铝板表面划伤的原因：

Reasons for scratches on the surface of aluminum plates:

划伤，擦伤，碰伤。

Scratches, abrasions, bumps.

合金铝板

Alloy aluminum plate

1.合金铝板在生产过程中铝流经工作带时，这些偏析浮出物或坚硬的工业铝型材颗粒附着在工作带表面或损坏工作带，最终划伤型材表面。

During the production process of aluminum alloy plates, when aluminum flows through the working strip, these segregation floats or hard industrial aluminum profile particles adhere to the surface of the working strip or damage the working strip, ultimately scratching the surface of the profile.

2.合金铝板模具或工作带上有杂物，模具工作带硬度低，挤压工作带表面时会划伤铝板。

2. There are debris on the alloy aluminum plate mold or work strip, and the hardness of the mold work strip is low. When squeezing the surface of the work strip, it will scratch the aluminum plate.

3.出料轨道或摆床上有裸露的铝或石墨条内有硬夹杂物，当与铝接触时，会划伤合金铝板表面。

3. There are hard inclusions inside exposed aluminum or graphite strips on the discharge track or bed, which can scratch the surface of the alloy aluminum plate when in contact with aluminum.

4.在摆床上人工拖动合金铝板造成擦伤。

4. Scratches caused by manually dragging alloy aluminum plates on the bed.

5.合金铝板在运输过程中相互摩擦或挤压，造成损坏。

During transportation, alloy aluminum plates may rub or squeeze against each other, causing damage.

解决铝板表面划伤的方法：

Method to solve surface scratches on aluminum plates:

1.合金铝板模具上的工作带需要打磨光滑，挤压模具的空刀是否足够，表面是否光滑。

1. The working strip on the alloy aluminum plate mold needs to be polished smooth, whether the empty blade of the extrusion mold is sufficient, and whether the surface is smooth.

2.生产合金铝板时，注意模具线条的产生。线条一旦产生，就要及时下模，停止生产。

When producing alloy aluminum plates, pay attention to the generation of mold lines. Once the lines are formed, they should be promptly removed from the mold and production should be stopped.

3.铝板锯切过程中:每次锯切都需要及时清理锯切锯末。防止二次划伤。

During the aluminum plate sawing process, it is necessary to clean the sawdust in a timely manner for each sawing. Prevent secondary scratches.

4.同样，在数控加工铝板的过程中，也需要防止夹具上残留的铝渣伤。

4. Similarly, in the process of CNC machining aluminum plates, it is also necessary to prevent residual aluminum slag damage on the fixture.

出料轨道或摆床上有裸露的工业铝型材或石墨条内有硬夹杂物，应避免硬夹杂物与铝板接触时划伤合金铝板表面；

If there are exposed industrial aluminum profiles or graphite strips on the discharge track or bed with hard inclusions inside, it is necessary to avoid scratching the surface of the alloy aluminum plate when the hard inclusions come into contact with the aluminum plate;

在生产和搬运过程中要轻拿轻放，尽量避免随意拖动或翻动合金铝板；

During production and transportation, handle with care and avoid dragging or flipping alloy aluminum plates randomly as much as possible;
