The electrical box production line is a set of automated equipment designed to process metal coils (such as galvanized steel, cold-rolled steel) into complete electrical boxes. It integrates multiple processes, realizing full automation from raw materials to finished products, which greatly improves production efficiency, ensures product consistency, and reduces labor costs, making it an ideal production solution for electrical box manufacturers worldwide.

Core Production Process

A standard automated production line usually includes the following processes, which are fully automated and require minimal manual intervention:

1. Uncoiling & Leveling: The metal coil is uncoiled and leveled to eliminate internal stress and ensure the flatness of the sheet, laying a solid foundation for subsequent processing.

2. Servo Feeding: High-precision servo motors control the accurate feeding of the sheet, with stable feeding speed and high positioning accuracy, ensuring the consistency of processing dimensions.

3. Pre-punching & Notching: Automatic punching of mounting holes, heat dissipation holes and corner notches on the sheet according to the design requirements, with neat holes and precise positions.

4. Roll Forming: The sheet is continuously rolled into the outline of the electrical box through multiple sets of forming rolls, with smooth forming and consistent cross-sectional shape.

5. Cutting to Length: The formed profile is cut to the set size according to the specifications of the electrical box, with high cutting precision and no burrs.

6. Bending & Forming: The cut profiles are automatically folded into the electrical box frame, with accurate bending angle and firm structure.

7. Post-processing: Including welding (to enhance the firmness of the box), surface spraying (anti-corrosion, anti-rust, and improving appearance), electrical component installation and final performance testing, ensuring that each finished product meets the quality standards.

Main Technical Parameters

• Applicable Material: Cold-rolled steel, galvanized steel, stainless steel

• Material Thickness: 1.0–2.0 mm

• Forming Speed: 0–13 m/min (adjustable according to production needs)

• Control System: PLC + Touch Screen HMI (easy to operate, convenient for parameter setting and fault diagnosis)

• Production Efficiency: About 2–3 boxes per minute (varies slightly according to box specifications)

• Dimensional Accuracy: ±0.5 mm (ensuring good interchangeability of products)

Core Features & Advantages

• High Automation: The whole process from raw material uncoiling to finished product testing is fully automated, requiring only 1–2 operators for supervision and operation, which greatly reduces labor intensity and labor costs.

• High Precision: Adopting numerical control technology and high-precision servo system, the processing dimensions are accurate, the product consistency is good, and it can meet the strict quality requirements of different markets.

• Flexible Production: It can quickly switch parameters to produce electrical boxes of different specifications (length, width, height), adapting to the diversified production needs of manufacturers, and improving production flexibility and market adaptability.

• Cost Optimization: While improving production efficiency, it reduces material waste and labor costs, shortens the production cycle, and helps manufacturers improve market competitiveness with cost advantages.

• Stable Performance: The equipment is made of high-quality components, with stable operation, low failure rate, easy maintenance, and long service life, ensuring continuous and stable production.
