Our advanced prefab house assembly line represents the cutting edge of industrialized construction technology, spanning 50,000 square meters of computer-controlled production space. The automated process begins with laser-guided steel stud fabrication where CNC machines cut and punch framing components with ±1mm precision. Robotic welding stations assemble structural panels while vision systems verify dimensional accuracy before progression. A dedicated electrical pre-fabrication station installs complete wiring harnesses with embedded conduits using automated routing equipment prior to wall closure. The ceiling and floor cassette line produces structural panels with integrated MEP services, while the roofing station assembles complete truss systems with pre-installed waterproofing membranes. The finishing department features robotic drywall installation systems and automated spray texture applicators for consistent surface quality. Quality assurance checkpoints occur at 15 critical stages, employing laser scanning for dimensional verification and pressure testing for envelope integrity. Our digital twin system provides full traceability, tracking each component from raw material to final assembly with embedded RFID tags. The lean manufacturing layout allows parallel production of multiple house modules simultaneously, with a typical throughput of 25 complete modules per week. For large-volume projects, dedicated production cells can be established to maintain specialized configurations. The facility incorporates Industry 4.0 technologies including predictive maintenance systems, real-time production monitoring, and automated material handling. Industrial partners may schedule facility tours to witness our fully integrated digital-physical production system in operation, demonstrating how precision manufacturing delivers consistent quality in prefabricated housing.
