Generally speaking, industrial aluminum profiles refer to all aluminum profiles except for building doors and windows, curtain walls, indoor and outdoor decorations, and building structures. So there are strict requirements for quality, what are the reasons for surface damage of industrial aluminum profiles?
1. There are impurities attached to the surface of the ingot or segregation of the ingot components. There are a certain number of hard metal particles inside the ingot. During the extrusion process, when the metal flows through the working strip, these segregation floats or hard metal particles adhere to the surface of the working strip or cause damage to the working strip, causing scratches on the surface of the profile;
2. When the fork rod transports the profile from the discharge track to the swing bed, the formed material collides due to excessive speed;
3. There are debris on the mold cavity or work strip, and the hardness of the mold work strip is low, which causes the surface of the work strip to be injured and scratched during extrusion, resulting in profiles being scratched;
4. Scratches caused by manually dragging industrial aluminum profiles on a bed;
5. There are exposed metal or graphite strips with hard inclusions on the discharge track or bed, which can cause scratches on the surface of industrial aluminum profiles when in contact with the profiles;
6. Damage caused by friction or compression between profiles during transportation.
Qualified industrial aluminum profiles should have a smooth and beautiful surface, but with the increasing demand for industrial aluminum profiles by enterprises, many aluminum profile manufacturers with uneven technical levels continue to emerge. Many industrial aluminum profile processing manufacturers, due to their own lack of strength and production and operation, produce aluminum alloy profiles with continuous surface scratches, scratches, and bumps, resulting in surface damage to industrial aluminum profiles. So it is necessary to choose a strong industrial aluminum profile production and processing manufacturer for cooperation!

What are the advantages of choosing insulated aluminum alloy profile windows?
What are the advantages of choosing insulated aluminum alloy profile windows? Compared with the standardized aluminum door and window architecture, insulated aluminum alloy profile windows have many advantages. For example, insulated aluminum alloy profiles will be integrated with reinforced acrylic resin rods for thermal insulation and frost resistance. Insulated aluminum alloy profiles and reinforced acrylic resin rods can generate insulation system software to block outdoor heat, cold, and noise. Ensure warmth in winter and coolness in summer, and provide a very comfortable natural environment for building construction.
