Overview
Anhui Xinfulong's large diameter molded products are manufactured using advanced compression molding and isostatic pressing technologies, delivering high-purity fluoropolymer components for demanding semiconductor, wet chemical, and industrial applications. Our product range includes large diameter molded pipes, fittings, lined vessels, and custom-engineered components — all produced in Class 1000/10,000 cleanrooms to ensure the highest levels of purity and quality.
Unlike jointed or extruded alternatives, our fully molded products are formed in a single pressing operation on precision tooling, eliminating weak points and ensuring superior mechanical performance, dimensional accuracy, and long-term reliability.
Key Features
-
Seamless, One-Piece Construction — Fully molded in a single operation, eliminating joints, seams, or welded connections that can become points of failure under thermal cycling or mechanical stress.
-
Superior Dimensional Accuracy — Tighter cross-section tolerances ensure proper fit in critical equipment, with consistent part dimensions and batch-to-batch uniformity.
-
Exceptional Corrosion Resistance — Manufactured from high-purity PTFE, PFA, or FEP, our large diameter molded products are inert to virtually all chemicals, acids, and solvents — ideal for the most aggressive process environments.
-
High-Purity Performance — Ultra-low extractables and no metal ion contamination, meeting the stringent cleanliness requirements of semiconductor, pharmaceutical, and ultra-pure chemical applications.
-
Superior Mechanical Strength — Compression molding and isostatic pressing produce dense, homogeneous material structures with excellent mechanical properties, including high compressive strength and resistance to deformation under load-.
-
Thermal Stability — Maintains structural integrity across a wide temperature range, with PTFE grades suitable for continuous service from -200°C to +260°C.
-
Cleanroom Manufactured — Critical production processes carried out in Class 1000 and Class 10,000 cleanrooms, ensuring the highest levels of purity and contamination control.
-
Custom Engineering — Available in a wide range of diameters, wall thicknesses, lengths, and configurations to meet specific process requirements.
