From Steel Sheets to Trusted Assistants: Unveiling the Production Process of Steel Office Filing Cabinets

Steel office filing cabinets, indispensable as "storage experts" in modern office environments, are highly favored for their durability and space efficiency. But have you ever wondered how these seemingly simple metal cabinets are transformed from steel sheets? Today, let’s step into the production workshop of steel office filing cabinets and uncover the process!

1. Raw Material Preparation:

• Steel Sheet Selection: Cold-rolled steel sheets are primarily used for manufacturing steel filing cabinets due to their smooth surface, uniform thickness, and excellent strength and plasticity. Depending on the load-bearing requirements of the cabinet, steel sheets of different thicknesses, such as 0.6mm or 0.7mm, are selected.

• Surface Treatment: To prevent rust and extend the cabinet's lifespan, the steel sheets undergo surface treatment. Common methods include phosphating and electrostatic spraying. Phosphating enhances the steel's rust resistance and coating adhesion, while electrostatic spraying provides the cabinet with a colorful "coat," making it more aesthetically pleasing.

2. Sheet Metal Processing:

• Cutting: Large steel sheets are cut into the required components, such as side panels, bottom panels, and door panels, using a shearing machine.

• Punching: A punch press and molds are used to create various shaped holes in the steel sheets, such as lock holes, handle holes, and ventilation holes.

• Bending: A bending machine shapes the steel sheets into the desired forms, such as folding side panels into right angles or adding curves to door panels.

3. Welding and Assembly:

• Spot Welding: A spot welding machine joins the components together, such as welding side panels, bottom panels, and top panels into the cabinet frame.

• CO2 Protective Welding: For areas requiring higher strength, CO2 protective welding is used, such as for welding drawer slides and reinforcing ribs.

4. Surface Treatment:

• Pre-treatment: The welded cabinet body undergoes degreasing, derusting, and phosphating to prepare for the subsequent spraying process.

• Electrostatic Spraying: Powder coatings are electrostatically applied to the cabinet surface and then cured at high temperatures to form a uniform and durable coating.

5. Assembly and Debugging:

• Installing Accessories: Accessories such as locks, handles, slides, and partitions are installed onto the cabinet body.

• Testing and Debugging: The filing cabinet undergoes opening/closing tests and load-bearing tests to ensure proper functionality.

6. Packaging and Storage:

• Cleaning and Packaging: The finished cabinets are cleaned and protected with packaging materials to prevent damage during transportation.

• Storage and Dispatch: The packaged cabinets are stored in the warehouse, ready for shipment.

Conclusion:

The seemingly simple steel office filing cabinet involves numerous processes and technologies in its production. From steel sheets to practical office furniture, each step embodies the wisdom and hard work of skilled craftsmen. Through this article, we hope you’ve gained a deeper understanding of the production process of steel office filing cabinets. When selecting and using filing cabinets, we encourage you to pay more attention to their quality and craftsmanship.
