Wire Harnesses
NAG’s wire harnesses support electronic equipment operating worldwide with high Japanese technological capabilities.
They are mainly components within marine equipment that require high precision and play a role in transmitting power and electrical signals.
Because these are flexible materials, their shape changes depending on the application and task, resulting in a complex structure, so adjustments are made manually.
At our company, we focus on improving the skills of our workers to provide products quickly and with high precision.
