How to Ensure Surface Quality of Polished Aluminum Strips

The polished aluminum strips is widely used for cosmetics packaging, high-end gift boxes, mobile phones, computer shell,etc. Its unique properties are very in line with the needs of industrial production, such as uniform hardness, good bending performance, corrosion resistance, high temperature resistance and other advantages.

It is processed by rolling, grinding and other methods to make the surface of the aluminum flat strip show a mirror effect. To make aluminum mirror strip, the first is the choice of the aluminium coil. The aluminum coil quality will directly affect the quality of the finished mirror aluminum material.

Then, clean and polish the selected aluminum coil In this process, you must be very careful when grinding, which is also a very important part. It is much simpler to wrap the film in separate rolls. Just pay attention to the viscosity of the protective film and whether there is glue left after tearing off the protective film.

The surface scratch is a main quality problem of the mirror finish aluminum strips. If there are metal particles or aluminum scraps on the non-woven fabric on the equipment during the production process, and the surface is scratched when the aluminum strip is cut properly. This kind of scratch is that the scratch position is uniform. At this time, it is necessary to stop the machine to clean the slitting equipment and replace the non-woven fabric.

The aluminum reflective tape is also likely to be scratched during the rewinding and unwinding process. It is generally caused by the aging of the equipment and the asynchronous electrical supporting equipment. At this time, the electrical system of the equipment needs to be replaced.

It may be also because of the raw material. It is the scratches in the production process of the aluminum strip raw materials, which has nothing to do with the slitting equipment, and can be solved by replacing the raw aluminum coils. Haomei Aluminum can fully avoid the above mentioned problems.
