Nowadays, many industries will apply aluminum profile to this product. The reason why industrial aluminum profile will become an indispensable product in many fields is closely related to its advantages in quality and performance. At the same time, it is precisely because of the expanding demand for industrial aluminum profiles in the market that there are more and more manufacturers producing aluminum profiles on the market. However, there will be some competition among the more manufacturers, and many aluminum profile manufacturers will be eliminated!

1. Compared with other industrial products, the difference of aluminum profile industry is still relatively small, so the market competition of industrial aluminum profiles in the future is still cost competition;

2. The scale of industrial aluminum profile production and the development trend of horizontal and vertical integration of the industry are obviously accelerated, and some fast-growing enterprises will be the main force of the market;

3, people will pay more attention to the scale, brand, technology and service of the integrated enterprise comprehensive strength competition;

4. China's industrial aluminum profile market will become more and more common, especially in some coastal areas. At present, some large enterprises have developed overseas markets. The long-term development of an enterprise should focus on the longer term, and should not just focus on some small profits now.

Brittleness of aluminum profiles is fully reflected in the mechanical and physical properties of products.

Nowadays, many industries are inseparable from the application of aluminum profiles, so in order to ensure the application effect of aluminum profiles, it is necessary to buy high-quality aluminum profiles. Because inferior industrial aluminum profiles will bring many troubles to enterprises, such as brittle aluminum profiles. Brittleness of industrial aluminum profiles will affect the production of enterprises more or less in terms of cross-sectional appearance and other aspects, and the brittleness of aluminum profiles is fully reflected in the mechanical and physical properties of products.

1. Unreasonable formula and mixing process:

1. Too much filler;

2. Type and quantity of impact modifier;

3. Too much or too little stabilizer;

4. Excessive amount of external lubricant;

5. The sequence of hot mixing, temperature setting and curing time also have decisive factors on the properties of profiles.

Second, the extrusion process is unreasonable:

1. Excessive or insufficient plasticization of materials;

2. Insufficient pressure on the nose;

3. The low molecular components in the product are not discharged;

4, screw torque is too low;

5. The traction speed does not match the extrusion speed.

Third, the mold design is unreasonable:

1. The design of die section is unreasonable, especially the distribution of internal ribs and the treatment of interface angle. This will lead to the phenomenon of stress concentration, and we need to improve the design and eliminate the right angle and acute angle at the interface.

2. For the performance degradation caused by poor confluence of shunt ribs, it is necessary to appropriately increase the length of the junction between ribs and outer surface, ribs and ribs, or increase the compression ratio to solve it.

3. Uneven discharge of die results in different thickness of profile wall or inconsistent density. Industrial aluminum alloy profile this also caused the difference in mechanical properties between the two sides of the profile. In our experiments, sometimes one side of the cold stamping is qualified and the other side is unqualified, which just proves this point.
