• Sanya sarufa : Sarufan cut must be smooth and free of nicks or burrs—stress-concentrating flaws that accelerate crack propagation
• Gudanar da springback : Don 30° final bend, form 50°–70° initially and allow 48 hours for stress relaxation before trimming
• Daidaiton amfani : Avoid cold line bending for UV-coated, safety-critical, or high-impact applications—residual stress remains locked in and compromises long-term performance

Always validate parameters on scrap material before committing to production.
