The disclosure concerns a printhead for the application of a coating agent to a component, in particular for painting a vehicle body component with a paint. The disclosure provides that the printhead is designed in such a way that it enables a color change during coating operation and can be rinsed with a rinsing agent during a color change in order to rinse out coating agent residues from the printhead.

Methods and systems for automatically spraying a glaze solution onto a dental prosthesis are described. The automated spray glazing system includes: a first spray gun; a controller, and a gripper configured to hold the dental prosthesis and to rotate the dental prosthesis about an axis. The controller is configured to rotate the gripper and spray a glaze solution from the first spray gun using a glazing profile based at least in part on a type of the dental prosthesis. The glazing profile is selected such that a cross-sectional thickness of a resulting-glazed material of the dental prosthesis has an average thickness range between 15 to 63 μm and a standard deviation of less than 6 μm when measured at locations in an upper half of the dental prosthesis.

A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

A feeding device for feeding coating and/or cleaning agents to a sprayer has an annular structure and includes an annular plate, a plurality of connection modules, a plurality of function modules and a plurality of inlet modules. Each connection module is removably mounted to bear against one side of the annular plate. Each function module is removably mounted on an outer face of a connection module. Each function module is fluidically coupled to the connection module onto which same is mounted. Each inlet module is removably mounted on an inlet face of a connection module. Each inlet module carries fluidic coupling elements accessible on a face of the inlet module, oriented opposite the connection module on the inlet face of which same is mounted.

A facility for applying a coating product including a set of printing nozzles, each nozzle including an outlet channel emerging in the downstream direction by a coating product discharge orifice, the facility further including a cleaning station for at least one nozzle of the set of printing nozzles, the station including at least one cleaning fluid injector in the outlet channel of the printing nozzle, through its discharge orifice.

A spray system includes a spray applicator configured to apply a fluid to a target. The spray system also includes a rotary bell cup of the spray applicator, a splash plate of the spray applicator coupled to the rotary bell cup, and a fluid tip of the spray applicator. The fluid tip is configured to output the fluid onto the rotary bell cup. The fluid tip includes a fluid tip passage extending along a longitudinal fluid tip axis of the fluid tip. The longitudinal fluid tip axis intersects with the splash plate of the spray applicator. The fluid tip also includes a fluid exit port configured to output the fluid from the fluid tip passage onto the rotary bell cup. The fluid exit port extends along a fluid exit axis disposed at an angle relative to the longitudinal fluid tip axis of the fluid tip.
