Production process of 28 aluminum cover

The production process of 28 aluminum covers mainly includes the following steps:

First of all, select excellent aluminum alloy materials as raw materials, after cutting, bending and other pretreatment, into the press forming link. In this 1 section, the aluminum alloy material is pressed into a circular aluminum cover with a diameter of 28mm through a mold.

Next, the aluminum cover is subjected to surface treatment, such as bright grinding, to improve its appearance quality and corrosion resistance. Subsequently, according to customer needs for printing, the pattern or text is printed on the surface of the aluminum cover, and drying and curing treatment is carried out to ensure that the printed pattern and text will not fall off or fade.

In addition, the quality inspection of the aluminum cover, including appearance inspection, size inspection, coating thickness inspection, etc., to ensure that each aluminum cover meets the quality standards. Only the aluminum cover that has passed all the quality inspection links will be recognized as a qualified product and used to package various products.

The entire production process requires meticulous operation and strict quality control to ensure product quality and performance.
