Processing example of a three-sheet gasket with cutouts.
Supports complex shapes with water jet cutting.
■Overview of Processing Example Product Name: Gasket with Cutouts / Dimensions: Outer Diameter 220φ × Inner Diameter 190φ × P206, Thickness 7φ, Cutouts at 2 Locations / This processing example features a ring-shaped gasket made from three-sheet material processed with a water jet. Cutout shapes are provided on the outer circumference to facilitate positioning during assembly with piping and casings. Bolt holes are also processed simultaneously to accommodate attachment to flanges. The water jet processing achieves high-precision cutting surfaces even for complex shapes. ■Product Features Three-sheet (3F sheet) is a sheet material with excellent chemical resistance, primarily composed of PTFE. It is resistant to a wide range of chemicals, including acids, alkalis, and solvents, and has low leaching of impurities, making it widely used as sealing material in chemical plants and the food and pharmaceutical sectors. It is flexible and has good compatibility with flange surfaces.
basic information
■Processing Method Water jet cutting 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, high-quality products can be produced in a short time. Additionally, the dimensional tolerances that are significantly improved compared to traditional manual processing result in stable processing accuracy. The taper of the cutting surface from press processing can also be improved with water jet processing. ■Q&A Q: What is the purpose of the cut shape? A: It is to facilitate positioning during incorporation into piping or casing and to improve the efficiency of the installation work. Q: What types of fluids can the three-seat be used with? A: It can accommodate a wide range of chemicals, including acids, alkalis, and solvents. However, it cannot be used with molten alkali metals or fluorine gas. Q: Is it possible to produce in small lots? A: Yes, since water jet processing does not require molds, we can flexibly accommodate prototypes from a single piece and small lot production.
