Brushed aluminum sheet metal process

0 Comment

The brushed process of the brushed aluminum sheet metal 1100 3003 5052 6061 is a new type of surface treatment process, mainly using aluminum as the base material, and the texture are pulling out on the surface by using a brush wheel, a wire brush belt or a nylon ring belt, and the brushed process is made of various chemical treatments such as pressed and roll coating, the final brushed aluminum product has bright, uniform surface and strong sense of fashion.

The brush process is to be done after the stamping, and the brush can be made into several lines such as straight lines, chaotic lines, threads, corrugations and swirls according to the decorative needs of the brushed aluminum sheet.

1, straight line brush refers to the processing of straight lines on the surface of aluminum sheets by mechanical friction. It has the dual function of brushing the surface scratches and decorating the surface of the aluminum sheet metal. Straight line brush has two types: continuous thread and intermittent thread.

2, chaotic brush is a kind of irregular, no obvious grain matt brush pattern obtained by moving the aluminum sheet back and forth and left and right under the high-speed running copper wire brush. This processing has high requirements on the surface of aluminum sheet alloy.

3, the corrugation is generally made on the brush or the rubbing machine. Using the axial movement of the upper set of grinding rolls, brush the surface of the aluminum alloy sheet to obtain wave pattern.

4, the rotary pattern is also called optical rotation, which is a kind of brush thread obtained by rotating or polishing the surface of aluminum sheet by using cylindrical felt or grinding stone nylon wheel on the drill bed. It is mostly used for the decorative processing of circular signs and small decorative dials.

5, the thread is to use a small motor with a circular felt on the shaft, using the rotation of the felt and the linear movement of the carriage, a thread of uniform width is spun on the surface of the brushed aluminum sheet metal.
