Fabrication Excellence
Forming & Welding:
Deep Drawing: Use 1/2H or 3/4H tempers for complex shapes | Apply PTFE-coated dies
Welding: ER308L filler for critical joints | Limit heat input to ≤1.5 kJ/mm to prevent Mn segregation
Surface Enhancement:
PVD coating for scratch-resistant gold/black finishes | Electropolishing for hygienic surfaces
Global Proof of Pragmatic Performance
IKEA Supplier: “202 strips in kitchen shelving systems showed zero rust after 5 years in 85% humidity.”
Tesla Subcontractor: “EV interior trims passed 1.000-hour UV aging tests without color fading.”
McDonald’s Asia: “Food tray liners survived 200.000+ dishwasher cycles with minimal wear.”
