WOB - Contract coating of large components

Largest special system for contract coating in Europe

WOB Wessling successful with WAGNER powder coating system - a rising number of customers is switching to cathodic dip painting with subsequent powder coating

At a glance

  • Very high corrosion protection for components with large dimensions: Cathodic dip painting plus powder top coat for workpieces with up to 16 m length, 3.6 m height and 2.6 m width
  • Pre-treatment with special tank for steel, zinc and aluminum
  • In a salt spray test, components with a cathodic dip-paint coating are protected against perforation corrosion for 1.008 hours, while a wet-paint coating will last for only 240 hours
  • Considerably more durable surfaces compared to the application of liquid coating, while also reducing material costs and time effort

Customer challenge

Demand is increasing as a rising number of customers is switching away from wet coating to cathodic dip painting with subsequent powder coating. This procedure – an electrochemical process whereby the object is coated in a dipping bath while DC voltage is applied - offers an extremely high level of corrosion protection, even for complex component geometries and in cavities. WOB-Wessling needs to rely on a powder coating system that guarantees maximum productivity.

Our solution

Three WAGNER powder coating installations are used: two automatic booths, and one manual booth in which up to four coaters can work at the same time – a branch-wide unique feature. Each coater stands on a working platform which can be moved three-dimensionally within the room. Using these systems, WOB-Wessling can coat approximately 1.5 million square meters of powder surface every year. The combination of cathodic dip-paint coating and a double powder coating plus protective varnish leads to considerably more durable surfaces compared to the application of liquid coating, while also reducing material costs and time effort.
