Aluminum alloy door and window refers to the frame, wooden stick, fan of doors and windows which are made of aluminum alloy, and it is called aluminum door and window for short.

 

Window materials and accessories should be consistent with the existing national standards, industry standards or local standards. That is to say we should strictly control the deviation of material thickness so as to ensure the wall thickness is conformed to the design size and mandatory provisions of national standard.
 

In addition to the stainless steel, the material and accessories that we need to choose should be dealt with the anti-corrosion treatment so as to avoid the corrosion with aluminum material. The project of aluminum alloy doors and windows should be done in the workshop from beginning to the end and the specific process is as follows:

 

Profile blanking - punching milling - profile assembling - assembly layering - assembly casement – semi-finished product protection - storage.

Manufacturing department will send the profile banking sheet and working diagram provided by design department to the relevant operators.
 

Blanking process requirements and key points for operation:
 

Check the profile whether the surface is bright and clean with no obvious scratches, bruises or deformation. Also check the profile whether the color is uniform with integrated protective film and whether there is no foreign body in profile lumen.

Please go on the blanking according to the processing figure in same size and quantity. Profile cutting length tolerance is + / - 0.5 mm, angle tolerance is + / - 0.5 °and verticality deviation is ≯ 0.5 °. Please pay attention to that there is no obvious burr. Avoid the profile cutting in the process of cutting, handling and storage. The first article must be inspected and quarantined carefully and the manufacturing can be made only after making sure that the size is correct.

 

Assembly process and key points for operation:

Before assembling, inspection should be made on profile surface and size. Check whether the surface is clean and smooth without scratches. For the assembly surface, it should be no pollution, no oil contamination and the assembly should be done within two days after blanking in a timely manner. Check the quantity and size of the material according to the assembly drawing. If something wrong, please report it in time. It is strictly prohibited to blanking wrong components. After the assembling, profile surface should be smooth and unified and the height difference of the adjacent components should be less than 0.5mm.

Assembly dimension deviation is + / - 2.0 mm, and diagonal dimension deviation is + / - 3.0 mm.
 

Storage:

Products should be placed in a clean and smooth place. Product storage temperature should be less than 50 degrees Celsius and the length away from heat source is one meter more. Doors and windows at the scene of installation place should not exceed two months. When the temperature is 0 degree Celsius, doors and windows should be set aside in a greenhouse for 24 hours before installation. 

 

Products shall not directly contact with the ground, and padding should be 50 mm or more. Finished products should be put uprightly and the angle should be higer than or equal with 70 °, but there must have anti dumping measures. For the semi-finished product, it can be put flat. Make sure there is no pothole at the bottom, otherwise it may out of shape.
