Supports valve peripheral applications with water jet processing.
■Overview of Processing Example Product Name: Valve Surrounding Gasket / Dimensions: Outer Diameter 99φ × Thickness 0.5t, Central Hole 8φ, Bolt Holes 6.5φ × 6 Locations / This processing example features a circular gasket made from PTFE material. It is designed for use around valves, with a central hole and bolt holes arranged at six locations on the outer perimeter. High-precision hole processing was achieved through water jet cutting, without compromising the excellent chemical resistance of PTFE. Due to the non-thermal impact processing, it can be manufactured with stable quality while maintaining the material properties. ■Product Features PTFE (fluororesin) is a high-performance material with exceptional heat and chemical resistance. It withstands almost all acids, alkalis, and solvents, and has minimal leaching of impurities, making it widely used in food, pharmaceuticals, and chemical plants where contamination is a concern. It also possesses non-stick and insulating properties, making it a highly reliable resin that maintains stable performance even in harsh environments.

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: Can you accommodate gaskets for valve applications? A: PTFE is excellent in chemical resistance, making it suitable for valve applications that handle corrosive fluids such as acids and alkalis. Q: Can you process multiple bolt holes with high precision? A: With water jet processing, it is possible to process six bolt holes at equal positions with high precision. Q: Is it possible to accommodate prototypes or small lot production? A: Since molds are not required, we can flexibly respond to prototypes and small lot production starting from one piece.
