Methods and processes are described that enable the manufacture of a superior thin-walled mold from which higher-quality, less-costly disposable gloves can be more efficiently produced. The method can include creating a glove form in a sacrificial material; electroforming an electroformed master from the glove form; removing sacrificial material from the electroformed master; creating a tertiary form from the electroformed master; forming an initial copper layering on the tertiary form; and developing the initial copper layering into a thick copper plating to create a copper mold for gloves.

An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 μm thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.
