[Hottest] Reasons for the surface treatment of aluminum alloy processing How to reduce defective products in aluminum alloy processing

 The reason for the surface treatment of aluminum alloy processing? Today, Shenzhen Riqiya Electromechanical Co., Ltd. will bring you the “the reason for the surface treatment of aluminum alloy processing and how aluminum alloy processing can reduce defective products”, so that you can not only understand the previous aluminum alloy processing plants, Can have more knowledge of the industry!

[The hottest] Reasons for surface treatment in aluminum alloy processing How to reduce defective products in aluminum alloy processing

Aluminum is a light metal with silver white luster, and its corrosion resistance is as follows Two characteristics:

1. The higher the purity, the better the corrosion resistance. As we all know, pure aluminum reacts with oxygen in the air, and a thin, dense, natural layer is produced on the surface of aluminum. The oxide film is formed faster and thicker than other metal oxide films, thereby preventing the corrosion of harmful gases and moisture in the air and playing a protective role;

2, although the corrosion resistance of pure aluminum Good, but poor mechanical strength, which restricts the application of aluminum to a certain extent. Therefore, people add appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make various types of aluminum alloys. The mechanical strength of aluminum alloys High, so that the mechanical strength of aluminum is greatly improved, and the scope of application is greatly expanded. Although aluminum alloy has high mechanical strength, its corrosion resistance is worse than that of pure aluminum, so it may be corroded due to oxidation. This requires powder coating to protect aluminum alloy profiles. Aluminum alloys have been widely used in building doors, windows, curtain walls and other products for many years because of their small specific gravity, easy processing, and high mechanical strength. ,

So in the process of aluminum alloy processing, the surface treatment of aluminum is carried out. Aluminum profiles have many advantages such as high corrosion resistance, diversified colors, and good surface texture. The paint echoes the aluminum alloy, and the aluminum alloy is processed for surface treatment to create colorful buildings.

Many people have checked: How does the CNC machining machine work? How does CNC process molds?

In the current situation, the demand for industrial aluminum profiles is increasing, whether it is automobiles, mechanical protection, and railways. This naturally brings up the dual problems of cost and resource utilization, so how to improve the finished products of industrial aluminum profiles Rate has become a top priority, and there are many measures to improve productivity. This article mainly talks about two measures that are relatively more specific and practical.

1. Advanced equipment and high-quality workers are the prerequisites for increasing output.

For increasing the output of extrusion products, advanced equipment, high-quality workers, Modern scientific management plays a vital role. Among the more than 2500 industrial aluminum extrusion presses in our country, only about 25 are up to the international level, or about 1%. my country's aluminum extrusion industry is in the stage of structural adjustment, and low-level duplication should be avoided. Introducing and constructing, it is better to transform the existing industrial aluminum extrusion press with value into modern high-level industrial aluminum extrusion press.

2. The relationship between temperature control and increase in output

Generally, if there is no unscheduled downtime, the maximum output is mainly determined by the extrusion speed, and the latter is subject to processing How to reduce defective products in aluminum alloy processing is based on four factors, three of which are fixed and the other is variable. The first factor is the extrusion force of the industrial aluminum profile extruder. The larger extrusion force can be smoothly extruded when the ingot temperature is low; the second factor is the die design, the metal and the die wall during extrusion Friction can usually increase the temperature of the passing aluminum alloy by 35～62℃; the third factor is the characteristics of the alloy being extruded, which is an uncontrollable factor that limits the extrusion speed. The exit temperature of the profile should generally not exceed 540℃, otherwise , The surface quality of the material will be reduced, the mold marks will be significantly heavier, and even aluminum sticking, gravure, micro cracks, tearing, etc. will appear. The last factor is temperature and its degree of control.
