“ Our products , which we produce at the Lehrte plant , have a very high variance . We went to the lab with reference components that reflect our broad spectrum . We cross-referenced the results and discovered that Nordson delivers the most advanced coating results . On the one hand , this related to the coating thickness , which was the highly uniform , and on the other hand , the component geometries , which are difficult to coat ,” reports Johannes Reimer , production manager at Miele & Cie . KG in Lehrte .
The powder coating system consists of the standard ColorMax3 fast color change booth , the Spectrum ® HD powder feed center and PowderPilot™ HD control system , eight Encore ® HD automatic guns , after filter and twin cyclone . The system was installed at Miele in March 2021 .
“ We had a very ambitious schedule for the entire project ,” says Andreas Eichbaum , “ partly because we replaced the system
The doors of the washing machines were traditionally always coated manually and could be converted to automatic coating by the new coating system .

With this campaign , Miele is also sending out a clear signal against the throwaway mentality , as Miele products are distinguished by outstanding quality and durability .
during ongoing operation . It turned out that we ran production in two shifts per day , and in the third shift the system was converted . The coordination with the team of Nordson went very well both leading up to and during the two-week set-up phase . In the third week , the first programs were tested , the system was ramped up , and we were able to start a trial run relatively quickly . We had a very clear schedule and after a total of six weeks we went into series production as planned . We were very well supported by Nordson the whole time and the assembled system , delivered and commissioned , fully met our requirements .”
The Customer Benefit : maximum process control
The new powder coating system is used to coat several hundred different components which are always recurring . Corresponding coating programs have been set up for the surface finishing of the component
Coating of very depth components is now simplified and reduces powder consumption .
clusters , which always achieve the same precise results with repeatability . Maximum process control is made possible by the dense phase transmission of the powder , so that programs only have to be created once for the different components . Similarly , coating deep recess components has become much easier due to the soft powder cloud of the HDLV ® dense phase technology . The products are not only coated on the front , but also the top and side surfaces are coated as well . “ The door on our washing machines is a very important component , also for the end customer . This was always a component , which was traditionally coated manually . Now with the new system , we have succeeded in completely automating the powder coating ,” says Andreas Eichbaum about his initial experience with the new powder spray system . “ On the one hand , this is due to the fact that the component has to be coated from both sides and it has very deep geometries on one side , which makes it difficult to electrostatically charge the component . Due to the soft powder cloud , both sides of the component are coated with the required uniform coating thickness from now on ,” and he concludes , “ The powder spread has been significantly reduced compared to before , which of course also saves a lot of powder .”
