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.

The disclosure provides a fully new method for molten metal coating treatment coating treatment, as a method for treating surfaces of a metal strip by molten metal coating, by which inherent issues in conventional immersion coatings and spray coatings are avoided. In the disclosed method for molten metal coating treatment, a surface of a metal strip is coated by discharging a droplet of a molten metal toward the surface of the metal strip, using a nozzle system configured to discharge the droplet of the molten metal from a nozzle due to an action of the Lorentz force generated on the molten metal by sending an electric current to the molten metal in a chamber, the chamber being applied with magnetic flux in a given direction, while the electric current sent in a direction perpendicular to the given direction.

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.

Method of designing and manufacturing a distributor bar for use in a production line comprising a mixing head for providing a viscous foamable liquid mixture, a laminator with a predefined speed of at least 20 m/min, the distributor bar having a central inlet fluidly connected to a number of outlets via a main channel. The method comprises: choosing (3001) a geometry for the distributor bar and defining a set of geometrical parameters; assigning (3002) values to said parameters; creating (3003) a virtual model; simulating (3005) flow in said model by performing a Computational Fluid Dynamics simulation (CFD), taking into account (3004) a non-Newtonian shear thinning model; e) evaluating the simulated flow; building (2007) a physical distributor bar. A distributor bar, a production line, and a computer program product.

An apparatus for dispensing a flowable material is disclosed. The apparatus comprises a rotary actuator, a reservoir, containing a hydraulic fluid, a piston, movable inside the reservoir, a linear actuator, coupled to the piston, a gear train, coupling the rotary actuator with the linear actuator, and a flowable-material dispenser, hydraulically coupled with the reservoir.

A fluid dispenser, comprising a dispenser faceplate having at least one ejection port and a dispenser guard. The dispenser guard has at least one opening configured to allow fluid exiting from the ejection port to flow through and at least one drainage structure. The dispenser guard is spaced from the ejection port with a gap small enough to attract the fluid accumulated around the ejection port to flow into the drainage structure.

A dispensing unit for an adhesive or other viscous liquid includes one or more dispensing nozzles for delivery of the adhesive to a desired surface. The dispensing nozzles each include one or more dispensing ports that are in fluid communication with a nozzle body recess defined through a nozzle body of the dispensing nozzle. Adhesive that is supplied to the nozzle body recess may be thrown laterally from the dispensing nozzle via the dispensing ports. Each of the dispensing ports may be positioned between a pair of projections. The projections protect the dispensing port from breaking due to contact with the surface on which the adhesive is applied or contact with another exterior object.

A system and method for controlling a needle motion of a material applicator are disclosed. The system includes an actuator assembly that contains a piezoelectric device, where the actuator assembly is connected to a needle and translates the needle along a vertical direction, and a sensor assembly that includes an emitter for emitting light, where a portion of the actuator assembly occludes a portion of the light. The sensor assembly also includes a receiver for receiving a non-occluded portion of the light and a sensor holder that secures the emitter and the receiver. The system further includes a controller in electrical communication with the piezoelectric device, emitter, and receiver, where the controller adjusts operation of the actuator assembly based on feedback received from the receiver.

The disclosure relates to an application device for applying an application medium onto a component, preferably for application of a coating onto a motor vehicle body component. The application device includes a print head for preferably serial and/or permanent application of the application medium, wherein the print head has: a nozzle plate, at least one nozzle in the nozzle plate in order to discharge the application medium, at least one valve element, which is movable relative to the nozzle plate, for control of the application medium discharge through the at least one nozzle, wherein the at least one movable valve element closes the at least one nozzle in a closing position and releases it in an opening position, and at least one drive for moving the at least one valve element. The application device is characterised in particular in that it includes at least one temperature control apparatus for reducing heating of the at least one drive during application of the application medium.
