There are many types of signs, and aluminum signs are only one of them. The manufacturing process is usually aluminum plate stamping, cutting, concave-convex and aluminum alloy die casting.
Common processes for making aluminum signs: high gloss, corrosion, oxidation, wire drawing, laser engraving, electroplating, spraying, reflection, luminous printing and other processes.
In the products of metal signs, the proportion of aluminum signs accounts for more than 90% of metal signs. For more than half a century, aluminum plates have been used to make signs for a long time, the main reason is that aluminum has the most decorative expression. Many surface decoration techniques can be applied and brought into play on aluminum materials, which is convenient to obtain colorful and various combinations of advanced decorative layers.
On the other hand, it is determined by a series of excellent properties of aluminum.
The advantages of using aluminum to make signs are as follows: 1. Light weight, aluminum density is 2.
Compared with copper and aluminum, 702gNaN3 is only 1/3 of It. The aluminum label will not increase the weight of the equipment, but also save money. 2.
Easy Processing, excellent ductility of aluminum, easy cutting, easy stamping, can meet the needs of special process signs. 3.
Good corrosion resistance, hard and dense oxide film can be formed on the surface of aluminum and its alloy. 4.
Good weather resistance, aluminum oxide film layer, many substances do not corrode it, and it will have excellent durability in the harsh environment of industrial areas and coastal areas. 5.
Without magnetism, aluminum is a non-magnetic body, and aluminum signs will not cause external interference to instruments and equipment. More advertising production in the advertising network. 6.
Rich in resources, the annual output of aluminum is second only to steel, ranking second in the world's total metal production.
The advantages of aluminum signage are not only many, but also the manufacturing process is becoming more and more mature.
