Abstract: A masking device for placement over an end of a work piece includes a head portion, a collar portion, and at least one pull tab. The head portion includes a closed end and an interior cavity defined in the head portion. The collar portion is coupled to the head portion opposite the closed end of the head portion. The collar portion includes a radially inner surface defining an opening. The opening is in fluid communication with the interior cavity of the head portion. The opening is narrower than the interior cavity of the head portion. The collar portion further includes a radially outer surface. The at least one pull tab is coupled to the radially outer surface of the collar portion.

Abstract: A masking tape may be used for covering a masking area. The masking tape includes a plurality of masking devices coupled together. Each masking device includes a perimeter and an adhesive layer. Each masking device is coupled to at least two laterally adjacent masking devices at given connection points along the perimeter. Each connection point is weak relative to the masking devices. The adhesive layer couples each masking device to a lower adjacent masking device.

Abstract: A masking device for covering a masking area includes a first member having a first tab portion and a first base portion. The masking device also includes a second member having a second tab portion and a second base portion. A pull tab of the masking device includes the first tab portion coupled to the second tab portion. The masking device further includes a third member having a member connection surface and a masking connection surface. The member connection surface is opposite the masking connection surface. A base of the masking device includes the first base portion, the second base portion, and the third member. A first adhesive couples the member connection surface of the third member to the first base portion and to the second base portion. The masking connection surface of the third member is made to removably attach to the masking area.

Abstract: A dual washer pull plug for masking a mechanical part. The dual washer pull plug includes a first centering component and a second centering component. A first masking flange is located at a first end of the first centering component and the first centering component is configured to center the first masking flange relative to an aperture of a mechanical part on a first side of the mechanical part. A second masking flange is located at a first end of the second centering component and the second centering component is configured to center the second masking flange relative to the aperture of the mechanical part on a second side of the mechanical part.

Abstract: The present invention is an optimized DWP for minimizing coating error that has two centering components which center the DWP inside a threaded or non-threaded opening effectively masking the threads and/or opening during the coating process.

Abstract: Electrically-conductive plastic hangers for supporting a workpiece during an electrostatic coating, plating, treating or other processing operation are described herein. In embodiments, the hangers have a one-piece hanger body made of an electrically-conductive plastic material, a connector portion configured to hang the hanger from a rack or other support and a further connector portion configured to hang a workpiece directly from the hanger. The further connector portion is provided in the form of a closure to seal off a part opening.

Abstract: An umbrella valve includes an elastic cap, and an elastic stem formed integrally with the cap, having a center hollow portion, having an enlarged hollow portion proximate the cap, and having a bottom. The valve has a needle having an enlarged head at a proximal end thereof for being snugly secured in the enlarged hollow portion of the stem, having a lower lateral hole in a distal portion, having an upper lateral hole proximate the bottom of the stem, and having a lengthwise center passageway connecting the upper and lower lateral holes. A method includes providing a needle for being snugly secured in one of a plurality of elastic caps, the needle having a lengthwise center passageway connecting upper and lower lateral holes. The method includes selecting a cap from among the plurality of elastic caps by determining opening pressure factors.

Abstract: A high temperature resistant masking device (10) comprising a substrate having a top surface (26) and a bottom surface (28) with an adhesive applied to the bottom surface (28) of the substrate for removable attachment to a masking surface. The masking device (10) includes a pull tab (12) extending upwardly from the device's center portion for facilitating easy placement and removal of the masking device (10) from the masking surface. The masking devices (10) are die-cut into various shapes and sizes, and placed on rolls of release liner so that they may be readily applied to parts requiring masking during a painting or coating process.

Abstract: The invention disclosed and claimed is an improved plug with an internal anchor. The plug has particular utility in masking openings in parts to be coated. Generally, the plug comprises a compressible, resilient plug body and a compression mechanism. The compression mechanism compresses the plug body between an internal plug anchor and an opposed plug compression surface. The compressive force causes the plug circumference to increase forming a tight seal between the plug and walls forming the opening. The internal anchor design and absence of any axial opening through the entire plug body prevent fluids and other coating materials from passing through the internal plug body and into the interior of the part to be coated thereby avoiding costly damage to the part.
