Processing examples of silicone rubber fan-shaped gaskets
Supports complex shapes with a water jet.
■Overview of Processing Example Product Name: Fan-Shaped Gasket / Dimensions: R178×R117, Thickness 3mm, φ7 holes at 4 locations, with inner and outer radii / This processing example features a fan-shaped gasket made from silicone rubber. It was manufactured for mounting on a leveling plate. The gasket has a complex fan shape with different curvatures on the inside and outside, and requires machining of four bolt holes, so water jet processing was selected. The non-contact cutting with high-pressure water prevents thermal effects and deformation on the rubber material, resulting in smooth curves. ■Product Features Silicone rubber (Si) is a special rubber with a silicon-based main framework. It has excellent heat resistance (up to 200°C) and cold resistance (down to -70°C), demonstrating stable performance over a wide temperature range. It also has high weather resistance, electrical insulation properties, and safety for human contact, making it widely used as a sealing material in the food and medical fields, as well as in high-temperature environments, although its mechanical strength is relatively low.
basic information
■Processing Method Water jet cutting is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the injection nozzle according to the processing material, high-quality products can be produced in a short time. Additionally, the dimensional tolerances that are significantly improved compared to traditional manual processing result in stable processing accuracy. The taper on cut surfaces from press processing can also be improved with water jet processing. ■Q&A Q: What is the temperature range for using silicone rubber gaskets? A: Silicone rubber can be used over a wide range from -70°C to 200°C. It can accommodate equipment in high-temperature environments and cold regions. Q: Can you process curved shapes like fan shapes with precision? A: Water jet processing cuts with high precision based on CAD data, so curves and complex shapes can be finished smoothly. Q: Is it possible to place orders for small lots? A: Prototyping and small lot orders can be accommodated from just one piece. Since water jet cutting does not require molds, production can be done at a lower cost even for small quantities.
