Processing example of D5800RCF high-temperature duct gasket.
Flange shape adaptation through laser processing.
Overview of Processing Example Product Name: Flange Gasket for High-Temperature Ducts Dimensions: Equivalent to JIS 10K-80A (Thickness 4mm) This example involves the processing of a gasket for duct flanges used in high-temperature exhaust equipment. Dimensional accuracy and positional reproducibility during installation were required for the circular shape, which includes bolt holes. By adopting laser processing without molds for products related to piping and equipment, we enable shape modifications and small lot production while ensuring stable processing quality. Product Features (D5800RCF) Exhaust gases, combustion gases, hot air, etc., for duct flanges and manhole gaskets. Uses biocompatible, biodegradable fiber cloth that complies with RCF regulations. Various processing methods, including sewing, are available, allowing for large-diameter processing. Used for high-temperature duct seals.
basic information
Processing Method (Laser Processing) This is a machine tool developed for applications that perform machining impossible with conventional cutting tools or devices by cutting and slicing metals and resins with laser light. Since it processes 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 casts, which was previously necessary, has been eliminated, allowing for a variety of processing options.

Applications/Examples of results
Q&A Q: Why did you adopt laser processing for gaskets used in high-temperature ducts? A: By not using molds, we can consistently reproduce flange hole positions and outer shape accuracy, which aims to prevent misalignment during assembly. Q: Can you accommodate small lots and changes to drawings? A: Since laser processing is mold-free, we can flexibly respond to prototyping, small lots, and shape changes. Q: Is it possible to consult about use in high-temperature environments? A: We respond from the stage of material selection and shape consideration, taking into account the usage temperature and installation conditions. Daiko's responsiveness At Daiko, we provide comprehensive support from material selection and processing method proposals to shape considerations, starting with gaskets for high-temperature environments. Utilizing laser processing, we can flexibly accommodate prototyping, small lots, and custom shapes.
