In modern electronics, connectivity is everything. Whether in an electric vehicle, a medical imaging system, or an industrial control cabinet, every signal and power line depends on one critical system: the wire harness.
These intricate assemblies may never be seen by the end user, yet they are essential to the reliability and safety of every device they power.
Wire harness manufacturing involves designing, assembling, and testing bundles of cables and connectors that transmit electrical power and data within a product. Each harness is built according to precise electrical and mechanical specifications to ensure stable performance under demanding conditions.
A single harness can contain dozens—or even hundreds—of wires, each cut, crimped, labeled, and routed to fit perfectly within the product’s architecture.
Every project begins with an electrical schematic translated into a physical layout. Engineers consider current flow, connector types, bend radius, and environmental factors.
CAD and simulation tools like EPLAN or Zuken are used to model the harness and ensure it fits perfectly within the end product before physical production begins.
Wires are cut and stripped automatically to precise lengths. Conductors are selected based on voltage, current, and flexibility requirements.
Materials commonly used:
Terminals are crimped onto wire ends using automated presses, ensuring consistent mechanical strength and low-resistance connections. Each crimp is tested under load to confirm reliability.
Wires are grouped and secured using tapes, sleeves, or tubing according to layout boards or digital assembly instructions. Harness boards act as 1:1 physical templates ensuring accuracy.
