The new large-scale electroplating facility of Nehlsen-BWB Flugzeug-Galvanik Dresden GmbH & Co. KG for aircraft parts sets forward-looking standards in the areas of anodizing, hard anodizing, chromating and coloring. The 54 ultrasonic systems from Weber Ultrasonics in the plant's degreasing and rinsing baths make a significant contribution to this.
REQUIREMENTS - QUALITY, CAPACITY AND PROCESS STABILITY AS WELL AS SIZE OF COMPONENTS
The company, which is part of the Swiss BWB Group, has been a partner to the aerospace sector and industry for many years and has numerous certifications. Its requirements in terms of quality, capacity and process stability as well as the size of the components to be treated in the new electroplating plant are correspondingly high. Holes, undercuts and scooping geometries pose a particular challenge for the workpieces to be electroplated. Depending on the component, these areas may contain residues of processing media that are difficult to remove and that often required manual, time-consuming and cost-intensive pretreatment and posttreatment in the previous systems.
SOLUTION APPROACH - LARGE PLANT FOR PARTS UP TO 5,000 X 1,800 X 800 MM IN SIZE
K Galvanik implemented a fully automatic anodizing plant for its client. With 47 baths for parts measuring 5,000 x 1,800 x 800 mm, it meets all the requirements for sustainability, economy and occupational safety. Instead of three plants, as was previously the case, all treatments can be carried out here in just one plant. In addition, it enables higher capacity as well as process flexibility, so that additional market segments can be covered. The new electroplating system was installed in the renovated hall in two rows, each approximately 50 meters long and 15 meters wide.
ADVANTAGES:
High cleaning quality due to homogeneous sonication of the parts
Continuous monitoring and fully automatic adjustment of all process parameters
Additional market segments can be served with only one system
Optimum coordination of ultrasound, temperature and medium allows the sonication time to be reduced to less than two minutes. Fully automated process without manual rework.
