Welcome to our Cable Extruding workshop.This will give you an rough idea about rf coaxial cable extruding.As a leading RF Coaxial Cable Manufacturer, our state-of-the-art production facilities are engineered to deliver high-performance cables tailored for telecommunications, aerospace, industrial IoT, and 5G applications. Our manufacturing process integrates advanced equipment and stringent quality controls to ensure compliance with international standards like MIL-C-17, GB/T 14864, and RoHS directives.

Core Production Equipment & Expertise

Conductor Processing: Utilizing precision wire drawing machines and multi-strand twisting systems to craft center conductors from oxygen-free copper or copper-clad aluminum, ensuring minimal signal loss and optimal conductivity.

Insulation Layer Extrusion: High-frequency extrusion lines apply uniform PTFE (polytetrafluoroethylene) or foamed PE/PFA insulation, achieving precise dielectric constants (ε) for stable impedance (50Ω/75Ω) and low attenuation.

High-Velocity Dielectric Coating

Our high-frequency extrusion lines apply uniform PTFE or foamed PE/PFA insulation directly onto the conductor. This process achieves precise dielectric constants crucial for guaranteeing stable 50ohm or 75Ω characteristic impedance and ultra-low attenuation.

precision micro coaxial cable extrusion manufacturing equipment — State-of-the-art high-speed wire drawing and PFA extrusion lines ensuring consistent electrical geometry.

Consistent Electrical Geometry

Equipped with real-time laser diameter gauges, our automated production setup monitors insulation thickness continuously. This ensures microscopic geometric consistency throughout the entire spool, preventing signal distortion in microwave applications.

Shielding Technology: Automated braiding machines layer tin-plated copper or aluminum-magnesium alloy shields with >95% coverage, effectively suppressing EMI/RFI interference while enhancing mechanical durability.

Heavy-Duty Production Lines

Operated in a fully controlled climate, our continuous jacket extrusion lines are optimized for high-temperature resins. This industrial-scale infrastructure guarantees scalable monthly capacity while maintaining flawless structural integrity for cables deployed in harsh, corrosive, or extreme-temperature environments.

Quality Assurance

Every cable undergoes rigorous testing, including VNA (Vector Network Analyzer) validation for impedance matching, TDR (Time-Domain Reflectometry) for signal integrity, and environmental simulations for thermal/mechanical resilience.

Signal Integrity Validation

Every batch of RF cables undergoes rigorous validation using Vector Network Analyzers (VNA) and Time-Domain Reflectometry (TDR). This guarantees precise impedance matching, low VSWR, and flawless transmission performance before shipment.
