Breakthroughs in 5754 aluminum coil stamping technology driven by the trend toward lightweighting in

Optimized material pre-treatment: Laser cutting and constant temperature storage (humidity <60%, temperature 15-25°C) ensure surface defects on 5754 aluminum coils with a thickness tolerance of ±0.05mm, laying the foundation for high-precision stamping.

Multi-step progressive forming: A combined pre-bending, stretching, and shaping process, combined with a die design with corner radius R ≥ 0.3mm, effectively controls springback and improves the precision of complex curved surfaces.

Intelligent temperature control and post-processing: Laser-assisted heating of localized areas, combined with micro-arc oxidation surface treatment, ensures that 5754 aluminum coil stampings achieve both high strength (tensile strength ≥ 145MPa) and corrosion resistance.
