Terminal Wire Solutions | High-Voltage, Medical & EV Grade

At Nangudi, our terminal wire manufacturing combines precision engineering with scalable production. We begin with material selection: high-conductivity copper (99.9% purity) or tinned copper for corrosion resistance. Our automated stripping and crimping processes ensure consistent terminal attachment, with pull-out force exceeding UL standards by 30%. For insulation, we offer PVC for cost-effective applications, PTFE for high-temperature environments (up to 260°C), and Neoprene for flexibility in harsh conditions. Our in-house tooling lab designs custom dies for unique terminal shapes, enabling lead times as short as 48 hours for prototypes. Using 3D measuring systems, we achieve dimensional tolerances of +/-0.05mm, guaranteeing reliable mating with connectors. Our production lines incorporate real-time monitoring of crimp height and tensile strength, with data logged for 100% traceability. We apply a 5-step quality gate: incoming material inspection, first article inspection, in-process testing (including continuity and hi-pot tests), final visual inspection, and functional testing under simulated loads. Our commitment to continuous improvement is reflected in our 98% first-pass yield and a PPM of less than 100. Serving global clients in new energy (battery packs, inverters), automotive (ECU, sensors), and medical (diagnostic, monitoring) sectors, we have shipped over 100 million terminal wires annually. Our dual facilities, ISO certifications, and 35 specialized engineers ensure we meet international standards (UL, CE, RoHS) and deliver high-end products with efficiency. Whether you need a standard or custom solution, Nangudi offers a one-stop experience: fast quoting, sampling, and mass production with global shipping.
