Processing examples of PTFE water service gaskets

Processing examples of PTFE water service gaskets

Processing example of PTFE water service gaskets | Press processing for 150A flanges

■Overview of Processing Example Product Name: PTFE Gasket for Water Supply Dimensions: 3t Water Supply 150A FF Material: PTFE Processing Method: Press Processing This processing example involves the production of a PTFE gasket used for the flange part of water supply equipment. The product features a full-face shape compatible with a 150A flange, with bolt holes arranged evenly. Since it is used for water supply applications, PTFE, which has low impurity leaching and excellent chemical resistance, is employed as the material. As this was a project intended for mass production, press processing was selected to achieve both dimensional reproducibility and processing efficiency. As a result, stable dimensional accuracy is ensured while minimizing positional misalignment during assembly, achieving reliable sealing performance.

Processing example of PTFE (Teflon) circular multi-hole gasket.

Processing example of PTFE (Teflon) circular multi-hole gasket.

Processing example of PTFE (Teflon) circular multi-hole gasket | Uneven pitch support through water jet processing

Processing Case Overview Product Name: Circular Multi-Hole Gasket Dimensions: Outer Diameter φ300 / Inner Diameter φ228 Material: PTFE 1t This case involves the processing of a circular gasket made of PTFE material, featuring multiple bolt holes arranged with an uneven pitch. The material was specified with a focus on chemical resistance, and the non-standard hole arrangement was addressed using water jet cutting. Product Features PTFE PTFE (polytetrafluoroethylene) is a high-performance material with exceptional heat and chemical resistance. It withstands almost all acids and alkalis, and has minimal leaching of impurities, making it widely used in industries that require contamination-free materials, such as food, pharmaceuticals, and chemical plants. It also possesses non-stick and insulating properties, providing reliable performance even in harsh environments. Processing Method (Water Jet Cutting) Water jet cutting is a method that uses high-pressure water to cut materials. It processes by spraying high-pressure water. The injection nozzle can be changed according to the processing material, allowing for the production of high-quality products in a short time. Additionally, the dimensional tolerances achieved through traditional manual processing are significantly improved, resulting in stable processing accuracy. The taper of the cut surface from press processing can also be improved with water jet cutting.
