Supports high-precision ring shapes with water jet processing.
■Overview of Processing Example Product Name: Silicone Rubber Gasket / Dimensions: 4t × φ82 × φ57 / This processing example features a ring-shaped gasket made from silicone rubber with a hardness of 70°. By adopting water jet processing, we achieved high-precision cutting without thermal impact while minimizing the deformation characteristic of rubber. Utilizing the excellent heat and cold resistance of silicone rubber, it is suitable for sealing applications in equipment used in a wide range of temperature environments. ■Product Features Silicone rubber (Si) is a special rubber with silicon as its main framework. It has exceptional 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 the cutting surface from press processing can also be improved with water jet processing. ■Q&A Q: Is it possible to process silicone rubber with specified hardness? A: We can accommodate various hardness levels, starting from 70°. Please specify your desired hardness. Q: Can it be used for food machinery and medical devices? A: Silicone rubber has high safety for the human body and is widely used in the food and medical fields. Q: Is it possible to produce in small lots? A: Water jet processing does not require molds, so it can accommodate small lot production starting from a single prototype.
