Abstract:
A method to coat a substrate for the formation of coatings having a desired surface morphology is provided, wherein the roughness and the total surface area of the coating can be varied during the coating process. The method of the present invention comprises the steps of generating droplets from a coating composition, transporting the droplets to the substrate and depositing the droplets on the substrate.
Abstract:
An atomizing device, comprising a fine liquid tube, a holder to permanently fix the tube proximate to its exit end and an optional cap to homogeneously and repeatably disintegrate small liquid amounts is disclosed. A manufacturing method for reproducibly machining the atomizer assembly of the present invention is provided.
Abstract:
The invention provides a precision spraying device having an improved atomizing end for reproducibly forming droplets from small amounts of liquid with improved operational stability and spray pattern quality as well as a method of manufacturing. The invention further provides a method for reproducibly coating substrates using the spraying device of the present invention.
Abstract:
An apparatus and method is provided to allow higher volume production of medical devices and to minimize coating defects resulting from manual handling of medical devices by supporting multiple medical devices at the same time and performing one or more process steps automatically.
Abstract:
This invention relates to a multi-purpose holding device to handle, support and rotate one or more hollow cylindrical objects. The holding device consists of a rigid frame and support members for precise alignment and rotation of one or more objects within the frame structure. A method is also provided to reproducibly support, rotate and inspect the hollow cylindrical objects.
Abstract:
A holding device and method is provided for efficiently applying a coating on the exterior surface of a tubular hollow body, while preventing coating application on the interior surface and coating defects. The holding device of the present invention comprises at least two structures contacting the inner surface of the tubular hollow body and extending to a portion where the structures are connected and rotary motion is induced to rotate the tubular hollow body. The structures are arranged and shaped so that an inner hollow section is formed in which excess coating material can accumulate.
