ebinghaus0619Components that are to be coated in the KTL process are generally hung or plugged into special devices before they are immersed in the various baths. In addition to constructive measures in the design of the workpieces, the construction of these product carriers also contributes to a good coating result. That is why Ebbinghaus Styria Coating pays particular attention to the design and manufacture of these product carriers.

In the automotive industry and also in other industries, the developers are striving to design parts in such a way that weight or space can be saved, for example, thanks to advanced manufacturing processes. Due to this fact, the geometries of the parts to be coated are becoming increasingly complex and can often no longer be coated correctly with product carriers that consist of simple hook bars.

Leakage behavior of the substrate is important

The positioning of the components therefore also requires very individual and sometimes very complex hangers in order to place them in the correct position in the product carrier. The top criterion here is the run-out behavior of the substrate. A carryover of process media in the so-called creative areas must be avoided in any case, so that there is no reduction in quality. Likewise, places where air bubbles can form must be avoided and parts falling or floating in the process must be prevented.

At Ebbinghaus, particular attention is paid to the cost-effective positioning of the substrates in the product carrier. The trend in goods carriers is increasingly towards clamping or plug-in devices in order to prevent the parts from swinging, which ensures the exact coating position of the parts and usually enables higher loading in the goods carrier.
