Design. Engineer. Manufacture.
We make your cable innovations real.
At Nien-Yi Group, we are more than a cable supplier—we are a full-service OEM/ODM partner trusted by global clients across aerospace, EV, industrial automation, telecommunications, medical, and high-performance computing sectors. From design concept to production, we deliver engineered connectivity solutions that meet the most demanding requirements for electrical performance, mechanical durability, and international compliance.
What sets Nien-Yi apart is our deep integration of design, engineering, and manufacturing capabilities. Our team brings extensive expertise in mechanical cable structure design, developing optimized conductor layouts, shielding architectures, jacketing materials, and strain relief systems tailored to specific use cases. Whether it's a high-voltage EV cable, a precision coaxial assembly, or a lightweight aerospace harness, our engineers can customize everything down to connector interface and tooling design.
On the electrical side, we apply rigorous signal integrity and EMC design principles to every project. Our engineers ensure each cable assembly delivers consistent data and power performance, even in high-speed or high-power environments. We fine-tune impedance, optimize high-frequency transmission paths (USB, HDMI, CAN, Ethernet, ARINC), and ensure each product meets the highest safety and reliability standards.
Our vertically integrated factory includes advanced extrusion lines, molding stations, precision crimping machines, and automated inspection systems. This enables us to maintain strict process control and scale production efficiently—while still accommodating highly customized, low-volume, or quick-turn orders. We also develop our own molds, dies, and jigs in-house to support custom overmolded connector solutions and unique interface designs.
Every Nien-Yi cable is thoroughly validated in our in-house testing and compliance lab, ensuring full performance under stress. We perform electrical testing (continuity, resistance, dielectric strength), mechanical testing (flexibility, tensile, bending), and environmental testing (vibration, salt spray, high/low temp, humidity). Our cables are certified to meet UL, CSA, CE, VDE, RoHS, REACH, MIL-STD, ISO, and many other international standards. Cleanroom environments and full traceability systems are available for aerospace, medical, and defense applications.
From 2D/3D CAD development and simulation to material science and precision tooling, we offer an end-to-end OEM/ODM solution tailored to your exact application.
If you're looking for a cable partner that offers flexibility, engineering depth, and proven manufacturing quality, Nien-Yi Group delivers at every level.
