The present invention discloses a shielding jig which mainly comprises an adjustment unit, a positioning unit and a sealing unit. The adjustment unit is configured and engaged between the positioning unit and the sealing unit. Therefore, a first actuation surface of the adjustment unit matches with a second actuation surface of the sealing unit, resulting in expansion of the sealing unit. This expansion makes the shielding jig be able to shade and seal any workpiece.

Installers for elongate foam masking tape have an elongate body that has a spine opposite a fore edge, which are separated from one another by opposing exterior surfaces, and has a material that prevents adhesion of an adhesive on each of the opposing exterior surfaces at a position adjacent to the fore edge and extending the length of the elongate body. The installers are used to insert tubular foam masking tape in the gap between body panels of an automobile vehicle, for example, and to adhere the tubular foaming masking tape to the rear surface of the body panels prior to application of paint thereto. Methods of installing tubular foam masking tape between body panels using the installer are disclosed as well.

Paint mask assemblies are described herein in various embodiments. A paint mask assembly includes a window portion having a removable mask affixed thereto. The paint mask assembly can be affixed over a mark on a surface so that the mark is visible through the window portion of the paint mask assembly. When the paint mask assembly is painted, the paint is applied over the removable mask, but the window portion remains unpainted. When the removable mask is removed, the mark remains visible through the window portion of the paint mask assembly.

The present disclosure relates to masks, mask assemblies, and methods for manufacturing masks. The mask is configured to be tensioned and soldered on a support frame. The mask is an electroformed mask. The mask includes an evaporation area, a non-evaporation area, and a soldering area used to be soldered to the support frame. At least the soldering area is doped with magnetic metal ions, thereby improving soldering performance of the soldering area.

A method of manufacturing a shroud segment for gas turbine engine includes providing an insert having a plurality of pins that extend into a platform cavity portion of a mold cavity. A powder injection molding feedstock is injected. When the green part is disengaged from the mold, each elongated feature is slid out of the green part to define a respective elongated cooling passage in the platform. The method may include, after debinding and sintering, projecting a coating material while defining an obstruction between source of coating material and the open end of each elongated feature with a shoulder of the element to prevent the coating material from reaching the open end, followed by machining to remove at least a part of the shoulder.

A template (100) for controlling application of material (620) around a protuberance (610) is disclosed. The protuberance (610) extends from a workpiece (600) and has a base (612). The template (100) comprises a first portion (110) and a second portion (130), removably attached to the first portion (110). The first portion (110) comprises a first inner peripheral edge (111) that at least partially defines a positioning opening (115) and that is geometrically complementary to at least a portion of the base (612) of the protuberance (610). The first portion (110) also comprises a first-portion environment-facing surface (114). The second portion (130) comprises a second-portion environment-facing surface (136), which partially overlaps with and is removably attached to the first-portion workpiece-facing surface (114), forming an interface (120) between the first-portion workpiece-facing surface (114) and the second-portion environment-facing surface (136).

A slurry spraying mask includes a holding portion and a mask portion. The holding portion includes a holding portion opening. The mask portion includes a first layer and a second layer. The first layer includes a first tapered structure, the second layer includes a second tapered structure. The first tapered structure and the second tapered structure are arranged coaxially. A gap exists between the first layer and the second layer. The apex of the first tapered structure includes a first aperture, the apex of the second tapered structure includes a second aperture, and the second aperture is overlapped with the first aperture. The apex of the second tapered structure passes through the holding portion opening such that the mask portion is localized to the holding portion.
