Custom Harness Assemblies | EV, Medical & Automotive

At Dongguan Nangu Di Electronics, we pride ourselves on being a national high-tech enterprise and a recognized "Little Giant" in Guangdong Province. Since 2006, we have dedicated nearly two decades to perfecting the art of custom wire harness assemblies. Our 12,000m² facilities in Humen, Dongguan, house over 350 professionals, including 35 R&D engineers who drive innovation in the industry. We hold ISO9001, ISO13485, IATF16949, and UL certifications, ensuring that every harness assembly meets the highest global standards.
Our production capabilities are second to none. We utilize automated wire stripping, crimping, and soldering machines, capable of producing up to 50,000 assemblies per day. Our in-house tooling and molding department enables rapid prototyping, reducing lead times by 30% compared to industry benchmarks. For example, we can ship samples within 48 hours for most custom designs. Quality control is embedded at every stage: incoming material inspection, in-process checks, and final testing. Our 98% first-pass yield and 0.5% field failure rate testify to our commitment to excellence.
We serve a diverse range of industries, from automotive and new energy to medical and solar. For electric vehicle manufacturers, we supply high-voltage harness assemblies that support up to 1000V and 300A, with optional waterproof connectors (IP68). For medical device makers, we offer ultraclean assemblies with PTFE or FEP insulation, compliant with ISO13485 and biocompatibility tests. In the solar sector, our assemblies feature UV-stabilized materials and corrosion-resistant connectors, ensuring 25-year performance in extreme conditions.
Our R&D team, averaging 10 years of experience, collaborates closely with clients to optimize design for manufacturability (DFM). We provide value engineering services that reduce material costs by up to 20% without compromising performance. For instance, we helped a client redesign a wiring harness for agricultural machinery, replacing a complex multi-part assembly with a single molded unit, cutting assembly time by 40% and weight by 15%.
Sustainability is also at our core. We use lead-free solder, recyclable insulation materials, and energy-efficient production processes. Our factory runs on 70% renewable energy, and we recycle 95% of production waste. By choosing our harness assemblies, you not only enhance your product's reliability but also contribute to a greener future.
