I. Precision Manufacturing Process System
1. Selection of Aviation - grade Aluminum Materials and Material Pretreatment
We select 5052/6061 - T6 aviation - grade aluminum plates with a thickness ranging from 1.2 to 1.5 mm, whose yield strength exceeds 215 MPa. These plates are processed by a fully - automated uncoiling and leveling line with an accuracy of ±0.1 mm.
2. Digital Molding and Bending Process
Laser Cutting
The positioning accuracy of laser cutting reaches ±0.03 mm.
Specialized CNC Sheet - forming Equipment
Equipped with customized molds, the specialized CNC sheet - forming equipment ensures excellent straightness and flatness of the formed sheets.
Bending Process
We are equipped with an AMADA HG - 1003ATC bending center featuring real - time laser detection. The bending data for each specification is stored in the data center, thus ensuring the consistency of products.
3. Robot - assisted Welding Technology System
We have established robot - assisted welding workstations. For each product, different programs are employed for fully - digital welding to ensure the firmness of welds and the consistency among batch - produced items. The laser welding process is adopted, with a penetration depth of 3.2 mm. All welds are subjected to X - ray flaw detection.
4. Surface Treatment System
Anodizing Line
We utilize a seven - step anodizing line with a film thickness of 20 - 25 μm.
Salt - spray Test
The salt - spray test duration meets the 800 - hour standard.
Optional Surface Treatment Processes
Optional surface treatment processes include hard anodizing (HV≥400), fluorocarbon spraying, and electrostatic powder spraying. There are a variety of color options available for the products.
II. Full - Process Quality Management System
1. Incoming Material Control
Material Composition Analysis
Material composition analysis is carried out using a spectrometer, with an error of ≤0.01%.
Sampling Inspection of Imported Seals
Batch sampling inspection of imported seals is conducted, with a leakage rate of < 0.5 cc/min.
Salt - spray Test for Hardware Parts
Hardware parts are subjected to a salt - spray test for a duration of ≥72 hours.
2. Process Monitoring
Real - time data collection is implemented at 16 SPC (Statistical Process Control) control points. During the assembly of hinges and locks, professional quality inspectors conduct a comprehensive inspection of the gaps, tactile feel, and riveting conditions of the assembled parts.
3. Finished Product Inspection
Dynamic Load Test
The dynamic load test is carried out at 150% of the rated load. The product can bear a load of over 100 kilograms.
Vibration Test
The vibration test is performed in accordance with the ISTA 3A standard to ensure that no abnormal noise is generated due to riveting loosening during long - term use of the product and to prevent any impact on the opening and closing of the hinge.
4. Traceability System
Each product is assigned a unique identity through laser marking. Video archiving of key processes is carried out, with a retention period of 5 years. Quality data is certified using blockchain technology.
Through the vertically integrated intelligent manufacturing system, we have achieved a product defect rate of ≤200 PPM and maintained dimensional tolerances within the IT10 grade, thereby providing truly reliable mobile storage solutions for outdoor users worldwide.
