China's professional manufacturer of prefabricated container houses, leading the industry's development direction
Our factory ensures the quality of container house products and implements the following five-step operation process during the production process
Step 1: Raw Material Inspection
Before production begins, all raw materials (e.g., steel, insulation materials, panels) are thoroughly inspected. Verify compliance with design specifications and national standards, check supplier quality certificates, and conduct sample testing (e.g., strength, dimensions, corrosion resistance). Non-compliant materials are returned or replaced.
Step2: Production Process Monitoring
Implement real-time monitoring and documentation on the production line. Each production stage (e.g., cutting, welding, assembly) is overseen by dedicated personnel to ensure process parameters (e.g., welding temperature, cutting precision) meet technical requirements. Use testing equipment (e.g., ultrasonic flaw detectors) to ensure the quality of critical components.
Step 3: Modular Assembly Inspection
Container house factories use modular production. After assembly, each module undergoes comprehensive inspection, including structural integrity, dimensional accuracy, connection stability, and waterproofing performance. A checklist is used to ensure no omissions, and all results are documented.
Step4: Finished Product Testing and Validation
Once all modules are assembled into a complete factory, conduct overall performance tests, including load-bearing capacity, wind resistance, thermal insulation, and electrical system safety. Simulate real-world conditions (e.g., wind and rain tests) to verify durability. Test data is archived for traceability.
Step 5: Final Pre-Delivery Audit
Before delivery, a final quality audit is conducted. The quality management team reviews all production and testing records to confirm no defects or issues remain. A quality certificate is issued, accompanied by a detailed quality report for customer reference. Products are re-inspected before packaging and shipping to ensure no damage.
