Below is a clear and professional workflow description for a distribution box (electrical cabinet) production line,

1. Material Procurement & Quality Inspection

The production of a distribution box begins with strict material sourcing. All incoming steel sheets, profiles, and electrical components must pass rigorous quality inspections to ensure consistency, structural reliability, and compliance with industry standards. Any materials that fail to meet specifications are rejected immediately.

2. Material Cutting & CNC Processing

Based on engineering drawings and design specifications, raw materials are processed using automatic cutting machines and CNC fabrication equipment. This step ensures high-precision cutting, punching, and shaping of components needed for the electrical cabinet structure.

3. Welding & Assembly of Cabinet Structure

All cut parts are welded and assembled to form the main body of the distribution box. This stage requires skilled operation and strict quality control to eliminate welding defects, ensure structural stability, and improve the long-term durability of the enclosure.

4. Surface Treatment & Coating

To enhance corrosion resistance and overall appearance, the cabinet body undergoes professional surface treatment such as rust removal, sandblasting, phosphating, followed by powder coating or spray painting. This process significantly improves durability and environmental resistance.

5. Functional Testing & Final Quality Check

The finished distribution box must pass electrical performance tests, mechanical reliability checks, and appearance inspections. Only products that meet national and international safety standards are approved for packaging and delivery.
