We build custom jigs and prototypes to validate every design, ensuring that whether it’s a single wiring loom or a complex harness, the solution fits perfectly within your product.
The following are various industrial cable and wire harness assembly styles we customize for our customers
Quality and reliability
We adhere to strict quality standards in all production stages. Our factory holds ISO 9001, ISO 13485, and IATF 16949 certifications, ensuring consistently high workmanship. Every cable assembly undergoes rigorous inspection and electrical testing – we target a 300% inspection rate and zero defects, and we even guarantee on-time delivery (with penalties for late shipments). We use premium components (Amphenol, Molex, JST, etc.) and robust jacketing to withstand heat, moisture, abrasion, and vibration. In fact, Romtronic’s materials protect wires in harsh environments, offering high-temperature, dustproof, and corrosion-resistant properties. The result is wiring you can trust in critical industrial settings.
Fast turnaround and service
Time-to-market is critical in industrial projects. Romtronic offers lightning-fast support – our team is available 24/7 and typically responds to inquiries within 12 hours. We accept small production runs (MOQs starting from 10 pieces or a total of just $100), allowing you to test prototypes quickly. We scale up to high-volume orders as needed, using automation for rapid production. Clear project communication and online tracking keep you informed at every step. By combining quick quotes, 24/7 assistance, and guaranteed on-time delivery, we act as a true partner (not just a supplier) to engineers and purchasing teams alike.
