摘要:
A painting target surface of a resin bumper is painted by discharging a paint mist from a spray gun toward the painting target surface with a charged conductor arranged in contact with an opposite side to the painting target surface. The paint mist is uncharged or is charged with electric charges having an opposite polarity to that of the conductor and at a potential having a lower absolute value than that of the conductor.

A sintered magnet body is held in a grounded jig exhibiting excellent electrical conductivity, a rare-earth-compound powder is charged and sprayed on the sintered magnet body to electrostatically coat the sintered magnet body with the powder, and thus apply the powder to the sintered magnet body. The sintered magnet body having the powder applied thereto is heat treated to produce a rare-earth magnet. As a result, the rare-earth-compound powder can be uniformly applied to the surface of the sintered magnet body, and the application operating can be performed extremely efficiently.

This method allows a coating product to be applied to a component (13) being moved by a conveyor (12), along which conveyor at least one spray (62.1, 62.2) is arranged. It comprises automated steps involving determining, within a fixed frame of reference (X12, Y12, Z12), the coordinates of the points (A1, B1, C1, A2, B2, C2) of one or more lines (L1, L2) of the exterior profile of the component which are distributed along the length of the component, in assigning to each spray the points of each exterior profile line that lie within its field of spraying, in identifying, from among the points assigned to each spray, the point (A1, A2; B1, B2) closest to the spray for each exterior profile line, in determining, for each spray, a line (L3, L4) to follow that passes through all the points (A1, A2, B1, B2) closest to the spray as identified in step c), and in establishing a reference path for each spray according to the points on the line (L3, L4) to follow so that the application distance of each spray is adjusted automatically and independently according to the exterior profile of the component.

摘要:
A method of stripping, prepping and coating a surface comprises first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface.

摘要:
A coating apparatus produces a spray of charged droplets and controls the spray angle of travel of the spray toward the object to be coated. Electrically charging droplets minimizes the amount of coating material required to uniformly coat a surface as compared to conventional web coating techniques such as blade coating. An inductive ring guides the spray charged droplets as they exit the nozzle of a spray device. The electrostatic repulsion between the charged droplets insures that a uniform coating of liquid formulation can be applied to a web surface.
