Fluorine Plastic (Teflon) Extrusion Lines

The Fluorine Plastic Extrusion Line is designed for the precision insulation of electronic wires and cables using fluoropolymer compounds — a material family that requires highly specialized processing conditions and equipment configurations that differ substantially from conventional thermoplastic extrusion. Applicable materials include FEP, PFA, ETFE, and other fluorine-based resins, all of which are characterized by high processing temperatures, corrosive decomposition by-products, and narrow rheological processing windows that demand precise control at every stage of the extrusion process. Processing temperatures for fluoropolymers typically exceed 350°C, placing extreme demands on barrel and screw metallurgy, die materials, and sealing systems. The machine is constructed with materials selected specifically for resistance to hydrofluoric acid and other corrosive decomposition products generated during high-temperature fluoropolymer processing. The screw and barrel assembly uses specialized alloy construction with surface treatments that maintain dimensional stability and corrosion resistance across extended production runs. The extrusion head and die system are designed for the demanding concentricity requirements of electronic wire insulation. 
Fluoropolymer-insulated wire is used extensively in aerospace, military electronics, medical devices, and high-frequency data transmission applications where dimensional precision directly affects electrical performance. Wall thickness uniformity, concentricity, and surface smoothness are monitored and maintained through an integrated closed-loop control system that adjusts process parameters in real time. Exhaust and ventilation provisions are incorporated into the line design to safely manage the corrosive gases that may be released during the heating and extrusion of fluoroplastic compounds, protecting both operator safety and equipment longevity. This extrusion line is the right production tool for manufacturers of aerospace-grade wire, coaxial cable cores, medical-grade cable insulation, and high-speed data cable components where fluoropolymer performance properties are non-negotiable.
