The invention relates to a device and a method for the metallic coating of a work piece with a mobile coating lance (20), by means of which a metal plasma jet can be generated to create the coating consisting of metal particles. According to the invention, an extraction hood (30) is provided, which at least encloses an axial section of the coating lance (20) in a ring-shaped manner, and the extraction hood (30) has a ring-shaped holding unit (50), which is configured to take up the metal particles.

A transfer and coating apparatus transfers a component from a conveyor to a coating station for application of a coating. The transfer apparatus includes a mast that can move about orthogonal axes in a horizontal plane and a mast having a carriage that can move vertically. The carriage includes a hook that swings about a horizontal axis relative to the mast for movement of the component in the horizontal direction. A sway bar extends between the hook and component to inhibit movement about a horizontal axis. The component is delivered to an upper compartment of a coating apparatus where it can be lowered in to a lower compartment containing coating material. Excess coating material is removed by an array of nozzles in the upper compartment as the component is raised from the coating material.

A pigmented pulverulent composition based on polyamide for coating substrates, including: (a) 40% to 99% by weight of at least one polyamide, (b) 1% to 30% by weight of at least one pigment, and (c) 0% to 30% by weight of at least one additive, wherein the polyamide has an inherent viscosity, as measured using an Ubbelohde tube at 20? C. on a 0.5% by weight solution in m-cresol according to standard ISO 307 but with a measuring temperature of 20? C. rather than 25? C., of more than 0.7 (g/100 g)?1, and wherein the composition has a volume-median diameter Dv50, as measured according to standard ISO 9276parts 1 to 6, of 10 to 200 ?m. A process for manufacturing the composition, the use thereof for coating ametallicsubstrate, and an object comprising a metallic substrate coated with a coating obtained with the pigmented pulverulent composition based on polyamide.

The present application discloses an automatic powder cleaning process and device for wheel bolt holes. The device comprises a vacuum pump, a steady pressure tank, a powder cleaning robot, a powder cleaning gun, a control system and accessories. According to the process and the device, shielded protection is canceled, and powder at the mounting part of a wheel bolt hole is automatically cleaned, so that the process and the device are suitable for various wheel products, and the labor and the labor cost are reduced; the problems that a lot of different types of protective plugs needed for wheels are inconvenient to customize and store and high in cost are avoided.

An aspect of the present disclosure provides a system for aerosol jet printing an aerosolized particle source configured to selectively provide aerosolized particles, a nozzle configured to deposit aerosolized particles on a substrate, an actuator configured to generate acoustic energy for migrating the particles, and a generator configured to selectively energize the actuator. The nozzle includes a proximal inlet configured for passage of aerosolized particles, a column configured to focus the aerosolized particles when vibrated by an actuator, and a distal opening configured for deposition of the particles on a substrate.

Provided is an operation method for a coating exhaust treatment system that includes a filter configured to filter discharged air discharged from a coating chamber in which a coating object is spray-coated and collect overspray coating material included in the discharged air, and a powder dispersal means configured to disperse powder for forming a filter covering layer in the discharged air and form a filter covering layer made of a layer of the accumulated powder on a surface on the filter as the discharged air passes through the filter, the method including, when the number of repetitions of a first operation reaches a set number while the first operation and a second operation are being repeatedly carried out alternatingly, discarding coating material-containing powder and supplying fresh powder to a first supply tank, and when the number of repetitions of the second operation reaches the set number, discarding the coating material-containing powder and supplying the fresh powder to the second supply tank.

A method and system for feeding a lubricating or releasing agent from a dosing station to one or more pressing tools arranged in a pressing chamber of a tablet press. The tablet press is configured with a feed pipe for feeding the lubricating or release agent from the dosing station to the one or more pressing tools of a pressing chamber of the tablet press and the feed pipe is configured with a shut-off valve disposed in-line with the feed pip for controlling the flow of the lubricating or release agent to the pressing chamber. The method comprises the steps of: producing a negative pressure with respect to the surroundings of the pressing chamber of the tablet press, measuring a pressure in one of the feed pipe and the pressing chamber, and issuing a signal indicative of the measured pressure and issuing an enable signal to open a valve in response to the pressure signal.

Provided is a flocking processing device which includes: a processing unit, and injector is installed around the processing object to inject the fibers; a dust collection unit having an inlet; a supply unit; a separation unit scattering the fibers while passing through the filter installed on an outer surface of a separation tank; and a distribution unit in which distribution members is installed below partitioned distribution pipes in the lower portion of the collection tank. Air is input into the respective distribution members to evenly supply the fibers to the injectors.
