Support for complex inner diameter shapes with plotter processing.
■Overview of Processing Example Product Name: D4000 Manufactured Flange Gasket (with Partition Shape) / Dimensions: Outer Diameter 400φ × Inner Diameter 270φ × Thickness 2t, Bolt Holes 25φ × 12 Locations (P355), with Partition Ribs in the Inner Diameter Section (R10-4) / This processing example features a special flange gasket with a partition shape in the inner diameter section. In addition to the standard annular shape, a partition rib that divides the inner diameter into two parts is machined as a single piece. Thanks to plotter processing, such complex cut-out shapes can be handled with high precision without the need for molds. ■Product Features D4000 is a joint sheet primarily composed of expanded graphite. It has excellent heat resistance and chemical resistance, making it suitable for high-temperature steam and various chemical substances. Its flexibility and superior conformability to flange surfaces allow it to be used for sealing in a wide range of industrial piping and valves.

basic information
■Processing Method The plotter (with router function) processing machine can handle a wide range of materials such as rubber, resin, and sheets, allowing for cutting as well as machining with a router. By combining cutting and machining, it becomes possible to create more complex shapes and three-dimensional processing. Materials that are thick or hard, which are difficult to process with a standalone plotter, can be processed using the router function. ■Q&A Q: What is the purpose of the partition shape in the inner diameter section? A: It is provided to control the flow of fluids and to partition the interior of the piping. Shape design can be customized according to the application. Q: Is the strength of the partition section sufficient? A: D4000 is made from a material that combines flexibility and strength, so if designed with an appropriate thickness, there are no practical issues. Q: Can partitions of other shapes be processed? A: Yes, since plotter processing is data-driven, it can flexibly accommodate various partition shapes and hole arrangements.
