Custom Cable Assemblies: Precision Solutions for Medical, EV & Energy

The manufacturing of custom cable assemblies at Dongguan Nangu Di Electronics Co., Ltd. is a testament to precision engineering and rigorous quality control. Our facility in Humen, Dongguan, spans 12,000 square meters, housing 350+ professionals dedicated to delivering excellence. We have invested heavily in advanced machinery, including automated wire stripping, crimping, and soldering equipment, ensuring consistent quality across high-volume production runs. Our in-house testing laboratory is equipped with capabilities for impedance testing, tensile strength analysis, and environmental stress screening, guaranteeing that each custom cable assembly meets the most demanding specifications.
Our engineering team, comprising 35 specialists with an average of 10 years of industry experience, collaborates with clients from initial concept to final production. We utilize DFM (Design for Manufacturability) principles to optimize the cost and performance of your custom cable assemblies. Through computer-aided design and rapid prototyping, we can significantly reduce development lead times. For example, a recent project for an industrial automation client required 15 custom cable assemblies with specific shielding and bend radius requirements. We delivered working prototypes in just 5 days and mass production within 3 weeks, enabling the client to meet a critical product launch deadline.
We take pride in our vertically integrated production process, from wire cutting and stripping to connector termination and overmolding. This integration not only reduces costs but also ensures traceability and consistency. For every batch, we perform 100% electrical testing and visual inspection, backed by a statistical process control system. As a result, our product qualified rate consistently stands at 98%, and we maintain a defect rate below 100 parts per million (ppm) for major automotive customers.
In addition to manufacturing, we offer value-added services such as custom labeling, packaging, and global logistics. We have established a subsidiary in Hong Kong, facilitating seamless international trade. Our clients benefit from our strong supply chain partnerships, ensuring timely procurement of high-quality raw materials. We adhere to RoHS and REACH directives, reflecting our commitment to environmental sustainability. To support customers in different time zones, our account management team provides responsive communication and project updates.
Our expertise extends to specialized sectors. In the medical industry, we produce ISO13485-compliant cable assemblies for devices like patient monitors and surgical equipment. For automotive, our IATF16949-certified processes ensure ruggedness and long-term reliability in vehicle environments. In renewable energy, we supply high-voltage connectors that withstand harsh outdoor conditions, contributing to global solar and wind energy projects. For consumer electronics, we offer miniaturized designs with high-speed signal transmission.
With a proven track record of over 20 years and 40+ patents, we are confident in our ability to handle complex custom cable assembly challenges. By partnering with us, you gain access to a dedicated R&D team, comprehensive certification, and a global footprint. We invite you to experience our one-stop solution for custom cable assemblies, where quality and innovation converge.
