Definitions

  • the present invention relates to masking devices, and more particularly, to high temperature resistant masking devices having target markings applied thereon to facilitate placement of the masking devices on precision masking areas.
  • the painting or coating of parts may involve liquid coating, powder coating, plating or electroplating.
  • the coating may be applied by a variety of methods including brushing, rolling, spraying, dipping, flow-coating, electro-static coating, and submersion in deposition tanks.
  • the liquid, powder or plating material may be applied to wood, fiberglass or metal surfaces in order to protect and strengthen those surfaces.
  • the coating protects the surface of a part by preventing electrical leakage, oxidation, corrosion and decay.
  • Once the coating is applied it is often cured at temperatures between 200-600° Fahrenheit (93 - 316°C) to harden and cross-link the coating on the surface. After the curing process is complete, the cured coating forms a very strong protective layer on the surface that is highly resistant to scratching and chipping.
  • a protective coating is applied to certain areas of a surface but not to other areas of the surface.
  • the areas where the coating is not to be applied must be covered or masked off.
  • a paper or polyester film element in the form of masking tape is applied to the surface areas to be masked.
  • the masking tape generally has an adhesive on one side so that it may be affixed to the masking surface. Once the painting or coating process has been completed, the masking tape is removed from the masked surface.
  • the masking devices must often withstand high curing temperatures of approximately 200-600° Fahrenheit (93 - 316°C).
  • many masking jobs require precision placement of the masking devices on certain types of components or parts where precision placement of the masking device is critical. Typically, these components include electronic, aerospace or medical devices with very small masking tolerances.
  • the present invention provides masking devices for masking certain areas of a surface during liquid coating, powder coating, plating or electroplating.
  • the masking devices are preferably die-cut from sheet material into substrates, an adhesive is applied to the bottom surface of the substrates, markings are applied to the top surface of the substrates, and the substrates are affixed to a release liner. The masking devices are then removed from the release liner and applied to a masking surface. The markings assist in properly aligning the masking devices on the masking areas.
  • the masking devices comprise a substrate having a top surface and a bottom surface, with an adhesive applied to the bottom surface.
  • a plurality of target markings are applied to the top surface of the substrate to facilitate accurate placement and precision alignment of the masking devices on a masking surface.
  • the substrate is preferably transparent with the target markings either embossed into the top surface of the substrate or printed on the top surface of the substrate. Since the substrate is transparent, it is easy for a person to look through the substrate at the precision masking area to line up the target markings embossed or printed on the top surface of the substrate with the masking area.
  • the masking devices are transparent with target markings applied to its top surface for use in precision placement on the masking area.
  • the method of making the masking devices involves die-cutting a sheet of flexible transparent material into desired substrate shapes, applying adhesive to the bottom surface of the die-cut substrates, applying a plurality of target markings on the top surface of the substrates, and applying the marked substrates to a release liner for use in masking surface areas of parts that are to be painted or coated.
  • the present invention provides masking devices that are used for masking off areas of a surface during liquid coating, powder coating, plating or electroplating.
  • the masking devices are die-cut into various shapes and sizes, and placed on rolls of release liner so that they may be readily used for masking.
  • the masking devices are removed from the release liner and applied to the surface areas to be masked.
  • Fig. 1 shows a first embodiment of a masking device 10 having target markings 16 and 18 applied to device 10.
  • the device 10 is used for masking surfaces of a part that require precision placement of the masking device on areas having very small masking tolerances.
  • the masking device 10 preferably consists of a polyester film substrate 15 having a top surface 12 and a bottom surface 14. Adhesive is applied to the bottom surface 14 so that the masking device may be affixed to the masking area.
  • the masking device 10 can be of any shape and size, the circular shape shown in the drawings is only one example.
  • the masking device 10 is preferably made of a thin flexible transparent material such as vinyl, polyester, mylar, kapton, etc.
  • the target markings 16 and 18 are shown as concentric circles in Fig. 1, but may be of any necessary pattern or shape to accommodate the masking task.
  • Fig. 2 shows an enlarged side view of the masking device 10 along line 2-2 of Fig. 1.
  • the target markings 16 and 18 are embossed on the top surface 12 of masking device 10.
  • the markings 16 and 18 are used for assisting in accurate placement of the masking device 10 on a masking area having very small tolerances. In other words, the markings 16 and 18 are used to align the masking device on the masking area.
  • the masking device 10 is preferably made of a high temperature resistant polyester substrate 15 having a top surface 12 and a bottom surface 14.
  • a silicon adhesive (not shown) is preferably applied to the bottom surface 14 so that the masking device 10 may be removably applied to a surface to be masked.
  • the masking device 10 be transparent so that the user may see through the masking device to properly place the masking device on the surface area to be masked.
  • the transparency of the masking device 10 and the embossed markings 16 and 18 allow the masking device to be used on parts having very small masking tolerances.
  • the embossed markings 16 and 18 are pressed into the top surface of the substrate with a metal press or the like to create the creases 16 and 18 in the substrate as shown in Fig. 2.
  • the masking device 10 is preferably circular in shape with embossed concentric circles 16 and 18 acting as target markers. However, it is possible for the masking device 10 to be die-cut into a variety of shapes and sizes with variously configured target markers. Also, the markings can comprise any necessary pattern or shape required by the masking task.
  • Fig. 3 shows a plurality of masking devices 10 applied to a release liner 30.
  • the release liner 30 has a coating on its top surface 32 that allows the masking devices 10 to be easily removed from the release liner for attachment to the masking area of a part that is to be painted or coated.
  • the release liner provides an easy way to package the masking devices for sale and use.
  • the masking devices 10 are die-cut from sheets of polyester film material to form substrates of various shapes and sizes. Adhesive is applied to the bottom surface of the die-cut substrates and target markings are embossed on the top surface of the substrates. The embossed substrates are then placed on the release liner 30 and rolled up into rolls to be used by various industries that require precision masking devices for various powder or liquid coating processes.
