Wire Harness Manufacture | Custom Solutions for EV, Medical & Auto

Wire harness manufacture is a critical process that ensures electrical systems function seamlessly across industries. At Dongguan Nangu Di Electronics Co., Ltd., we have been perfecting this craft since 2006, serving global clients with custom-engineered wiring solutions. Our factory, spanning 12,000 square meters, houses state-of-the-art machinery that allows for precision cutting, stripping, crimping, and molding. Our team of 350+ professionals, including 35 dedicated R&D engineers, brings over a decade of experience to every project. This expertise enables us to handle complex requirements, from high-voltage electric vehicle harnesses to ultra-miniature medical devices.
Our production process begins with understanding the client's application and technical specifications. We then design a prototype using advanced CAD software, followed by rigorous testing to ensure compliance with industry standards like UL, IPC, and custom tolerances. Our in-house testing facilities include thermal cycling, vibration, tensile, and high-voltage testing, guaranteeing that each harness can withstand harsh environmental conditions. For instance, our automotive harnesses undergo 1,000-hour salt spray tests, while medical harnesses are tested for biocompatibility as per ISO 10993.
Data-driven quality control is at the core of our operations. With a 98% first-pass yield and 99.5% on-time delivery rate, we consistently meet the demands of international clients, including those in Germany, Japan, and the United States. Our certifications (ISO9001, ISO13485, IATF16949, UL) demonstrate our commitment to quality and safety. Moreover, our 40+ patents reflect our innovative approach to wire harness design, enabling us to offer solutions that reduce weight, improve signal integrity, and lower costs. For example, we developed a unique crimping technique that increased terminal pull-out force by 30% without compromising conductivity.
In the new energy sector, we produce high-voltage harnesses for electric vehicles and energy storage systems, with ratings up to 1000V and 300A. Our photovoltaic harnesses are engineered to deliver maximum power conversion efficiency, as seen in a recent project where we contributed to a 20% increase in solar farm output. In the medical field, our ultra-low-leakage cables ensure accurate patient monitoring, and our clean-room manufacturing processes meet ISO Class 8 standards.
We understand that each industry has unique demands, which is why we offer extensive customization options. From connector selection to wire gauges, lengths, and insulation materials, we tailor every aspect to your specifications. Our one-stop service includes design support, rapid prototyping (often within 72 hours), and agile production for both small and large batches. We also provide value-added services like cable assembly, overmolding, and custom labeling, streamlining your supply chain.
Global clients trust us for our transparent communication and engineering expertise. Whether you require a complex aerospace harness or a cost-effective consumer electronics cable, our team is dedicated to delivering reliable, high-performance solutions. With a production capacity of 1.8 million harnesses per month, we are equipped to scale with your business. Our strategic location in Dongguan, a global electronics hub, offers quick access to components and efficient logistics, ensuring competitive lead times.
Furthermore, we are committed to sustainability. Our manufacturing processes are designed to minimize waste, and we use RoHS-compliant materials to protect the environment. This eco-conscious approach aligns with the values of many international clients, helping them meet their corporate social responsibility goals.
In conclusion, our expertise in wire harness manufacture is backed by nearly two decades of experience, cutting-edge facilities, and a relentless pursuit of quality.
