Quality Control
A reliable wire harness requires more than simply connecting wires and terminals. Proper material selection, accurate assembly, secure crimping, and thorough electrical testing are all essential to product performance.
At XSD Harness, quality control is integrated into the manufacturing process.
Our inspection procedures include:
Incoming Material Inspection
Materials and components are checked according to project requirements before entering production.
First Article Inspection
Initial assemblies are reviewed to confirm that the production process meets the approved specifications.
Crimp Quality Inspection
Crimped terminals are checked to verify proper connection and mechanical integrity.
Pull Testing
Pull-force testing can be performed to evaluate the strength and reliability of wire-to-terminal connections.
Dimensional Inspection
Critical dimensions, wire lengths, stripping lengths, and assembly configurations are checked against customer specifications.
Continuity Testing
Electrical testing helps verify that circuits are correctly connected and free from open or incorrect connections.
Final Inspection
Finished harnesses are visually and functionally inspected before shipment to ensure they meet the agreed requirements.
Our quality objective is simple:
The right materials. The right connections. The right performance.
Certifications
XSD Harness is committed to quality and consistency and proudly holds ISO 9001&IATF 16949 certification as a manufacturer of high-quality electrical wiring harnesses and cables built to customer specifications.
