Burr is a problem often encountered in the processing of aluminum products. Once the burr is formed, it is difficult to remove it later. It not only affects the aesthetics of the processed aluminum product, but also affects its performance. Then, how do these burrs occur? What? What are the reasons for its appearance?

1. Process aluminum products under high temperature and high pressure. The aluminum profile deforms into a trumpet shape after being pressed. The cutting edge part contacts the profile to form sticky aluminum, and there are continuous "turning knobs" being brought out by the profile and adhered to the surface of the profile. On top, forming a "burr".

2. If the empty tool position of the mold is too shallow, the sticky aluminum will gradually increase, and the sticky aluminum gradually brought out by the profile will form "burrs".

3. The surface of the aluminum profile and internal impurities are accumulated in the dead zone of metal flow. During the processing, the impurities in the dead zone are constantly changing. The profile is pulled out, forming "burrs".

Industrial aluminum profile is our common frame profile, which is often used in the frame of anti-static workbench and assembly line. The anti-static workbench has high requirements for anti-static, and no static electricity should be allowed in any part. In this way, industrial aluminum profiles should be anti-static.
