Problems in the production process of aluminum alloy doors and windows profile
Thermal break aluminum doors and windows are a highly valuable type of aluminum profile that significantly improves energy efficiency compared to traditional aluminum alloys. These profiles are designed with a thermal break bridge, which effectively insulates against heat transfer, making them ideal for modern construction and home decoration projects. Their key features include high strength, excellent insulation performance, multi-chamber structures, and good durability, all contributing to their widespread use in the building industry.
The thermal break aluminum alloy profiles are made by inserting non-metallic materials with low thermal conductivity between two aluminum sections, creating a composite structure that offers both insulation and structural integrity. This technology not only enhances energy efficiency but also provides superior fire resistance, corrosion resistance, and sound insulation. These characteristics make them an essential choice for architects and builders aiming to meet modern environmental and energy-saving standards.
One of the most advanced methods in this field is the "piled broken bridge" technique, which involves injecting a thermally insulating material into the profile’s cavity and then cutting the temporary metal bridge to isolate the two parts. Another method uses high-density polyamide (PA66) or PVC strips combined with aluminum through a rolling process, resulting in a strong, durable, and thermally efficient product.
During the casting process, it's crucial to maintain proper temperature and humidity levels. The ambient temperature should be between 18°C and 30°C, with humidity below 50%. Any deviation can lead to cracking or poor adhesion. Additionally, the surface of the heat-insulating tank must be clean and free from dust or grease, as any contamination can weaken the bond.
Bubbles in the mixture may indicate moisture exposure, so the casting area must be checked regularly. When stacking the poured profiles, they should be placed flat on hard surfaces with appropriate supports to prevent deformation. The blade used for breaking the bridge should be set to 75-100% of the required width, ensuring a complete cut without damaging the insulation material.
In the wear strip process, attention must be paid to tooth depth during the cutting stage. If the teeth are too deep, they need to be carefully removed; if too shallow, the entire batch may require rework. Mistakes in this stage can lead to production halts or defective products, emphasizing the importance of precision and quality checks.
Another common issue is the misuse of tapes or strips due to human error. To avoid such problems, clear labeling and detailed instructions on the scheduling board are essential to ensure that employees follow the correct specifications.
Overall, thermal break aluminum profiles represent a significant advancement in sustainable building materials. By strictly following the production guidelines, manufacturers can ensure that their products meet both customer expectations and market demands, offering a reliable, energy-efficient solution for modern architecture.
