Description :

Prioritize structural rigidity through pressed ribs (h≤2mm for 1-3mm materials) to reinforce long panels.

Optimize bending sequences for simplified fabrication, avoiding complex 3D geometries by adopting modular welded/bolted assemblies.

Select appropriate stiffener profiles from standard tables to enhance load-bearing capacity while maintaining material efficiency.

For thin-gauge components (thickness <5% of length), implement edge-flanging techniques to counteract transverse bending weaknesses.

Ensure compliance with sheet metal DFM principles: minimize weld seams through unified bends,

standardize fastener positions (M4-M8 studs), and maintain ≥R1.5mm internal bend radii.

This approach balances manufacturability, weight reduction (15-20%)

Product Description:

Technical Overview of Optimized Metal Cabinet Design

This engineered cabinet system features an asymmetric hinge configuration with dual lower-mount positioning

(offset 15% from standard equidistant layout) to enhance vertical load distribution.

The hybrid welding approach combines:    welding cabinet                                       

  1. Internal Spot Welding:
    • 3mm staggered stitch welds (AWS D1.3 compliant)
    • 40% reduced thermal distortion vs continuous welding
  2. External Full-Penetration Welds:
    • GMAW process with ER70S-6 wire
    • 8mm reinforcement bead

Structural enhancements include:

  • Cold-rolled steel construction (1.5mm SPCC) with 250MPa yield strength
  • Reinforced corner gussets (2.5mm thickness transition)
  • Optimized weld sequence minimizing residual stress

The low-position hinge mounting (120° angular placement) achieves 35% improved moment resistance, supporting 150kg dynamic loads. Manufacturing process implements:

  • Fixture-based assembly ensuring ±0.8mm alignment tolerance
  • Post-weld stress relief (vibration aging treatment)
  • Zinc-rich primer coating (45μm DFT) with electrostatic powder topcoat

This design solution demonstrates 20% weight reduction compared to conventional symmetric hinge arrangements while maintaining EN 1090-2 structural compliance. Production utilizes modular tooling compatible with automated welding cells, achieving 18% faster cycle times versus traditional cabinet fabrication methods.
