Chassis and Cabinet Sheet Metal Fabrication Process:
1. Basic Process Flow
--Design Phase: Use software such as SolidWorks/AutoCAD to complete 3D modeling. Consider factors such as heat dissipation hole locations and load-bearing structures.
--Cutting Process: Laser cutting achieves an accuracy of ±0.1mm. CNC punching is suitable for batch hole processing, and shearing machines are used for straight-line cutting.
--Bending: A 200-ton servo press brake can process 6mm steel plates. Pay attention to the bending sequence (large angles first, then small angles) and mold selection (notch width ≥ 6 times the plate thickness).
--Welding and Assembly: Argon arc welding is used for stainless steel, and CO₂ shielded welding is used for carbon steel. Post-weld polishing is required.
--Surface Treatment: Powder coating (30-80μm film thickness) or brushed/mirror polishing. Must pass a 1000-hour salt spray test.
2. Key Process Highlights
--Precision Control: Coordinate measuring machines check dimensional tolerances (±0.05mm), and X-ray inspections check weld quality.
--Material Selection: 304 stainless steel (1.0-1.5mm) for food equipment, galvanized steel (0.6-1.0mm) for cost-effective products.
Special Processes:
--Laser welding technology achieves 1500MPa high-strength structural components.
--CNC dispensing replaces traditional sealing strips, improving waterproof and dustproof performance.
--UV flatbed printing enables personalized logo design.
3. Quality Inspection Standards
Dimensional Inspection: Key hole accuracy ±0.05mm, flatness ≤0.5mm/m
Strength Testing: Load-bearing test must reach 1.5 times the design load
Environmental Testing: IP54 protection rating (dust and water resistance)
Surface Inspection: Color difference ΔE ≤ 1.5, adhesion test (cross-cut method)
4. Typical Application Cases
Server Cabinet: 1.2mm cold-rolled steel, bent and powder-coated
Power Control Cabinet: 2.0mm galvanized steel, welded, must pass EMC testing
Medical Equipment Cabinet: 304 stainless steel, laser-cut, mirror-polished
