Supports long hole drilling with water jet processing.
■Overview of Processing Example Dimensions: 150W × 712L (Thickness 2t) This example involves the production of a long gasket processed with tape using D5400 glass cloth material. It features a strip shape of 150W × 712L with six 14φ holes arranged to improve positioning during installation and enhance work efficiency. In long shapes, linear accuracy and hole pitch accuracy are crucial, so water jet processing was adopted. This method allows for processing without thermal impact, ensuring a uniform cutting surface without compromising material properties. The tape-equipped specification facilitates temporary fixing, contributing to improved workability on-site. ■Product Features (D5400) This gasket is made by applying natural rubber to glass cloth and molding it into a 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) 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 are typically associated with manual processing are significantly improved, resulting in stable processing accuracy. The taper on the cut surface from press processing can also be improved with water jet cutting.
