Abstract:
An apparatus for controlling a flow and application of a material onto a three-dimensional target having two or more treatment blocks thereon, wherein the apparatus is suitable for electrically charging and spraying a polymer-based material in an electric field, the apparatus comprising:one or more pressurized cylinders each containing one or more components of the polymer-based material; a first spray unit which receives the one or more components of the polymer-based material under pressure from a respective one of the one or more pressurized cylinders and provides an electrical charge to the polymer-based material; a voltage application means for applying a voltage to each of the two or more treatment blocks; and an electric field establishing means for applying an electric field between the spray unit and the three-dimensional target, wherein the first spray unit sprays the polymer-based material toward the three-dimensional target so as to coat the polymer-based material onto each of the two or more treatment blocks to a desired thickness.
