Corresponding to small-diameter long holes with a water jet.
■Overview of Processing Example Product Name: TOMBO No.9007-LC Long Hole Processed Gasket / Dimensions: 25W×86L×t2mm, Long Holes 11×20 (2 locations), R12.5 / This processing example uses a PTFE-based gasket material with excellent creep resistance and features two small diameter long holes in a custom shape. It was manufactured as a sealing component for piping equipment in chemical plants. The small diameter long holes were cut with high precision using water jet processing, minimizing thermal deformation. Complex shapes were achieved in a short delivery time without compromising the properties of the PTFE material. ■Product Features TOMBO No.9007-LC is a gasket that incorporates silica into PTFE to improve creep resistance at high temperatures. It is less prone to deformation compared to conventional PTFE and has excellent chemical resistance, but it cannot be used with hydrofluoric acid or strong alkalis. It is suitable for sealing areas in chemical plants where deformation or loosening due to heat is a concern.

basic information
■Processing Method A water jet is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the injection nozzle according to the processing material, it is possible to produce high-quality products in a short time. Additionally, the dimensional tolerances that were significantly affected by traditional manual processing are greatly improved, resulting in stable processing accuracy. The taper on the cutting surface caused by press processing can also be improved with water jet processing. ■Q&A Q: What applications is TOMBO No.9007-LC suitable for? A: It is suitable for seals on piping flanges and valves in chemical plants where creep deformation due to heat is a concern in high-temperature environments. Q: Is it possible to process small-diameter long holes? A: With water jet processing, small-diameter long holes of about 11×20mm can be processed with high precision. There is no thermal effect, so dimensional accuracy is stable. Q: Is it possible to accommodate prototypes or small lots? A: We can accommodate prototypes and small lots starting from one piece. Please feel free to consult us about custom shapes.
