Project Cases: Metal Box Body
This box is a metal three-proof storage and transportation box. With its high-strength structure and multiple protective designs, it has become a core tool for the storage and transportation of high-risk items and the protection of specialized equipment. It is widely used in scenarios with extremely high safety and durability requirements. Its production process mainly includes the following links:
1. Design and material preparation
Design stage: Detailed drawings are prepared based on usage requirements (such as size, load-bearing capacity, and protection level) to determine the sheet thickness (usually high-strength carbon steel) and structural details (such as the layout of the lock and handle).
Material procurement: Select cold-rolled steel plates that meet strength and anti-corrosion requirements, and conduct raw-material inspections (e.g., material composition and flatness testing).
2. Sheet metal processing
Cutting: Using CNC laser or plasma cutting, the steel plate is cut to the initial shape of each panel of the box (such as the bottom plate, side plate, and cover plate).
Bending forming: Using a CNC bending machine, the cut sheet is bent into a three-dimensional box structure (such as the 90° folding edge of the side plate and the sealing flanging of the cover plate).
Stamping processing: Stamping is performed on accessories such as locks and handles to form them, and at the same time, installation holes, lock holes, and other structures are stamped into the box panel.
3. Welding and assembly
Welding: Use argon arc or seam welding to assemble each panel into the main body of the box, ensuring proper sealing and weld seam strength. At the same time, weld the handle, lock, and other accessories.
Assembly and debugging: Assemble the hinges, sealing strips, and other components of the box body; test the opening and closing of the cover plate and the locking function of the lock; and ensure structural stability and protective performance.
4. Surface treatment
Deburring and grinding: Remove burrs and sharp edges produced by welding and stamping to ensure a smooth surface.
Anti-corrosion coating: Usually, the electrostatic powder coating process is used, with anti-rust coatings such as military green sprayed. After high-temperature curing, a uniform protective film forms, enhancing moisture-proofing, flame-retardant, and anti-corrosion capabilities.
5. Quality inspection
Dimensional inspection: Use measuring tools to check the length, width, and height of the box body, as well as the fit accuracy of each component.
Performance testing: Conduct air-tightness and impact-resistance tests (simulating vibration and collisions in transportation or field environments) to ensure the protective performance meets the standards.
6. Packaging and warehousing
Qualified products are cleaned and labeled, and then packaged in anti-collision packaging before being stored in the warehouse, completing the entire production process.
Before the bulk order is confirmed, we will produce a sample within 12 hours according to your requirements and send it to you. Only after your confirmation will we start mass production.
We understand the importance of completing projects on time. For this reason, relying on automated machines, we have achieved round-the-clock automated production, with a daily output of over 9,000. We can supply goods stably at any time and strictly adhere to the delivery date, providing a solid guarantee for your needs.
