INDUSTRY KNOWLEDGE
Teflon Wire & Cable Extrusion Line is a core product series developed by Jiangsu Newtopp Precision Machinery Co., Ltd.—a National High-Tech Enterprise with over a decade of experience in high-end cable equipment R&D and manufacturing. This specialized line is engineered for micro-fine coaxial wires, high-frequency signal transmission wires, and other cables requiring Teflon (PTFE) insulation extrusion, integrating Newtopp’s precision manufacturing technology and space-saving design philosophy. As a key part of Newtopp’s extruder product portfolio (alongside core/jacket extruders and foam extruders), the Teflon Wire & Cable Extrusion Line delivers consistent performance in insulation precision, temperature control, and operational efficiency, meeting the strict requirements of data transmission, automotive, new energy, and industrial cable production.


1. Working Principle of Teflon Wire & Cable Extrusion Line

Teflon insulation extrusion relies on the unique thermal stability and chemical inertness of PTFE materials, combined with precision mechanical control to achieve uniform insulation coating. The core working principle is as follows:
  1. Material Preparation: Teflon resin is preprocessed to remove moisture and impurities, ensuring extrusion uniformity—Newtopp’s production process adheres to ISO9001 quality standards, with raw material preprocessing equipment integrated into the line for seamless workflow.

  2. Precision Extrusion: The processed resin is fed into an extruder barrel equipped with a copper casting heater (a standard component of Newtopp’s Teflon line). The SCR power control system and imported temperature control table regulate the barrel temperature within ±1℃, ensuring Teflon resin melts uniformly without degradation.

  3. Wire Core Coating: The molten Teflon is extruded through a precision die onto the moving wire core. Newtopp’s whole-machine precision design (from pay-off to take-up) maintains stable online tension, preventing wire core deviation and ensuring insulation concentricity exceeds 95%.

  4. Cooling & Shaping: The extruded cable is rapidly cooled to solidify the Teflon insulation, with the capstan and take-up integrated into a box structure (a signature design of Newtopp’s Teflon line) to maintain consistent tension during cooling, ensuring an OD tolerance of ±0.003mm.

    Precision Take-up: The integrated take-up unit, part of the line’s space-saving design, neatly winds the finished cable, completing the Teflon insulation extrusion process—all core components are manufactured in Newtopp’s 50-acre production base, featuring an independent finishing center for precision machining.
