Supports large-diameter gaskets with water jet processing.
■Overview of Processing Example Product Name: Large Diameter Gasket Dimensions: φ3060 × φ2750 × t6.4 This case study involves the processing of a large diameter gasket using D5400 glass cloth. The product is used for duct flange applications and is manufactured by combining split processing with adhesive bonding through water jet cutting. Even sizes that are difficult to handle individually can be produced while ensuring dimensional accuracy through split processing. By using a processing method that does not impart thermal effects, stable quality is achieved while maintaining material properties. ■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. There are various processing methods, including sewing, allowing for large diameter processing. It is used for high-temperature duct sealing.

basic information
■Processing Method | Water Jet Cutting Water jet cutting is a hydraulic 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.
