Compatible with R5 U-shaped cutting using water jet processing.
Processing Case Overview Product Name: Ring Gasket (R5 U-shaped Cut) Dimensions: φ460×φ361 (t6.4) This processing case involves a large-diameter ring gasket used in wind power-related equipment. Due to its special shape, which includes R5 U-shaped notches and jigsaw cuts, water jet processing was adopted instead of mold processing. By using non-contact cutting, stable processing accuracy is ensured even for the thick D5400, leading to improved fit during assembly and enhanced workability. Product Features (D5400) This gasket is made by applying natural rubber to glass cloth and molding it into the specified shape. It has excellent thermal insulation properties and is environmentally friendly as it is non-asbestos. Various processing methods, including sewing, are available, allowing for large-diameter processing. It is used for high-temperature duct sealing.

basic information
Processing Method (Water Jet Cutting) 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, high-quality products can be produced 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 from press processing can also be improved with water jet cutting.

Q&A Q: Can you accommodate special R shapes? A: Yes, it is possible. Since we process based on drawing data, it is easier to ensure repeatability and precision. Q: Can you process large diameters? A: Yes, it is possible. We can handle large diameter sizes with our large equipment. Q: Is it possible to support prototyping? A: Yes, it is possible. Since no molds are required, it is suitable for short lead-time prototypes. Daiko's Capability At Daiko, we organize the application conditions (temperature, fluid, pressure) from the material selection stage and propose the optimal sheet material and processing method. We can accommodate difficult shapes such as large diameters, split shapes, and special R processing, providing consistent support from prototyping and small lots to mass production. Even without drawing data, we can trace shapes and confirm dimensions from actual items, ensuring stable quality in production.
