Processing examples of fluororubber frame gaskets
Processing examples of fluororubber frame gaskets | Responding to inner R shapes with water jet processing
■Overview of Processing Example Product Name: Fluororubber Frame-Shaped Gasket Dimensions: 188W × 748L (Frame Width 38W) This processing example involves the fabrication of a frame-shaped gasket made from fluororubber material. The long, elongated outer perimeter is equipped with multiple mounting holes, and the interior features an opening, creating a frame structure with specified R-shaped inner corners. To avoid stress concentration during assembly, the product requires shape reproducibility and precision of the inner R. The client's industry is related to thermal equipment and industrial devices. The characteristics of this product include its use of fluororubber for chemical and heat-resistant applications, and the design that incorporates an R shape on the inside of the frame, which takes into account the sealing area's fit and durability. The processing method employed is water jet cutting. Since fluororubber tends to show edge irregularities with blade processing, non-contact processing is used to fabricate the inner R shape according to the specifications, thereby stabilizing shape accuracy and reproducibility.
basic information
■Product Features (Fluoro Rubber) Fluoro rubber (FKM) is a material that ranks at the pinnacle of synthetic rubber. It boasts exceptional performance in heat resistance (up to 250°C), oil resistance, and chemical resistance. It can be used stably even in harsh environments, making it indispensable as a critical component in chemical plants and semiconductor manufacturing equipment; however, attention must be paid to its cold resistance and price. ■Processing Method (Water Jet Cutting) Water jet cutting is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. The injection nozzle can be changed according to the processing material, allowing for the production of high-quality products in a short time. Additionally, the dimensional tolerances that are typically achieved through manual processing are significantly improved, resulting in stable processing accuracy. The taper of the cut surface from press processing can also be improved with water jet cutting.
