Custom Belt Fabrication of a Transport Belt for Dental X-ray Equipment

A manufacturer of dental x-ray processing equipment was experiencing a quality issue with a carrier belt in one of their systems. The problem arose from the belting system they were using to transport the x-ray film. The belt which is used to carry the finished film to viewing was made from woven polyester fabric with a silicone cover. The problem stemmed from the polyester fabric which was showing through the silicone cover distorting the x-ray image.

To mitigate this issue, we developed a belting system made from a clear Ultem substrate that was also coated with silicone. The transparent nature of the substrate prevented x-ray image distortion. This further enhanced the knitted endless and spin casting manufacturing process that was utilized. This innovative solution delivers a seamless belt that offers higher strength and longer service life.

The finished belt featured dimensions of 171 mm in circumference, a width of 30 mm, and a thickness of 1 mm. This transport belt project was completed to tightest tolerances of +0/-0.01 mm on length and delivered to the client in 6 weeks.

At Belt Corp, our ability to manufacture innovative, specialty belting solutions makes us leaders in the industry. In this project we provided a unique solution to solve the client’s image quality problem and delivered a trouble free conveying solution.

  • Company using a woven polyester belt with a silicone cover to process dental x-ray film.
  • Client needed to improve quality of the x-ray image since the fabric tends to show through the silicone.
  • Belt Corporation of America’s solution: a clear spin cast Ultem substrate with the same silicone surface cover.
  • Still being tested for life cycles.
