What Are The Product Quality Discrimination Skills Of Industrial Aluminum Profile Manufacturers?

1. Look at the logo and surface quality

After first getting the products of industrial aluminum profile manufacturers, you should check the product standard code and production license number on the packaging. Then observe the quality of the surface to see if it is clean enough, and to see if there are cracks on the surface, skin or bubbles, etc. Good quality products are not allowed to have these defects. At the same time, industrial aluminum profile manufacturers reminded that they should also check the thickness of the oxide film, because this layer of film not only has a decorative role, but also plays a protective role, so you can use the instrument to detect.

2. Look at sealing quality

Because industrial aluminum profile manufacturers need to go through the oxidation process during the production of products, many voids will be formed on the surface at this time, and these voids need to be closed. Therefore, it is necessary to look at the quality of this aspect when selecting. Because if not handled properly, corrosion resistance will be affected. Therefore, a wide variety of industrial aluminum profile manufacturers often adopt the acid leaching method to conduct on-site inspections. After simple processing, specific conditions can be observed to identify the quality of sealing.

3. Look at corrosion resistance

If you want to know how the quality of an industrial travel manufacturer's product should also focus on its corrosion resistance, because it directly affects his service life. Industrial aluminum profile manufacturers introduce more effective inspection methods including copper accelerated acetate spray test and alkali drop test. The alkali drop test is to use a relative concentration of NaOH solution to drop onto the surface of the product under certain temperature conditions. Observing the corrosion and bubbling, you can get more reliable and accurate data for judgment.
