The company Wandel in the German city Rottenburg specialized in electrostatic powder coating about 40 years ago. Today, over 60 employees work in 2-shift operation on an area of over 5,000 m². The chemical pre-treatment of workpieces as preparation for powder coating is just as much a part of the company's activities as complex masking work.
It all started with manual powder coating. In the course of time, the customers‘ requirements for surface quality increased and the workpieces became more complex. Wandel required reliable coating systems with which the company can react flexibly to different customer orders. They invested more and more in automated systems - the choice fell on WAGNER.
After Wandel had already had good experience with WAGNER guns and controls, the company decided on automatic systems with the plastic booths PrimaCube and SuperCube. These meet the increasing requirements for speed and number of color changes and offer a high coating quality.
The automatic gap, height and depth control records the workpiece contours and optimizes the gun distances. This results in a high application efficiency with minimized powder consumption. By using a robot, the degree of automation of the coating process could be increased in most cases so that manual coating is no longer necessary. However, the system has been designed in such a way that a recoater can be used if necessary for particularly complex shapes.
During color change, the injectors, powder hoses and guns are automatically cleaned. The booth can be blown out quickly and easily.
PXS powder centers are used as the central powder supply and color change system. During color change the operator is guided through the process on the touch screen. Short suction distances, fluidization with vibration and integrated ultrasonic sieving allow an optimal powder preparation. The innovative injector technology from WAGNER meets the high quality demands of Wandel with its low-air feeding and high coating efficiency. The change of the long-life collector nozzle is possible in a few seconds and minimizes maintenance time considerably.
By the increasing automation of the production with the coating systems and innovative injector technology from WAGNER the company Wandel sees itself very well positioned to master the challenges of the future.
