Large integrated molded PTFE sealing frame and gasket

Features
Innovative Manufacturing: Overcoming the drawbacks of traditional methods involving cutting, splicing, and welding of sheet materials, this product is manufactured using a one‑piece molding, sintering, and CNC milling process. The entire structure is formed seamlessly without joints or welds, eliminating issues such as uneven seams, leakage risks, and weak strength associated with conventional welding techniques.
Wide Dimensional Range: Capable of producing monolithic circular gaskets (up to 4000 mm in diameter) and custom‑shaped rectangular/square sealing frames (total outer length ≤ 4000 mm), as well as tailored large‑format sealing components with irregular or special configurations.
Superior Performance: Uniform and stable structural integrity, smooth and flat sealing surfaces. Leveraging the excellent physical and chemical properties of fluoroplastic materials—resistance to acid and alkali corrosion, high‑temperature tolerance, and long‑lasting sealing performance—eliminates potential leakage and cracking at welded joints.
Applications
Chlor‑Alkali Chemical Industry: Large sealing frames for electrolytic cells and tank sealing gaskets;
Electronic Chemical Industry: Corrosion‑resistant flange gaskets for liquid storage tanks;
New Energy Sector: Specialized sealing gaskets for hydrogen fuel cell stacks;
Semiconductor Precision Equipment: Large non‑standard sealing frames for etching machines and cleaning equipment;
Suitable for specialized anti‑corrosion sealing requirements in various large‑sized, irregularly shaped, and non‑standard equipment.
