OEM/ODM RF Coaxial Cable Manufacturer & Custom Extrusion Factory
As a specialized RF coaxial cable manufacturer and premier cable extruding factory, HiFlexLink focuses on manufacturing high-precision bulk cables from scratch. While many vendors only provide wire harness assembly, we control the entire process from conductor drawing, insulation extruding, to shielding and jacketing. Whether you need custom micro-coaxial cables, semi-rigid cables, or specialized multi-core composite cables, our advanced extruding workshop delivers strict impedance control and world-class signal integrity.
Shenzhen HiFlexLink Technology Co., Ltd. (HiFlexlink for short), established in 2022, is located in Shenzhen. Backed by two decades of industry expertise and technical know-how from a Fortune Global 500 company, Hiflexlink is dedicated to advancing domestic high-end cable manufacturing and reducing dependency on foreign technologies.
Guided by the vision of “Connect with Global Top Market, Break the Limit,“
we are committed to innovation and excellence.
