An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

Printing apparatus includes: a printer (thin-film carrier, conveyer, and droplet discharger) printing on a thin film by discharging, while shifting thin film in first direction, droplets containing a functional component from a plurality of positions differing from each other in second direction; and a print uniformity controller (print controller and position switcher) performing the printing for a plurality of times, by using the printer and changing position and/or orientation of thin film relative to the plurality of positions.

A method of applying a coating product on a surface of a part, this method being carried out using an applicator including at least one row of nozzles, among which at least the first nozzle in the row includes a valve, the method including moving the applicator in a first direction to apply a first layer of coating product, and moving the applicator in a second direction substantially parallel to the first direction to apply a second layer of coating product adjacent to the first layer, comprising measuring at least one application distance of the first nozzle from a point in front of the first nozzle on a path of the applicator, and based on the measured application distance, opening or closing the valve.

A perforated plate is provided for an application device for the application of a coating agent, in particular a paint, a sealant, a glue or a separating agent, to a component, in particular to a motor vehicle body component. The perforated plate contains at least one through-hole for passing the coating agent through and a hole exit opening on the side of the perforated plate that is located downstream with a wetting surface that can be wetted during operation by the coating agent. The through-hole, to reduce the wetting tendency, transitions into a protruding pipe stub or has a structure that reduces the wetting tendency and/or improves the flushability, e.g., a microstructuring or a nanostructuring.

The present disclosure relates to nozzle assemblies and methods of distributing an adhesive from a nozzle. A method may include steps of: melting the adhesive at a temperature of at least 100 C.; transporting the molten adhesive to the nozzle, wherein the nozzle includes an upper nozzle assembly, a lower nozzle assembly, and at least one duct within at least the upper nozzle assembly through which the molten adhesive is transported. The lower nozzle assembly may include at least one cooling gas duct, wherein cooling gas passes through the cooling gas duct. The temperature of the cooling gas may be from 20 C. to +50 C. The nozzle may include an adhesive distribution shim, the adhesive distribution shim may include two sides, and adhesive distribution channels are arranged in both sides of the adhesive distribution shim.

An application material container has a fixed portion and a container portion. The fixed portion is configured to be fixable to a fixing member included in an application mechanism. The container portion is provided with, in upper and lower portions thereof, a hole and a hole through which an application needle passes. A side surface of the container portion has a first flange. A lower surface of the first flange is in contact with an upper surface of the fixed portion. A gap is provided between a portion lower than the first flange on the side surface of the container portion and a side surface of the fixed portion. The container portion is horizontally movable within a range of the gap.

An displacement-expansion mechanism and a liquid-coating apparatus including the same can achieve high-speed and stable control of coating of high-viscosity liquid materials. The liquid-coating apparatus, includes: (a) a nozzle hole from which a liquid material is discharged; (b) a supply flow channel that supplies the liquid material to the nozzle hole; (c) a plunger that reciprocates in contact with the liquid material inside the supply flow channel; (d) a displacement-expansion mechanism that displaces the plunger; and (e) an actuator that displaces the displacement-expansion mechanism, wherein at least either of contact parts of the displacement-expansion mechanism and the actuator has a curved surface.

A flux unit includes a flux supply device configured to eject flux to a storage tray, an ejection port configured to eject the flux, and an ejection port moving device configured to move the ejection port in the radial direction of the storage tray. By this, the flux is ejected in a wide range in the radial direction of the storage tray. Also, the storage tray is rotated by a tray rotation device. Thus, the film thickness of the flux ejected in the wide range of the storage tray is adjusted by a squeegee all at once. Thus, the time required for adjusting the film thickness of the flux can be reduced.

The disclosure concerns a perforated plate for an application device for application of a fluid to a component, preferably a motor vehicle body and/or an attachment for this. The perforated plate comprises at least four through-holes for passage of the fluid, wherein the through-holes are assigned to a nozzle row with a central region and two edge regions and are spaced apart from each other by hole spacings, wherein the at least one outermost hole spacing of the nozzle row in at least one edge region is larger than at least one hole spacing in the central region. The disclosure also comprises an application device and an application method with such a perforated plate.

The disclosure relates to a perforated plate for an application apparatus for the application of a fluid onto a component, preferably a motor vehicle bodywork and/or an add-on part therefor. The perforated plate comprises at least three through-holes for the passage of the fluid, wherein the through-holes are assigned to a row of nozzles with a central region and two edge regions, wherein the at least one outermost through-hole in at least one edge region has at least one reference opening diameter that is smaller than at least one reference opening diameter of at least one through-hole in the central region. The disclosure also relates to an application apparatus and an application method with such a perforated plate.
