Processing example of D5800 graphite-equipped frame gasket.

Supports complex shapes with cross rubber coating processing.

■Overview of Processing Example Product Name: Frame Gasket Dimensions: R790 × R746 × 855L This processing example involves the production of a gasket in the shape of a frame, combining curves and straight lines, through cross rubber coating. It features a structure with bolt holes evenly distributed around the perimeter, suitable for sealing applications in equipment covers and large flange connections. Due to the mixture of complex R shapes and straight sections, specifications require both dimensional accuracy and hole position accuracy. It is primarily used in the fields of industrial machinery and equipment, where alignment during assembly and stable adhesion are emphasized. The cross rubber coating process maintains the material's flexibility while achieving a uniform finish even for complex shapes, ensuring high reproducibility of processing quality. ■Product Features | D5800 Duct flanges and manhole gaskets for exhaust gases, combustion gases, and hot air. Uses bio-soluble fiber cloth compliant with RCF regulations. Various processing methods, including sewing, are available, allowing for large diameter processing. Used for high-temperature duct sealing.

basic information

■Processing Method | Rubber Coating Processing Rubber coating processing is a technology that creates high-performance composite materials by adding the diverse functions of rubber to the excellent heat resistance of the base material. The rubber coating makes it easier to cut, punch, and sew glass fabric, facilitating the production of complex shapes such as gaskets and ducts. The material can be layered and shaped to the desired thickness. We can recommend the most suitable material based on the operating temperature.
