Examples of processing silicone sponge gaskets.
Supports complex shapes with a water jet.
■Overview of Processing Example Product Name: Silicone Sponge Packing / Dimensions: 208W × 305L × 5t, Hole Diameter φ7 × 10 Locations / This processing example features a packing made from silicone sponge (SSR930N). It has a special shape with two openings and ten bolt holes arranged around the outer perimeter. The water jet cutting process allowed for precise dimensional accuracy without compromising the unique flexibility of the sponge material. Silicone sponge is excellent in heat resistance and cold resistance, making it suitable for sealing applications in equipment. ■Product Features Silicone rubber (Si) is a special rubber with silicon as its main framework. It exhibits exceptional heat resistance (up to 200°C) and cold resistance (down to -70°C), maintaining 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 it has lower mechanical strength.
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 typically achieved through manual processing are significantly improved, resulting in stable processing accuracy. The taper on the cut surface from press processing can also be improved with water jet processing. ■Q&A Q: What is the temperature range for using silicone sponge? A: It can be used in a wide range from approximately -70°C to 200°C. Q: Why did you choose water jet processing? A: Since sponge materials are prone to crushing with cutting tools, we ensured shape accuracy with non-contact water jet cutting. Q: Is it possible to produce in small lots? A: Prototype and small lot production are possible starting from one piece.
