Causes And Solutions For Scratching The Surface Of Aluminum Profiles

Jan. 19, 2019

Custom  Aluminum Hardware Accessories surface: causes of scratches, abrasions, and scratches:

1. Impurities attached to the surface of the ingot

2. Segregation of ingot composition, a large amount of segregation float on the surface

3. When the ingot is not homogenized or homogenized, the ingot contains a certain amount of hard metal particles. When the metal flows through the working belt during extrusion, these segregation floats or hard metal particles adhere to the surface of the work belt or cause damage to the work belt, eventually causing scratches on the surface of the profile.

4. There are debris in the mold cavity or working belt, and the hardness of the working belt of the mold is low, so that the surface of the working belt is injured during the extrusion and the profile is scratched;

5. There are bare metal or graphite strips in the discharge track or pendulum. Scratching the surface of the profile when it comes into contact with the profile;

5. The friction or extrusion between the profiles during transportation causes damage.

1. Strictly control the quality of the ingot chemical composition;

2, improve the quality of mold repair,

3. Improve mold manufacturing precision and regular nitriding of the mold and strictly implement the nitriding process parameters;

4. Separate the profile from the auxiliary tool with soft felt and plastic strip. Minimize contact damage between profiles and accessories;

5, in the production should be lightly handled, try to avoid dragging or flipping Custom Aluminum Parts;

6. Place the profiles reasonably in the material frame to avoid rubbing each other.
