Reasons and Solutions for Surface Damage of Led Aluminum Profile Shell

Reasons and solutions for surface damage of led aluminum profile shell
Now aluminum materials are more and more widely used in our lives, and the price of aluminum shell materials is moderate, and the sales in the market are very good. Aluminum profile shells and aluminum alloys are the most widely used metals after steel materials. Structural material, compared to steel material. The main advantages of aluminum are light weight and corrosion resistance. Aluminum is only about one-third the density of steel.
Aluminum and aluminum alloys have many obvious advantages as engineering materials; such as good heat transfer and electrical conductivity, strong shock absorption and light reflection, etc., aluminum and aluminum alloys also have excellent formability and weldability; the following The reasons for the surface damage of the aluminum profile shell and the reasons for the surface damage of the aluminum profile shell summarized by Hongfa Shunda are as follows:
1. There is stray or segregation of the ingot on the surface of the ingot. When a large amount of segregation occurs on the surface of the ingot, and the uniform treatment or homogenization treatment effect is not good, there are a certain number of hard metal particles in the ingot. When the metal flows through the extrusion process. When working in the working area, these separated floats or hard metal particles adhere to the surface of the working belt, or cause damage to the working belt, which eventually leads to scratches on the surface of the profile.
2. When the fork rod sends the profile from the discharge trajectory to the pendulum, the profile will be scratched due to the excessive speed.
3. There are hard inclusions in the exposed metal or graphite strips on the discharge channel or on the pendulum, which will cause surface scratches when in contact with the profile.
4. There are sundries on the mold cavity or working belt, and the hardness of the working belt is low, so that the surface of the working belt is damaged and scratched during the extrusion process.
Solution for surface damage of aluminum shell:
1. Strengthen the control of the quality of steel ingots.
2. During the production process, you should put it aside gently and try to avoid dragging or turning pages at will.
3. Use soft felt to separate the profile from the auxiliary tools to minimize the contact damage between the profile and the auxiliary tools.
4. Improve the maintenance quality of aluminum profile shell processing molds, regularly carry out mold nitriding, and strictly implement the nitriding process.
