Manufacturing Standards & Capabilities

ISO 9001 Certified Factory

TeleWire Technology operates under strict ISO 9001 Quality Management Systems. Every production run undergoes rigorous IQC (Incoming Quality Control) and IPQC (In-Process Quality Control) to ensure consistent, OEM-grade reliability for global supply chains.

IPC/WHMA-A-620 Compliance

Our assembly technicians adhere to IPC/WHMA-A-620 standards for cable and wire harness fabrication. We guarantee precision crimp height, pull-force retention, and strain relief integrity for high-vibration automotive and industrial environments.

100% Electrical Testing

Zero defect policy. 100% of finished assemblies undergo automated testing for continuity, shorts, and mis-wiring. For critical safety applications, we provide advanced VSWR testing, high-pot testing, and insertion force validation.

Custom Component Sourcing

We source genuine connectors from Amphenol, TE Connectivity, Molex, and JST, or provide cost-effective, high-quality equivalents to meet your BOM targets. Our engineering team supports rapid prototyping with low MOQs and fast turnaround times.
