Custom Wire Harnesses & Solutions
Custom wire harnesses are designed to organize, protect, and connect electrical systems across complex equipment.
Romtronic provides custom wire harness solutions that integrate wiring, connectors, routing, and protection into application-specific assemblies for automotive, medical, and industrial equipment.
Our wire harness programs support both development builds and scalable production, tailored to real-world application requirements.
Providing customised requirements
Every wire harness is defined by its electrical loads, mechanical structure, and operating environment. Romtronic supports fully customized wire harness solutions built according to customer drawings, technical specifications, and system integration requirements.
Customization capabilities include:
Wire types, gauges, and insulation systems
Harness topology, branch structures, and breakout positioning
Connector families, terminals, and locking mechanisms
Shielding, grounding, and EMI control designs
Sleeving, tubing, conduit, and strain relief integration
To initiate a project, customers typically provide drawings, electrical parameters, application descriptions, and expected production volumes for engineering evaluation.
Our wiring harness manufacturing process
Design and Prototyping
Custom designs are created to customer specifications, followed by prototyping to validate performance and ensure a proper fit.
Wire Processing and Pre-Assembly
Raw wires are cut and stripped, then prepared for assembly through threading silicone tubing and inserting connectors.
Crimping and Riveting
Terminals are crimped to wires using mechanical devices, and in some instances, rivets are used to ensure a secure connection.
Assembly and Final Assembly
Wires are assembled into their final form according to the drawings, including board layout, wiring, and packaging, and installing sizable corrugated tubing on the main line.
Quality Control and Electrical Testing
Finished products are inspected for dimensions and aesthetics to ensure compliance with specified standards. Subsequently, circuit continuity is verified using electronic testing instruments.
