The present invention relates to a system (1) and a method for coating a surface (3a) of an object (3) with a spray coating tool (2) spraying atomised coating particles (10) onto. A conditioning hood (20) is applied defining a spray chamber. In operation the spray coating tool (2) is mounted at a coating tool mounting end (21), and an output end (22) is positioned in proximity of the surface (3a) of the object (3) to be coated. The spray coating tool (2) is operated to spray atomised coating particles (10) which travel from the coating tool (2), through the spray chamber and the output end (22) to the surface (3a) of the object (3). A carrier gas is injected that in operation carries the atomised coating particles (10) to the surface (3a) of the object (3).

A nozzle for an atomizer includes a plate, a piezoelectric actuator, a body, and a connector. The plate defines an aperture. The actuator is configured to oscillate the plate. The body supports the plate. The connector is configured to reversibly mount the body to the atomizer in a first orientation and in a second orientation. In the first orientation, fluid exits the nozzle along a first axial direction through the aperture. In the second orientation, fluid exits the nozzle along an opposite axial direction through the aperture.

A method of controlling application of at least one material onto a substrate includes configuring a material applicator having an array plate with an applicator array. The applicator array has a plurality of micro-applicators with a first subset of micro-applicators and a second subset of micro-applicators. Each of the plurality of micro-applicators has a plurality of apertures through which fluid is ejected. The first subset of micro-applicators and the second subset of micro-applicators are individually addressable, and a liquid flows through the first subset of micro-applicators and a shaping gas, e.g., air, flows through the second subset of micro-applicators. The flow of shaping gas shapes the flow of the liquid from the first subset of micro-applicators to the substrate.

A nozzle dispenses a material, such as an adhesive, primer, paint, or other coating, through a dispensing port on to a substrate. The spray pattern provided by the nozzle defines, at least in part, an application pattern of the material on to the substrate. An air mask port integral with the nozzle or a separate nozzle expels a mask stream of pressurized gas. The mask stream projects toward the substrate to aid in limiting an application of the material beyond an application line on the substrate. The air-mask port and the dispensing port may be moved relative to the substrate and/or the application line such that the mask stream provides a barrier to the material being applied.

A switching device is provided for switching the flow of a fluid. The switching device includes a fluid conduit including a first inlet for said fluid and a first outlet, a first switching fluid conduit including a second inlet for a switching fluid, the first switching fluid conduit being in fluid connection with the fluid conduit at a first position between the first inlet and the first outlet, an exhaust conduit including a second outlet, the exhaust conduit being in fluid connection with the fluid conduit at a second position between the first inlet and the first position, and a control device. The switching device further includes a second switching fluid conduit in fluid connection with the exhaust conduit and the first switching fluid conduit. The control device controls the flow of the switching fluid into the first switching fluid conduit and/or the second switching fluid conduit.
