Capabilities / Box-Build Assembly
Enclosure integration, wiring harnesses, conformal coating, functional testing and custom packaging — assembled, tested and boxed in our own 45,000 m² facility in Bao'an, Shenzhen. No third-party assemblers, no lost accountability between vendors.
Plastic, machined aluminium or sheet-metal enclosures. Heat-set inserts, standoffs, gasket and membrane keypad fitting. We work from your 3D files or from an existing enclosure you ship to us.
Cut, strip, crimp, tin and route to your drawing. Connector crimp pulled to spec, continuity verified per harness, labelled per your scheme so field service can trace every wire.
Selective spray and dip coating with masking for connectors, test points and optical areas. Acrylic, polyurethane and silicone chemistries. UV tracer for inspection under black light.
Firmware flashing, calibration, burn-in and full functional test against your checklist. We build the fixture if you need one, and keep the test record with the serial number.
Retail-ready cartons, foam inserts, printed manuals and labels to your artwork. Serialised labelling, drop-test validated cartons, and direct shipment to your customer or 3PL if you prefer.
Run entirely from your consigned stock, entirely from our sourcing, or any mix in between. Either way one BOM, one quote, one point of accountability for the finished unit.
We read your assembly drawing, harness drawing, test checklist and packaging spec before quoting. Anything missing or contradictory comes back to you as a question, not as a surprise later.
One to five units built and shipped to you for approval. Assembly sequence, torque values, wire routing and test limits are locked at this stage and written into the work instruction.
Work instruction at every station, in-process checks after each operation, and a traveller sheet that follows the unit from bare PCB to sealed carton.
100% functional test, visual inspection, packaging check, then shipment on your chosen Incoterm with the test records attached.
