There are two kinds of effects, static and dynamic, which must be satisfied at the same time. This determines the delicate degree of aluminum alloy door and window hardware technology from the essence. We are not difficult to find in many exhibitions, many aluminum alloy doors and windows enterprises, aluminum alloy doors and windows appearance is quite good. Electrophoretic aluminum, even fluorocarbon sprayed aluminum, with insulating glass, has bright colors and various styles, but its operability is not satisfactory when it is opened and closed. Inflexibility, shaking and other problems occur frequently, which is the result of not paying attention to the hardware accessories of doors and windows.
The real qualified and excellent quality aluminum alloy door and window system is the perfect combination of aluminum alloy door and window hardware and profiles. Besides appearance, systematization of hardware is more important. As the core components of aluminum alloy doors and windows, hardware not only meets the physical and mechanical properties of aluminum alloy doors and windows, but also is responsible for the operability, adjustability, safety, applicability, standardization and serialization of aluminum alloy doors and windows.
The production of high-grade aluminum alloy door and window hardware is extremely strict, using precision mold and high automation production to ensure that each product is highly accurate. Product design, plot, stress and material strength are all calculated strictly. Most of the materials used are stainless steel, aluminum alloy, zinc alloy and high-quality engineering plastics. There are some factories in order to greedy cheap, using ordinary carbon steel to make, the result is not a few months, began to rust. The aluminum alloy door and window material is very dangerous, and only the safety diagram is changed once.
Some people will ask, so high-precision high-quality hardware and high-quality profiles can not make a qualified good aluminum alloy doors and windows? The answer is no, because from accessories, profiles to a complete aluminum alloy doors and windows, it is not a simple mechanical assembly and splicing. A large amount of professional knowledge of aluminum alloy door and window system is used. Every aluminum alloy door and window company should make great efforts to design and manufacture the system engineering, and coordinate with all aspects, especially hardware accessories.
Many times, we often hear people complain that the aluminum alloy doors and windows are so inflexible, just blame the hardware accessories, but ignore other problems, such as the quality of adhesive strips and profiles, the accuracy of the notch (such as the size of the notch should be the size after surface treatment), the processing precision of the angle group, etc.
The quality of aluminum alloy doors and windows is determined by a series of complete quality assurance system. Therefore, the production of aluminum alloy doors and windows must pay attention to the system engineering of every production link, especially the role of removing the hardware of aluminum alloy doors and windows fundamentally. At the same time, scientific and systematic solutions of aluminum alloy doors and windows will also be the magic weapon for aluminum alloy doors and windows enterprises to win.
In fact, the production of single aluminum alloy door and window hardware is no worse than that of European countries in terms of technology and production technology, but there is still a big gap with them in the overall system of aluminum alloy doors and windows, which is also the direction of our country's aluminum alloy door and window industry in the future.
