Reasons and measures for orange peel on the surface of aluminum profiles

Update time : 2022-09-30 18:56:09

The orange peel produced by the surface treatment of aluminum profiles is a common and difficult leveling problem in the coating process. There are many influencing factors. The orange peel-like surface can be said to have a greater impact on the appearance and decoration of aluminum profile products. Then let's learn about the causes and solutions of orange peel during the surface treatment of aluminum profiles.

Causes of orange peel defects on the surface of aluminum profiles:

Generally, the reason for the orange peel defect on the surface of the aluminum profile is that the stretching amount of the aluminum profile is too large. Generally speaking, the thicker the wall thickness, the shorter the length of the profile. In order to ensure the straightness of the profile and prevent twisting, orange peel is more likely to occur when the amount of stretching is artificially increased.

Solutions for orange peel defects on the surface of aluminum profiles:

1. Strengthen the mold repair for the aluminum profiles that are easy to bend and twist, and control the straightness of the aluminum profiles;

2. Increase the traction force when the extrusion of the aluminum profile is still hot, and take corrective measures such as topping and pressing on the hot profile on the discharge table (pay attention to preventing the deformation of the profile);

3. Control the elongation rate of the aluminum profiles of the aluminum profile manufacturers. In order to ensure the surface quality while taking into account the straightness, the bending degree during stretching is strictly controlled within the upper limit required by the customer;

4. Control the elongation rate of the aluminum profile. In order to ensure the straightness and take into account the surface quality, cut off more of the deformed part at the two ends of the profile stretching and the stop mark.

Spraying cleaning method of industrial aluminum profiles is widely used, because of complex equipment, high process requirements, poor cleaning effect, then how to better do spray cleaning of industrial aluminum profiles?

Aluminum extrusion profile six places are required during the stretching process

The aluminum extrusion profile must be cooled to below 50 degrees before stretching. If the temperature is too high, stretching will not only burn the human body, the hair belt, but also expose absolute waste products such as bending, twisting, and poor performance before and after aging, because the stress in the aluminum alloy profile can not be completely eliminated.

Appearance quality of curtain wall aluminum profile: the surface of anodic oxide film is not allowed to have electrical burns, oxide film falling off and other defects; Electrophoretic, powder, fluorocarbon profile paint film should be uniform, neat, smooth, do not allow wrinkles, cracks, bubbles, flow signs, inclusions and paint film fall off and other defects, but allow local film within 80 mm at the end of the profile.
