Processing example of V7030(N) Teflon cushion irregular gasket.
Supports multi-hole and R processing with water jet machining.
■Overview of Processing Example Product Name: V7030(N) Teflon Cushion Gasket / Dimensions: 120W × 250L × 2.8t / This processing example involves a product that has been water jet processed from a Teflon cushion gasket with a PTFE coating structure. Two circular openings with a diameter of 80mm, ten bolt holes with a diameter of 14mm, and a complex shape with rounded corners (R20) were processed with high precision. Water jet processing was selected to enable complex external shapes and multi-hole processing while maintaining the coated structure, achieving stable quality for gaskets used in corrosive fluids and food and pharmaceutical applications. ■Product Features V7030(N) is a composite gasket that has a resilient core material, such as a non-asbestos joint sheet, coated with PTFE in a V-shaped cross-section. Thanks to the excellent chemical resistance of PTFE, it can handle corrosive fluids such as acids and halogens, making it safe for use in the food and pharmaceutical sectors, which are sensitive to contamination. It is widely used for sealing pipe flanges, towers, tanks, and various equipment.
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 spray 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 cut surface from press processing can also be improved with water jet processing. ■Q&A Q: Can you process while maintaining the coating structure of Teflon cushioning material? A: Water jet processing is non-contact and has low thermal load, allowing for high-precision processing without damaging the PTFE coating structure. Q: Can you accommodate multi-hole processing and curved or R-shaped processing? A: Based on CAD data, we can flexibly accommodate complex irregular shapes such as multiple holes and corner R processing. Q: Can it be used for corrosive fluids and food applications? A: V7030(N) is a material suitable for strong corrosive environments and food and pharmaceutical lines that dislike contamination due to its PTFE coating.
