RONGAI is a full-category custom wire harness manufacturer based in Shenzhen, China. From head unit kits to board-level, lighting and power harnesses, we build the full range for brands, distributors and installation channels — in our own factory, to your drawings. TPMS systems run under the same roof.
We list what is verifiable and leave the rest blank until confirmed — the same standard we apply to specifications.
Equipment listed by process, not by brochure model number — what matters to your order is that every critical process sits under our own roof.
Automatic cutting and stripping machines for consistent length tolerance; manual stations cover short runs and specialty wire.
Terminal crimping and solder joints across common connector families, with pull and continuity checks on critical circuits.
Own vertical injection machines produce connector overmolds and strain reliefs — housing shapes and colors made for your brand.
Line-based assembly: taping, corrugated conduit, sleeving, branch bundling and label application per your installation documents.
Visual and functional checks before packing, with packaging designed for retail shelves or bulk export cartons.
Sensor pairing, calibration and functional testing for TPMS kits, with pre-paired configuration per vehicle project.
Factory visits are welcome by appointment, and a video call is an easy first step.
