dip process with electric drive has been used in China.

Well over 10 million bodies per year worldwide are already coated with this tried-and-tested technology from Dürr. It does away with the need for entry and exit inclines, which reduces the dip tank length by up to 6 meters and as a result saves water and chemicals. The smaller tank volumes also reduce the amount of energy required for tank conditioning. RoDip® not only reduces the unit costs, but at the same time offers outstanding corrosion protection through an optimized immersion, flooding, and draining process.

Up to now, customers in the Chinese market have preferred the mechanical RoDip® M variant. The electric RoDip® E version is now being used for the first time in China, replacing an existing rival product. RoDip® E impresses with its electric drive, in which each of the freely programmable trolleys contains not only the conveying drive, but also a separate drive for the rotation. The individually programmable trolleys enable optimized dip curves for the respective body. This in turn results in even better coating quality and increased energy efficiency, and thus enables a further reduction in unit costs.

In addition to exchanging the conveyor technology in the pretreatment and electrocoating areas, Dürr is also modernizing the conveyor technology in the adjacent areas. The oven and cooling zones as well as the PVC workstations are also being extended. The aim is to increase the capacity to 65 units per hour and to integrate a new, larger vehicle model into the production process.

Reiner Schmid, CEO of Dürr in China, on this modification: “In addition to the increase in capacity, this modernization will benefit the customer through lower maintenance costs, simpler operation, and higher plant availability.”
