Supports complex shapes with water jet processing.
■Overview of Processing Example Product Name: Truck Oval Gasket / Dimensions: 180W × 270L × 0.8t, Bolt Holes φ9 × 10 holes / This processing example features a truck oval-shaped gasket made using No. 6500 joint sheet. The rounded corners of the truck shape help to alleviate stress concentration and enhance sealing performance. The outer and inner perimeters of the oval, along with 10 bolt holes, are cut with high precision using water jet processing. This method does not require a mold, making it suitable for prototyping and small lot production. ■Product Features No. 6500 is a general-purpose joint sheet primarily composed of non-asbestos fibers and heat-resistant, oil-resistant rubber (NBR). It offers excellent economic efficiency and is compatible with a wide range of fluids, including water, oil, and air. It is commonly used for sealing in piping and equipment across various industries and complies with JIS standards for water supply, although care should be taken under conditions exceeding 100°C.

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 are the advantages of a truck elliptical shape? A: By rounding the corners of the oval shape, stress concentration is prevented, resulting in stable sealing performance due to uniform tightening. Q: What is the temperature range for using No. 6500? A: A continuous use temperature of below 100°C is recommended. It is suitable for sealing general fluids such as water, oil, and air. Q: What is the positional accuracy of the bolt holes? A: Water jet processing achieves a high precision hole position of approximately ±0.1mm.
