An additively manufactured (AM) object may include a body including an opening in an exterior surface thereof, the opening having a shape and a first area at the exterior surface of the body. A mask may be positioned over the opening. The mask has the shape of the opening and a second area that is larger than the first area so as to overhang the exterior surface of the body about the opening. A plurality of support ligaments couple to the mask and the exterior surface of the body at a location adjacent to the opening to support a portion of the mask. A coating can be applied to the object, and the mask removed. The final AM object includes a plurality of ligament elements extending from the exterior surface of the body and through the coating adjacent the opening, each ligament element at least partially surrounded by the coating.

The invention relates to applying a liquid to pasty hot-melt adhesive to a substrate (44), comprising a template (29), having at least one cavity (38) for the hot-melt adhesive, and also comprising an adhesive-transfer infeed (33), which is assigned to the template (29) and through which the adhesive can be introduced into the cavity (38). The special feature consists in that the apparatus (10) further comprises a transporting-fluid-supply opening (35), assigned to the template (29), and a device for displacing (13, 15), in particular pivoting, the template (29) between a first position, in which the cavity (38) is assigned to the adhesive-transfer infeed (33), and a second position, in which the cavity (38) is assigned to the transporting-fluid-supply opening (35), and therefore the adhesive, in the second position, can be discharged from the cavity (38) by a transporting fluid flowing through the transporting-fluid-supply opening (35).
摘要:
A thermal metal spraying apparatus for use with a thermal metal spraying torch for applying a metal coating to a workpiece through a torch spraying nozzle having a spraying orifice. The thermal metal spraying apparatus provides a substantially tubular shroud having a first end and a second end adaptable to concentrically receive the torch spraying nozzle. The shroud has an opening at the second end, wherein the opening is selectably alignable with the spraying orifice. A drive mechanism is connected to the shroud and is operable to translate the shroud between a first position, wherein the opening at the second end is not aligned with the spraying orifice, thereby preventing the spraying of the metal coating on the workpiece, and a second position, wherein the opening at the second end is aligned with the spraying orifice permitting the spraying of the metal coating toward the workpiece.
摘要:
A bore masking system for effectively protecting the interior surface of a bore during all phases of the painting process. The bore masking system includes a tubular shield formed from a hydrophobic sheet to protect the interior surface of the bore during the various phases of the painting process including cleaning, painting and curing. The hydrophobic sheet repels liquids such as water, chemicals and paint to ensure the structural integrity of the tubular shield during the painting phases.

A plug assembly for masking internal threads of a base component is disclosed herein. The plug assembly includes a plug member having peripheral margin portions. The peripheral margin portion is engagable with the internal threads of the base component. The plug consists of a water-soluble material and is structured and arranged to dissolve in a water based liquid.
摘要:
A masking apparatus is provided for masking a workpiece, for example a turbine blade, to protect portions thereof from the deposition of coating material thereon during selective application of a coating material to other portions of the workpiece. The masking apparatus includes an enclosure formed of a first mask half body defining a first cavity half and a second mask half body defining a second cavity half. The first mask half body and the second mask half body mate in assembly to form a workpiece cavity it which the workpiece may be enclosed.
摘要:
A foam mount of an aircraft window has a groove to receive an electro chromic window. The foam mount is painted by placing a blank in the groove to divide the foam mount into a first section designated to face the exterior of the aircraft and an opposite second section. The groove and the first section are coated with an electric conductive paint, and the second section is covered with a decorative paint. The conductive coating on the foam mount and the conductive coating of the electrodes of the electro chromic window provide an RF shielding to prevent electronic signals from personal electronic equipment from passing through the cabin and door windows of the aircraft. A mask is also provided to coat one section of the foam mount while covering the other section.
