Supports multi-hole precision machining with water jet processing.
■Overview of Processing Example Product Name: Teflon-coated Packing (Core CR Rubber 2t) / Dimensions: 5K-900A Full Surface, Up to the Bolt Hole in the Outer Skin / This processing example is a ring-shaped packing for large diameter flanges. It features a multi-hole design with bolt holes arranged on the outer circumference, used for sealing at equipment connection points. The composite structure combines the chemical resistance of PTFE and the cushioning properties of CR rubber, providing stable sealing performance. The water jet processing minimizes thermal impact, allowing for high-precision machining of large diameter and multi-hole shapes. ■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 that require contamination prevention. 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 A water jet is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the spray nozzle according to the processing material, high-quality products can be produced in a short time. Additionally, the dimensional tolerances that were significantly affected by traditional manual processing are greatly improved, resulting in stable processing accuracy. The taper on the cutting surface caused by press processing can also be improved with water jet processing. ■Q&A Q: Is it possible to process large-diameter gaskets? A: We can accommodate products for large flanges equivalent to 5K-900A. Q: Can you ensure the accuracy of multi-hole processing? A: Water jet processing achieves high precision in hole position and pitch. Q: Is it possible to process composite materials (Teflon-coated structures)? A: We can process composite structures with PTFE outer skin and CR rubber core while maintaining material properties.
