Aluminum-clad wood doors and windows are a new type of doors and windows as well as high-end doors and windows. Among several popular categories of doors and windows currently on the market, aluminum-clad wood doors and windows are sought after by many high-end door and window users for their excellent quality and beautiful appearance. It accounts for more than 70% of the entire high-end door and window market. The processing technology of aluminum-clad wood doors and windows is relatively complex, which is related to the structure of aluminum-clad wood doors and windows. As the name suggests, aluminum-clad wood doors and windows are composed of aluminum and wood profiles that can be connected through connectors. Because the wood part is painted four times, the entire production cycle of aluminum-clad wood doors and windows is longer than that of broken-bridge aluminum doors and windows.
Seamless welding process and angle connection process used in aluminum-clad wood doors and windows
1. Seamless welding
Advantages: The corner connection is beautiful and integrated, there are no splicing gaps, the corner watertight performance is good, and the corner strength is greatly affected by the welding quality.
Disadvantages: The process is complex, welding first and then painting, the processing efficiency is low; after painting, the paint film is uneven and has poor adhesion, easy to fall off, and high cost. The picture above shows the seamless welding of the middle mullion connection (welding can be It is divided into corner welding and mid-frame welding). If the welding is not strong, there is a risk of cracking and it is difficult to repair.
2. Group corner connection
Advantages: simple processing, low cost, and high processing efficiency.
Disadvantages: poor integrity and poor watertight performance at the corners, but this defect can be made up for by using glue-injected corner codes and glue-injected angle steel sheets.
How are the aluminum and wood in aluminum-clad wood doors and windows connected?
Aluminum and wood are mainly connected with buckles.
Reason: Under the same temperature and humidity, the expansion coefficients of aluminum and wood are different, so the deformation is also different. When snap connections are used, the expansion (shrinkage) of aluminum and wood does not affect each other, which can extend the service life of doors and windows.
Advantages of aluminum-clad wood doors and windows:
(1) It has the characteristics of pure wooden windows;
(2) The appearance is more beautiful and luxurious;
(3) Superior performance, energy saving, environmental protection, sound insulation, heat insulation, heat preservation, air tightness, and wind pressure resistance;
(4) The exterior aluminum has various colors and can be integrated with the building;
(5) Aluminum has excellent corrosion resistance and can extend product life;
(6) High market recognition;
(7) Easy to clean and maintain.
Disadvantages of aluminum-clad wood doors and windows:
(1) The overall cost is high. Raw solid wood is relatively scarce and the overall cost is high;
(2) There are many processes and high costs.
(3) The process requirements are high and the yield is low.
