When we choose doors and windows, we always subconsciously pay 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. In fact, the strength (such as wind pressure resistance) and stability of doors and windows are not only related to door & window profile, but also closely related to the corner setting process of doors and windows. Delanshini doors and windows introduce the corner technology and classification of doors and windows.

what is the corner technology of doors and windows?
The corner assembly process of doors and windows is also called corner connection process. A complete door and window needs to be spliced by frame fan structural profiles, the key to the connection between the profile and the profile lies in the splicing of its corners (that is, the two profiles are riveted together at an angle of 90 ° or 45 ° with angle codes). 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 enable doors and windows to cope with various impacts such as man-made, windy, temperature changes, etc. Generally speaking, angle setting process can be roughly divided into: movable angle code process, angle collision process and pin glue injection process.

1 activity angle code process

the movable angle code process is connected to aluminum through spring buckle, and then the doors and windows are fixed by screw tightening. The advantage of movable angle code technology lies in its detachable installation, which is convenient, simple and easy to frame. The disadvantage of this process is that its connection is not tight enough, and the sealing is general; The water inlet is easy to make the spring rust lose elasticity or fracture.
2 movable angle code process
angle collision process: apply angle glue on the surface of aluminum alloy profile splicing, then insert the angle code into the 45 ° profile, and finally integrate the connection through precision machine Impact extrusion. The advantage of this splicing process is that it is seamlessly connected and is not easy to crack in water; However, the assembly of collision angle needs to be carried out during production, so the field Group frame is not supported.

3 pin glue injection process
the angle code used in pin glue injection process 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, so this angle code has stronger toughness and stability. When assembling doors and windows, we often use more weather-resistant corner glue to apply and seal to increase the overall strength of doors and windows.

after the science popularization is completed, let's talk about the differences. If a simpler and more direct metaphor is used to describe the movable angle code process, angle collision process and pin glue injection process, it is very suitable to use the traditional technique left by the ancestors-tenon joint.

the so-called tenon joint means that two pieces of material are made of Tenon, one is made of Tenon, and the two are worn together, and the two pieces of material are fixed together by the friction of the material.

the movable angle code process only inserts the tenon into the mortise (not necessarily box-lock tight). Such a set angle leads to insufficient firmness and easy shaking of doors and windows, and the flatness is not good and the gap may be obvious.
The angle collision process is like inserting a tenon into a mortise and tenon. In the gap between tenon and Tenon, a special glue is used to make a circle. Finally, a hammer is used to knock it tightly, in this way, the overall firmness of doors and windows is greatly improved (which can meet the needs of most home decoration doors and windows).

delanshini strives for perfection. New 115 series casement window adopts glue injection technology to block the corner gap, and firmly bond the corner to prevent loosening and cracking, which is conducive to safety.
