Supports large diameter and multiple holes with water jet processing.
Processing Case Overview Product Name: D5400 Ring Gasket Dimensions: 10t φ580×φ450 P520 φ15-12 This is a large-diameter ring gasket with a thickness of 10mm made from D5400 material. It has an outer diameter of φ580 and an inner diameter of φ450, with 12 holes processed using P520. By adopting water jet processing for this thick plate with multiple holes, we minimized thermal effects, achieving stable dimensional accuracy and uniform cutting surfaces. This is a processing example for high-temperature duct applications. Product Features (D5400) This gasket is made by applying natural rubber to glass cloth and shaping it into the required form. 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 seals.

basic information
Processing Method (Water Jet Cutting) A water jet 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.
