    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.

  • Publication number: 20100209615
    Abstract: A method and a system for applying hot melt adhesive powder onto a non-metallic surface are disclosed. The hot melt adhesive powder is sprayed out from a spray head while being charged with electrostatic charges, and then the charged hot melt adhesive powder will be attached to the whole surface of a non-metallic component by electrostatic force, or only attached to a desired area of the non-metallic component by pre-coating the desired area with conductive liquid. By spraying the hot melt adhesive in the form of powder, there is no need to heat the adhesive in advance. When the surface of the non-metallic component is 3-dimensional, the charged adhesive powder can be introduced onto the surface of the to-be-bonded component and attached to the desired surface without the omni-directional spraying operation. Excessive powder will be easily blown or brushed away and will be recycled.

  • Publication number: 20100183817
    Abstract: An electrostatic coating method in which a coating material cartridge is used. When a coating material feeding path (68, 88) is cleaned by a liquid fed from a coating material feeding unit (20), the liquid is fed from the coating material feeding unit to a storage part (13) and stored. The liquid in the storage part is then fed to a fluid chamber (83) inside a coating material cartridge (19) via a fluid circuit (10A). The liquid in the fluid chamber pushes out the electrically conductive coating material inside a coating material chamber (84) via a free piston (82), and the electrically conductive coating material is fed to a coating gun (14).
