In the home decoration market, almost every household can see the doors and windows made of aluminum alloy. How should the aluminum alloy doors and windows be processed? How can the quality of aluminum alloy doors and windows be distinguished? Next, I'll talk to you about the production methods and steps of aluminum alloy doors and windows.

 How to distinguish the quality of aluminum alloy doors and windows

1、 How to distinguish between good and bad quality of aluminum alloy doors and windows

1. Look at the section structure

Good aluminum alloy material cutting surface geometry angle is accurate, the profile is not easy to twist, the cutting angle is also correct. Not only that, the thickness of the cutting surface of the profile should be sufficient; on the contrary, the thickness of the lower profile will be falsely propped up by threading.

2. Look at the surface quality

The surface of good aluminum alloy material is full of luster and texture, and the spray paint is round and smooth; while the surface of the secondary aluminum alloy material is dull and lack of luster, it seems to be in full violation of the sense of harmony. After using for a period of time, the phenomenon of discoloration and fading will appear.

2、 Aluminum alloy door and window manufacturing method, steps

1. Preparation of materials

Aluminum alloy, aluminum alloy, aluminum alloy and so on. And different materials have different properties, we can choose according to the demand.

2. Broken material

Cutting material, also known as "blanking", is the first and most critical step in the production method of aluminum alloy doors and windows. Cutting tools are needed for cutting materials, and the cutting size should be accurate according to the design drawing, so as to ensure the squareness of doors and windows, and the error of cutting size should be controlled within 2mm. For example, right angle cutting method is used for sliding door; 45 ° cutting method is used for sliding door.

3. Drilling

The frame and leaf connection of aluminum alloy doors and windows is fixed by screws, so no matter what kind of assembly method is used, accurate hole position is required. Aluminum drilling, with a small drill or pistol type electric brick can be used; when operating, the hand gesture should be stable to avoid drilling skew. In order to facilitate better operation, we can make snap line positioning on the aluminum material and determine the position by reference material.

4. Assembly

Aluminum alloy door and window manufacturing method, aluminum alloy door and window assembly depends on connectors and screws to complete. The assembly methods are divided into three types: 45 °, right angle and vertical. If the vertical bar is to be connected with the vertical bar, then it should be fixed with the cross bar.

The above is about the aluminum alloy door and window manufacture method, the step and the aluminum alloy door and window quality how to distinguish good from bad. If we choose aluminum alloy doors and windows carefully, we should not only choose aluminum alloy doors and windows in daily life, but also choose aluminum alloy doors and windows.
