Hongkong credit aluminum teaches you how to deal with black spots in the production process of furniture aluminum:


Due to the insufficient air cooling at the outlet of the extruder, the aluminum material of furniture contacts the swing bed at a higher temperature. The cooling speed of the contact part is different from that of other door and window aluminum profiles, with coarse magnesium phase precipitation. After anodizing, the part turns black gray. This phenomenon should be strictly prevented in the production process to reduce unnecessary losses. The main solutions are as follows:

1. Strengthen the air cooling strength, avoid too small interval of profiles on the swing bed, and ensure the temperature gradient of air cooling;

2. The factory with conditions shall adopt the method of combination of aluminum material of fog furniture and air cooling to completely eliminate black spots.
