D5800 Processing Example of Graphite-Added Gasket
Laser processing for electric furnace flanges.
■Overview of Processing Example Dimensions: φ234 × φ165 P190 This case is a processing example of the D5800 graphite-filled gasket used in the flange part of electric furnace equipment. It features a ring shape with six φ14 mounting holes, requiring assembly precision. By adopting laser processing, dimensional reproducibility of the inner and outer diameters and hole pitch is ensured, contributing to stable construction on-site. ■Product Features (D5800) 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 (Laser Processing) This is a machine tool developed for applications that perform machining impossible with conventional cutting tools and devices by cutting and slicing metals and resins using laser light. Since the processing is done without contact, the material does not deform due to stress or pressure during processing. By linking with image processing software and directly transferring data to the processing machine, the need for creating molds or patterns, which was previously necessary, has been eliminated, allowing for a variety of processing options.
