Coated Process of Aluminum Foil
6. Manufacturing Process of 140μm 3003 H24 Coated Aluminum Foil
6.1 Alloy Casting and Rolling
Production begins with aluminum ingots and controlled alloying additions. Manganese gives 3003 its improved strength and corrosion resistance.
After casting and homogenization, the material passes through hot rolling and cold rolling to approach the target gauge.

Before coating, the foil surface needs proper cleaning and pretreatment.
તેલ અવશેષો, oxide instability, ધૂળ, or moisture can weaken coating adhesion.
6.4 Coating Application and Curing
The coating may be applied by roller coating, સચોટ, or lamination-related processes.
After application, controlled drying and curing create the required adhesion, લવચીકતા, અને રાસાયણિક પ્રતિકાર.
6.5 સ્લિટિંગ, સ્તરીકરણ, and Rewinding
The coated foil is slit to the required width. Accurate slitting reduces burrs, edge cracks, and winding defects.
Stable tension control protects surface quality and prevents telescoping or coil deformation.
6.6 ગુણવત્તા નિરીક્ષણ
Inspection usually covers thickness, પહોળાઈ, સપાટતા, સપાટીની ખામી, coating adhesion, પિનહોલ્સ, યાંત્રિક ગુણધર્મો, and packaging quality.
