Aluminium sheet foil mainly used in the food packaging, medicinal aluminum foil, battery packs and other areas have a good performance. In particular, with the development of aluminium coils/foils production process, medicinal aluminum foil with its excellent moisture resistance, barrier properties, chemical resistance, chemical stability, health, the proportion of applications rising, the appearance and quality requirements of the more. The higher the market outlook is very broad.
The thickness of household aluminum foil sheet is generally less than 0.2mm, its processing technology is more mature, but the process still have to pay attention.
The first to control the quality of materials, strict inspection of blanks.
Secondly, during the rolling process, the surface quality of the aluminum foil is controlled by controlling the cleaning and roughness of the roll, selecting the rolling oil, reducing the viscosity of the rolling oil and controlling the running speed of the machine.
In cutting process, to ensure that when cutting aluminum coil foil roll edges neat, falbala, such as quality problems.
Finally, in the annealing process, according to the performance requirements of the jumbo coil aluminum foil to control the annealing time and annealing temperature, to ensure clean oil.
