Abstract: A powder hopper is provided with a low turbulence zone for supplying powder to a spray gun. The low turbulence zone is defined by a baffle inside the hopper with the low turbulence zone being within a volume of the baffle, and an annular zone between the baffle and the hopper is used to bulk feed powder into the hopper. The low turbulence zone may alternatively be in the annular zone with powder added to the volume of the baffle. One preferred application for this hopper is in connection with the use of fine powder coating materials to coat the interior of small diameter cans.

Abstract: Wear components of a powder coating system are provided with a coded visual element in one aspect of the invention. The coded visual element can provide an indication of the manufacturer or a characteristic of the part. In molded parts, the coded visual element can be implemented as a different color overmolded part wherein a material of one color is overmolded on a base material of another color. The overmolded material can be elastomeric and formed with integral exterior rings to provide a friction fit for the wear component in, for example, a venturi pump or a spray gun while eliminating the need for separate O- rings and the need to machine or form grooves in the exterior of the parts to receive the O-rings. Similarly, integral flanges can be formed to eliminate the need for separate snap rings and grooves to accept the snap rings. Color coding of the overmolded material can also be implemented in a way to provide an indication of wear. Alternatively, the part can be constructed as a layered structure of two or more materials to provide an indication of wear with or without a visual coding element Another aspect of the invention is the idea of forming the replacement part as a single piece part such as a molded part. This type of part can be formed to incorporate integrally formed resilient rings and/or integrally formed flanges on the exterior of the part to take the place of O-rings and snap rings.

Abstract: A spray applicator for particulate material includes a unitary powder passageway sized to be particularly useful with dense phase material flow. An external electrode assembly is provided that is keyed to an air cap that is used to provide atomizing and pattern shaping air to the dense phase material that exits the powder passageway. In this manner a nozzle is not required. A manual and automatic version of the applicator are provided, including a pattern shaping trigger that can be used by the operator to dynamically adjust the spray pattern. An automatic gun version has the multiplier located at a mounting location to reduce bending moments of the elongated gun.

The cell also contains at least one electrostatic charger for charging the suspended resin particles and at least one apparatus for accelerating the carrier flow and the suspended particles. Finally, the cell includes at least one flow-modifying apparatus for modifying the resin particle outflow, producing a uniform delivery of the particles across the substrate.

Abstract: A plurality of unconventional negative tribo-charging materials are described for use as the powder contact surfaces in tribocharging and corona powder spray guns, gun compounds, and powder delivery system components. The invention also provides a short barrel tribo-charging powder spray gun having an interchangeable powder contact insert and nozzle, with turbulence inducing air jets. The invention further provides novel tribocharging and corona gun designs. Improved powder coating systems are made possible wherein, for example, negative tribo guns can be utilized with negative corona guns to coat different parts of the same workpiece in a powder coating system and to realize a repair coating process. Also proived is an inside-out configuration in which pressurized air directs powder coating material outward towards a charging surface. Additional configurations provide air jet induced tribocharging and conventional tribocharging portions combined in a single gun.
