basic information
■Product Features (No.6500) No.6500 is a general-purpose joint sheet primarily made 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 as a seal in piping and equipment across various industries and complies with JIS standards for water supply. However, caution is required for conditions exceeding 100°C. ■Processing Method (Water Jet Cutting) Water jet cutting is a method that uses high-pressure water to cut materials. It processes by spraying high-pressure water. The injection nozzle can be changed according to the processing material, allowing for the production of high-quality products in a short time. Additionally, the dimensional tolerances achieved through traditional manual processing are significantly improved, resulting in stable processing accuracy. The taper of cut surfaces from press processing can also be improved with water jet cutting.
