如今，無論是商用還是家庭車庫電動卷簾門，總能避免一些劃痕或裂縫。 正是因為這些缺陷的范圍太小，不值得找廠家維修，導致卷簾門上的“傷疤”越來越嚴重 ，失去了原有的光澤。 人士介紹的一個簡單的方法，由于模具表面擠壓粗糙，有很深的冷切刀痕、磨痕和凹凸痕，電動卷簾門被劃傷。

Nowadays, whether commercial or family garage electric roller shutter doors can always avoid some scratches or cracks. It is precisely because the scope of these defects is too small to be repaired by the manufacturer, resulting in more and more serious "scars" on the roller shutter door, losing its original luster. A simple solution introduced by professionals. Due to the rough extrusion of the die surface, there are deep cold cutting knife marks, grinding marks and concave convex marks, and the electric roller shutter door is scratched.

1、擠壓模經過強韌改性處理，使其具有良好的紅硬性能、耐磨、耐劃傷性能。

1. The extrusion die has good red hardness, wear resistance and scratch resistance after strong and tough modification.

2、電動卷簾門用于維護硬質合金模具。 通過鐓粗和復合強硬熱處理，模具工作表面具有高硬度、紅硬性、耐磨性、抗疲勞性、抗咬合性、抗粘著性、耐腐蝕性和抗劃傷性。

2. The electric roller shutter door is used to maintain the cemented carbide mold. Through upsetting and composite hard heat treatment, the working surface of the die has high hardness, red hardness, wear resistance, fatigue resistance, anti seizing, anti adhesion, corrosion resistance and scratch resistance.

3、使用精制型電動卷簾門維修產品，具有純度高、雜質少、晶粒細、碳化物小、各向同性性能優良、化學成分和組織均勻等特點。

3. The refined electric roller shutter door maintenance product has the characteristics of high purity, less impurities, fine grains, small carbides, excellent isotropic performance, uniform chemical composition and structure, etc.

4、選擇工作帶的寬度，生產一定數量的電動卷簾門維修件后，對模具表面和工作帶進行拋光，以保證工裝模具和擠壓設備的裝配精度。

4. Select the width of the working belt, and polish the die surface and the working belt after producing a certain number of maintenance parts of the electric roller shutter door, so as to ensure the assembly accuracy of the tooling die and extrusion equipment.

此外，檢查工作也要做好。 濟南電動卷簾門安裝維修廠家建議您可以做到以下幾點：

In addition, the inspection work should also be done well. Jinan electric roller shutter door installation and maintenance manufacturer suggests that you can do the following:

人工檢查卷簾門區域：

Manual inspection of Jinan roller shutter door area:

1、檢查卷簾門滑軌、門扇是否變形卡死，手動按鈕盒是否完好。

1. Check whether the sliding rail and door leaf of the rolling shutter door are deformed and stuck, and whether the manual button box is intact.

2、指示卷簾門標志的電器箱是否正常，箱體是否完好。

2. Whether the electrical box indicating the sign of roller shutter door is normal and whether the box is intact.

3、打開按鈕盒門，檢查按鈕是否可以正常使用。

3. Open the button box door and check whether the button can be used normally.

卷簾門自控檢測方面：

Jinan roller shutter door automatic control detection:

1、用點燃的香煙或其他煙源測試系統中的任一煙感，如發現無法開啟，請及時檢查維修。

1. Test any smoke in the system with a lighted cigarette or other smoke source. If it is found that it cannot be opened, please check and repair it in time.

2、清潔卷簾并灰塵。 若油漆局部變形，應進行修補，以保證卷簾門外觀整潔美觀。

2. Clean the roller shutter and remove dust. If the paint is partially deformed, it shall be repaired to ensure that the rolling shutter door is clean and beautiful.
