[China Aluminum Industry Network] With the implementation of the national building energy conservation policy, the application of cold-aluminum alloy doors and windows with heat insulation is becoming more and more widespread. Currently, there are two kinds of insulation aluminum profile production technologies on the market of insulation aluminum profiles: It is a strip-type heat insulation technology originated in Europe, and the other one is a rubber-injection heat insulation technology from North America. European wear strip type and North American cast-in-place heat insulation aluminum profiles all have better thermal insulation properties. Compared with them, wear-in-strip heat insulation aluminum profiles can easily realize the inside and outside two-color door and window systems to meet the high aesthetic requirements of customers. However, due to equipment limitations, the product has a larger cross-section and the cost of doors and windows is higher. The plastic injection-type heat insulation aluminum profile has a compact structure, a small and beautiful appearance, and a relatively small cross section, which can save the amount of aluminum used, but the profile of the cut metal bridge deforms greatly, and the bridge is cut. When the noise is large, the environmental performance of the process is poor and the aluminum loss is large. The large-section profiles and the double-color door and window systems inside and outside are difficult to achieve. At present, some of the larger aluminum plants in China have introduced and produced these two technologies and equipment, which has played a major role in promoting the development and progress of China's thermal insulation and energy saving aluminum materials. After years of practice, we have found them. All of them have their own defects and limitations. Therefore, it is urgent to develop a new type of heat insulation aluminum profile and its door and window system with both advantages. In order to overcome the limitations of the technology and equipment of existing energy saving aluminum production technology for broken bridges, a single insulated heat insulation strip is used instead of two solid heat insulation strips, and a single heat insulation strip aluminum profile technology capable of ensuring the mechanical properties of the composite profiled section is adopted. It has become an urgent demand and technical bottleneck for the research and development of energy-saving door and window systems for economic buildings. It has also become a difficult problem and a hot spot for research and development in the aluminum profile processing industry. With no increase or increase in costs, the requirements for energy saving in buildings have been achieved. Bridge energy-saving aluminum profile promotion. After the successful development of a new energy-saving aluminum alloy profile technology with a single hollow thermal insulation strip, in principle, it can provide a platform for upgrading all existing product structure series, and solve the defects and limitations of the existing thermal insulation and energy-saving aluminum material technology. Many of the design and product structure bottlenecks caused by it have greatly promoted the upgrading of industry products and technologies.
