鋁板表面劃傷的原因：

Reasons for scratches on the surface of aluminum plates:

劃傷，擦傷，碰傷。

Scratches, abrasions, bumps.

合金鋁板

Alloy aluminum plate

1.合金鋁板在生產過程中鋁流經工作帶時，這些偏析浮出物或堅硬的工業鋁型材顆粒附著在工作帶表面或損壞工作帶，最終劃傷型材表面。

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.合金鋁板模具或工作帶上有雜物，模具工作帶硬度低，擠壓工作帶表面時會劃傷鋁板。

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.出料軌道或擺床上有裸露的鋁或石墨條內有硬夾雜物，當與鋁接觸時，會劃傷合金鋁板表面。

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.在擺床上人工拖動合金鋁板造成擦傷。

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

5.合金鋁板在運輸過程中相互摩擦或擠壓，造成損壞。

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

解決鋁板表面劃傷的方法：

Method to solve surface scratches on aluminum plates:

1.合金鋁板模具上的工作帶需要打磨光滑，擠壓模具的空刀是否足夠，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.生產合金鋁板時，注意模具線條的產生。線條一旦產生，就要及時下模，停止生產。

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.鋁板鋸切過程中:每次鋸切都需要及時清理鋸切鋸末。防止二次劃傷。

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

4.同樣，在數控加工鋁板的過程中，也需要防止夾具上殘留的鋁渣傷。

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

出料軌道或擺床上有裸露的工業鋁型材或石墨條內有硬夾雜物，應避免硬夾雜物與鋁板接觸時劃傷合金鋁板表面；

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;

在生產和搬運過程中要輕拿輕放，盡量避免隨意拖動或翻動合金鋁板；

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