In recent years, the market demand for aluminum is more and more big, a lot of new aluminum manufacturers also appeared on the market, but because the technology does not pass, no production experience, the production of aluminum unqualified product quality, resulting in aluminum brittle, so what is the cause of brittle aluminum?
1, aluminum manufacturers for shunt performance due to reinforcement caused by poor confluence decline should be appropriate to increase the rib and the outer surface, tendon and tendon at the confluence of the length, or increase the compression ratio, die pressure change can be adjusted by changing the flow resistance of the die head straight length.
2, the cooling rate of the mold and the cooling water temperature often fail to attract enough attention. The role of cooling water is to cool the profile chain in time and achieve the purpose.
3, the section design of the die is unreasonable, especially the treatment of the distribution of the inner reinforcement and the angle of the interface. This will cause the phenomenon of stress concentration. We need to improve the design and eliminate the right angle and sharp angle at the interface.
4, the die material is uneven, resulting in inconsistent thickness of the profile wall, or inconsistency of density, which results in the difference in mechanical properties between the two surfaces.
5, the pressure of the die head is insufficient and the pressure of the die head is directly determined by the compression ratio of the die, especially the length of the die flat section. The compression ratio of the die head is too small or the straight section is too short will cause the aluminum plate products to be not dense and affect the physical properties.
The above is the knowledge that Xiao Bian tells you. We have strict working attitude and skilled working skills. We will ensure that tasks are done accurately and efficiently.
