Supports multi-hole ring processing of ultra-thin materials using water jet cutting.
■Overview of Processing Example Product Name: Three-Sheet Thin Gasket / Dimensions: Outer Diameter φ135 × Inner Diameter φ100 × Thickness 0.22mm, 6-φ7 Holes (PCD116) / This processing example features a ring-shaped gasket made from an ultra-thin three-sheet with a thickness of 0.22mm. High-precision processing is achieved through water jet cutting, minimizing deformation and warping even with thin materials. Utilizing the property of the viscous material to fill in unevenness during tightening, it is adopted as a leak prevention measure for flanges in hydraulic equipment and industrial machinery. ■Product Features The three-sheet packing is a special sheet-like gasket developed by leveraging the advantages of traditional solid sheet gaskets and liquid gaskets. It exhibits excellent resistance, particularly to oils. When compressed between mating surfaces, the viscous material contained within oozes out to the surface, filling in the uneven areas and preventing leakage from the joint surface. Unlike traditional solid sheet gaskets, which rely solely on resilience to prevent leakage, this gasket provides a long-lasting leak prevention effect.

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 injection nozzle according to the processing material, it is possible to produce high-quality products in a short time. Additionally, the dimensional tolerances that are significantly improved compared to traditional manual processing result in stable processing accuracy. The taper of the cut surface from press processing can also be improved with water jet processing. ■Q&A Q: Is it possible to process ultra-thin materials (around 0.2mm)? A: Yes, it is possible. Water jet processing has no thermal effects, allowing for stable processing even with ultra-thin materials that are prone to deformation and warping. Q: Can it be used for hydraulic equipment applications? A: Yes. The three-seat has excellent resistance to oils, and during tightening, the viscous material fills in the irregularities, making it effective for preventing oil leaks. Q: Can you accommodate multi-hole processing specified by PCD? A: Yes, we can accommodate that. We accurately process hole positions based on the drawings from CAD data, preventing positional misalignment during assembly.
