Company introduction
Wenzhou Fudel Sealing Technology Co., Ltd. Has been dedicated to the sealing technology sector for over 15 years and is a high-tech enterprise integrating polymer material R&D, precision mold design, composite process manufacturing, and systematic testing. Our business scope spans a wide range of demanding industrial applications-including fluid pumps and valves, biopharmaceuticals, electronics and semiconductors, automotive components, medical devices, liquid cooling pipelines, petrochemicals, and deep-sea equipment-dedicating itself to providing global OEM/ODM manufacturers, end-users, and engineering service providers with one-stop solutions covering everything from individual sealing components to complete fluid sealing systems. Our core product portfolio encompasses the full range of rubber and plastic sealing solutions, including O-rings, star-shaped seals, general-purpose sealing components, diaphragms, gaskets, composite seals, and custom-shaped parts. In terms of material systems, we possess extensive expertise in the modification and processing of various polymer materials-such as fluororubber (FKM), ethylene-propylene-diene monomer (EPDM), silicone rubber (VMQ), polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), and polyurethane (PU). By combining our unique rubber-coated fluoropolymer, rubber-coated metal, metal-coated fluoropolymer, and servo-spraying composite manufacturing processes, we can deliver solutions tailored for harsh operating environments-including exposure to strong acids and alkalis, organic solvents, high-temperature steam, high-pressure gases, and abrasive slurries. Product features (unique advantages and verified performance data): Extreme environmental durability: We have supplied sealing components capable of withstanding ultra-high pressure (operating pressure up to 3, 000 psi, approximately 207 bar) to deep-sea production trees, utilizing a metal skeleton combined with a PTFE interlayer structure. These components achieved 30, 000 stable opening and closing cycles in a cyclic pressure testing regimen, with a leakage rate of less than 0.001 ml/min - representing an improvement of one order of magnitude over industry standards - ensuring smooth operation of low-temperature valves; We also design sealing gaskets for thermal pipelines capable of withstanding ultra-high temperatures (350°C), employing a graphite-composite PTFE manufacturing process; In continuous high-temperature aging tests, the compressive strength degradation rate was less than 8%, extending the service life to 2.5 times that of conventional graphite gaskets. Backed by an in-house R&D laboratory: We operate a materials and finished product testing center spanning over 200 square meters, equipped with state-of-the-art instruments including a universal tensile testing machine, a high-and low-temperature impact testing chamber (-70°C to +400°C), a vulcanization curve analyzer, a fully automated medium immersion system, an optical microprofilometer, and a helium mass spectrometry leak detector. Finished products undergo comprehensive dimensional inspection, voltage burst testing, and simulated operating condition validation in accordance with ASTM/GB/DIN standards. Trust endorsement: Case Study (Pump and Valve Sector): A major domestic petrochemical group previously used imported skeleton oil seals for its high-temperature residue oil pumps; These seals required replacement due to leakage approximately every 45 days, resulting in significant spare parts costs. Following an on-site inspection by our engineers, we recommended the use of FKM-lined stainless steel composite seals and optimized the groove design. After this replacement, the pump operated continuously without any failures for 170 days, saving over RMB 1, 200, 000 annually in spare parts and maintena
