Achieving high-precision opening shapes with water jet processing.
■Overview of Processing Example Product Name: Fluororubber Gasket with Opening / Dimensions: Rectangular Sheet Shape, with Slit Opening / This processing example features a gasket made from fluororubber sheet with a slit opening. It is used in environments where heat resistance and chemical resistance are required, such as chemical plants and semiconductor manufacturing equipment. By adopting water jet processing, we can cut narrow slit openings with high precision without compromising the excellent properties of fluororubber. There is no deformation or material degradation due to thermal effects, ensuring the quality of the sealing surface. ■Product Features Fluororubber (FKM) is a material that ranks at the top of synthetic rubbers. It boasts outstanding performance in heat resistance (up to 250°C), oil resistance, and chemical resistance. It is essential as a critical component in chemical plants and semiconductor manufacturing equipment due to its stable performance even in harsh environments, but attention must be paid to its cold resistance and price.

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 cut surface from press processing can also be improved with water jet processing. ■Q&A Q: What is the temperature range for using fluorine rubber gaskets? A: Fluorine rubber can be used in a range of approximately -20°C to 250°C. It exhibits stable sealing performance even in high-temperature environments. Q: What are the advantages of water jet processing? A: Since it does not generate heat, there is no alteration of the material, and complex opening shapes can be processed with high precision. There are also fewer burrs, resulting in a good finish. Q: What is the dimensional accuracy of the openings? A: Water jet processing allows for high-precision dimensional control of approximately ±0.1mm.
