First of all, the material selection is crucial. The aluminum used in the connection parts must ensure that its strength matches the main materials of the window frame and sash to avoid uneven force due to material differences. At the same time, surface-treated aluminum materials, such as anodized or powder-coated, should be preferred, which can not only enhance corrosion resistance, but also ensure the lasting beauty of the appearance, providing a solid foundation for subsequent stable connections.
In terms of connection methods, hinge connection and corner code connection are common. Hinge connection is suitable for windows that need to be opened and closed frequently. When choosing hinges, pay attention to their load-bearing capacity, material quality and smoothness of opening and closing. High-quality stainless steel hinges can bear the weight of the window sash, and are not easy to rust or deform during long-term use, ensuring that the window sash opens and closes smoothly and silently. When installing the hinge, its position and angle should be adjusted accurately to ensure that the window sash and window frame fit closely and the gap is uniform. Generally, the gap should be controlled within 1-2 mm, which can ensure smooth opening and maintain good sealing.
Angle code connection is mostly used for large windows or curtain wall systems with high structural strength requirements. The material of the angle code is usually aluminum alloy, and its shape design should fit the splicing angle of the window frame and the window sash, which is generally 45 degrees or 90 degrees. When installing the angle code, high-strength special screws should be used for fastening. The length and diameter of the screws should be reasonably selected according to the thickness of the aluminum material to ensure that the angle code can firmly fix the window frame and the window sash together to form a stable frame structure and effectively resist wind pressure and external force impact.
Sealing treatment is a key link in the connection process. High-quality sealing strips should be embedded in the connection between the window frame and the window sash. The strips should have good elasticity, weather resistance and anti-aging ability, such as EPDM rubber strips. The installation of the rubber strips should be tight and continuous, without any breakpoints or gaps, to prevent rainwater and air leakage, and ensure the airtightness and watertightness of the window.
Processing accuracy should also not be ignored. The cutting and punching of window frames and window sashes must be strictly carried out in accordance with the design dimensions, and the error should be controlled within a very small range, usually not exceeding 0.5 mm. High-precision processing can ensure the tight fit of the connection parts and avoid problems such as loose connection and poor sealing due to dimensional deviation.
Quality inspection is also an important step. After the connection is completed, the window should be fully tested for performance, including airtightness, watertightness, and wind pressure resistance. By simulating different climate environments and external forces, check whether the connection between the window frame and the window sash is stable and whether the sealing is effective. If there are any problems, adjust and improve them in time to ensure that the aluminum alloy thermal insulation external casement window can play the best comprehensive performance of thermal insulation, sound insulation, and waterproofing after installation, providing comfort and safety for the home environment.
