Coated Process of Aluminum Foil
6. Manufacturing Process of 140μm 3003 H24 ແຜ່ນອາລູມິນຽມເຄືອບ
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.
6.2 Temper Control to H24
The mill controls cold reduction and annealing to achieve H24 temper.
This step matters because excessive hardness may reduce formability, while insufficient hardness may cause poor shape retention.
6.3 Surface Pretreatment
Before coating, the foil surface needs proper cleaning and pretreatment.
ນ້ຳມັນຕົກຄ້າງ, oxide instability, ຂີ້ຝຸ່ນ, or moisture can weaken coating adhesion.
6.4 Coating Application and Curing
The coating may be applied by roller coating, ຂະເຫມັນັ, or lamination-related processes.
After application, controlled drying and curing create the required adhesion, ຄວາມຍືດຫຍຸ່ນ, ແລະການຕໍ່ຕ້ານສານເຄມີ.
6.5 ຕັດ, ການປັບລະດັບ, 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 ການກວດກາຄຸນນະພາບ
Inspection usually covers thickness, ຄວາມກວ້າງ, ຮາບພຽງ, ຂໍ້ບົກພ່ອງດ້ານ, coating adhesion, Pinholes, ຄຸນສົມບັດກົນຈັກ, and packaging quality.
