Six Core Intelligent Manufacturing Processes to Create Industrial-Grade Sheet Metal Products


1. Intelligent Material Cutting and Forming

- Utilizing a laser cutting system to achieve precision cutting of ±0.1mm.

- Fully automated CNC bending center with bending precision of ±0.15°.

- Thick plate processing employs 2500T hydraulic stamping equipment to ensure the overall strength of structural components.


2. Precision Welding Technology

- Robot workstation equipped with ABB six-axis welding robot to achieve weld seam uniformity of ≤0.3mm.

- Introduction of TIG pulsed argon arc welding technology and laser welding technology to effectively control thermal deformation, resulting in full and aesthetically pleasing weld seams.

- Key load-bearing areas can be designed to use reinforcement ribs with secondary welding technology.


3. Fully Automated Surface Treatment

- Combining fully automated polishing with manual polishing by professionals. Infrared calibration is performed on the straightness and flatness of various edges of the cabinets.

- Ten-stage phosphating treatment line ensures compliance with 72-hour salt spray testing.

- AkzoNobel electrostatic powder coating system ensures membrane thickness uniformity of ±5μm, baking above 200℃, and surface adhesion of the coating is tested to guarantee long-term corrosion resistance and wear resistance.

- Optional DACROMET anti-corrosion process, enhancing salt spray resistance to 1000 hours.


4. Zero Defect Management: Four-Dimensional Quality Control System


1. Raw Material Traceability Management

- Quality cold-rolled sheets (SPCC) undergo warehouse inspection, generating material analysis reports and physical property test reports.

- Coating thickness detection equipment (XRF method) ensures coating thickness ≥60g/m².

- Bidirectional traceability of material certification documents and physical batches.


2. Process Quality Monitoring

- Laser online detection system monitors key installation dimensions and hole locations in real-time.

- Welding quality X-ray inspection sampling ratio of ≥20%.

- Coordinate measuring machine (CMM) performs full dimension sampling.


3. Finished Product Comprehensive Testing

- Vibration testing table simulates operational vibrations from 5-500Hz.

- Load testing uses a safety factor of 1.5 for loading.

- Ground resistance tester ensures contact resistance ≤0.1Ω.


4. Continuous Improvement Mechanism

- MES system collects over 200 quality data points.

- Monthly QCC quality control circle meetings.


5. Core Advantages: Multi-Dimensional Assurance of Professional Manufacturing Capability


1. Customized Production Capability

- Supports ODM/OEM services from drawings to finished products.

- Rapid prototype production cycle of 7-15 working days.

- Meets international certification requirements such as UL, CE, RoHS.


2. Capacity Assurance System

- Fully automated production line with a daily output capacity of 3000 standard parts.

- Intelligent warehousing system enables rapid shipping.

- Emergency capacity reserve mechanism ensures timely order delivery.
