when doors and windows, we often pay more attention to the quality and price of large products such as door & window profile, hardware accessories, glass types, etc., but few people notice the splicing method of door and window corners, few people know the corner setting technology of doors and windows. Experienced people will not only pay attention to the quality of profiles and glass, but also understand the corner setting process of fan frames.
The function of set angle is to increase the angle strength of doors and windows, maintain the stability of the basic frame of doors and windows, and at the same time ensure that there will be no seepage in the corners of doors and windows.
Generally speaking, angle setting process can be roughly divided into pin glue injection process, movable angle code process and angle collision process. Each of these three corner sets has its own advantages and is suitable for different scenarios and environments.
Pin glue injection process"
the angle code used during pin glue injection is a combination of angle code film made of nail handle material and pure aluminum corner brace with a thickness of 4.0-5.0mm. Therefore, the angle code has stronger toughness and stability. When assembling doors and windows, we often use more weather-resistant corner glue for coating and sealing to enhance the overall sealing performance of doors and windows.
The angle code used in this process has pin pin position, and dowel hole and glue injection hole are processed at the corresponding position of the profile corner. The frame can be assembled without using a pin gun, after assembly, glue injection is carried out to ensure angular strength and waterproof.
Activity angle code process"
the movable angle code process is connected to aluminum through spring buckle, and the doors and windows are fixed by screw tightening. The left and right structures are detachable and installed, which is convenient to disassemble and assemble, and easy to group frames, however, it is not suitable for positions with high waterproof requirements, because the movable angle code process is difficult to realize glue injection, and water seepage hidden danger is easy to occur in the later stage; It is usually used in the case that the ore body with low waterproof requirements is too large to enter the elevator, the advantages of the movable angle code are reflected, which is convenient to disassemble and assemble.
Angle collision process"
the angle collision process is to apply section glue on the surface of aluminum alloy profile first, insert the angle code into the profile cut by 45 °, and carry out backlog link through angle collision machine, this process is usually used together with diversion injection glue. Angle strength and angle waterproof performance are very excellent.
Features of the three processes
among the three processes, the angle collision process is commonly used now. Years of process accumulation have made this process very perfect. In recent years, more and more pin glue injection processes have been adopted, because its assembly tools are simple and easy to operate, they are more and more popular; The movable angle code is relatively mainly used for door and window products under specific conditions.
