Abstract (en)
[origin: EP4252922A1] A lacquer basin (12) for a dip coating device (10) is provided. The lacquer basin (12) comprises an inlet section (12a) arranged at a lower end of the lacquer basin (12) and adapted to receive a stream of a lacquer mixture (14) injected into the lacquer basin (12). The lacquer basin (12) further comprises a process section (12b) adjoining the inlet section (12a) at an upper end of the inlet section (12a), wherein the process section (12b) is adapted to provide a process volume for dip coating one or more objects in the stream of the lacquer mixture (14). The lacquer basin (12) is characterized in that it comprises a diversion element (22) arranged at or near a transition from the inlet section (12a) to the process section (12b) and adapted to divert at least a part of the stream of the lacquer mixture (14) such as to reduce or avoid turbulences of the stream of lacquer mixture (14) in the process section (12b). Furthermore, a dip coating (10) device and a use of a diversion element (22) is provided.
