5. 5. Global Logistics: Exporting to over 50 countries with custom OEM branding, export-grade packaging, and fast lead times.   

Our state-of-the-art production base integrates molding, skiving, extrusion, and sintering processes to form a complete PTFE sheet factory system with independent workshops for standard and custom production. Equipped with automatic compression presses, high-precision calenders, and advanced inspection instruments, we produce high-performance PTFE sheets in various specifications with consistent thickness and superior surface quality.   As an experienced PTFE manufacturer and global PTFE supplier, our facility features specialized production lines for ePTFE sheets, sealant tapes, braided packing, and custom sealing gaskets engineered for harsh chemical and thermal environments. Recognized among reliable gland packing suppliers and leading ePTFE manufacturers, our integrated manufacturing setup enables us to seamlessly execute raw material blending, preforming, paste extrusion, compression molding, skiving, and high-temperature sintering all under one roof:

1. 1. Extruder Machines: Converts pre-blended PTFE fine powder into continuous solid profiles, capable of producing high-density rods, tubes, and custom shapes.   
2. 2. Compression Molding Presses: Compresses PTFE powder or preforms under precise temperature and pressure controls to form blanks, thick plates, blocks, and complex molded components.   
3. 3. Precision Skiving Machines: Lathe-based skiving equipment engineered to peel ultra-thin, uniform PTFE films, skived sheets, and tapes.   
4. 4. Sintering Furnaces: Computer-controlled temperature profiles to fully fuse and crystallize PTFE particles after extrusion or molding for optimal mechanical strength.   
5. 5. CNC Machining Centers & CNC Lathes: High-precision machining of sintered PTFE blanks, enabling the custom production of tight-tolerance gaskets, intricate geometries, valve seats, and engineering seals.   

Spanning an area of 23,000 square meters with more than 130 experienced employees, our facility operates as a leading PTFE manufacturer and global PTFE supplier.
