Built Around Your Drawings, Samples and BOM Files
WireLoomTech does not rely on fixed catalog products. Most projects are reviewed and manufactured according to customer-provided drawings, samples, BOM files, connector part numbers, wire specifications, pinout and testing requirements.
Send Project Files
Drawings, wiring diagrams, BOM files, samples or photos help us understand the product structure.
Confirm Specifications
Connector interface, wire gauge, cable length, pinout, labels, protection method and quantity are reviewed before quotation.
Move to Prototype or Production
After key details are confirmed, we can discuss prototype samples, small batch production or repeat manufacturing.
Manufacturing Support from Shenzhen, Hunan and Jiangxi
WireLoomTech operates production facilities across Shenzhen, Hunan and Jiangxi, China. Our Shenzhen facilities support active production and fast project communication in the Pearl River Delta region, while our Hunan and Jiangxi production bases support stable repeat manufacturing and capacity planning.
Inspection and Testing Based on Project Requirements
Quality control for custom wire harness and cable assembly projects may include incoming material review, in-process inspection, visual checks, continuity testing, polarity testing, pinout verification and packaging review according to confirmed requirements.
Continuity Testing
Confirm required electrical paths according to project specifications.
Polarity Testing
Check positive, negative and direction-sensitive connections when required.
Pinout Verification
Review connector pin position, wire sequence and circuit routing.
Crimping Review
Check terminal position, crimping appearance and assembly details.
Visual Inspection
Review appearance, labels, sleeves, connector direction and sample matching.
Packaging Check
Confirm quantity, labels, grouping, bags, cartons and shipment preparation.
Quality & Certification Support for Custom Wiring Projects
WireLoomTech can review UL, CE, CQC and ISO 9001 documentation needs for selected wire, cable, wire harness and cable assembly projects according to wire type, product structure, target market and customer specification.
UL Wire Documentation
Selected UL-recognized AWM wire style documentation can be reviewed for applicable harness and cable assembly projects based on required wire type, marking and end-use application.
CE Documentation Support
CE-related documentation requirements can be discussed during RFQ review for projects intended for European-market equipment or customer-specific compliance needs.
CQC Product Certification
CQC product certification documentation can be reviewed for selected connecting wiring and electronic or electrical equipment wiring products when applicable.
ISO 9001 Quality Management
ISO 9001 quality management documentation supports manufacturing, inspection and production-control communication for custom wiring projects.
