The final quality of doors and windows is closely related to the processing capacity of the factory, and one important indicator is the corner joint and aluminum corner code. The connection between two profiles at the corner of a good door and window is achieved by using aluminum corner codes. Then, a corner forming machine is used to squeeze the profiles and corner codes together, and two-component adhesive is injected into the holes to solidify the corner code frame material together. Common low-quality practices include splicing without corner codes, not applying curing glue when there are corner codes, or deceiving consumers with a little bit of glue on the mouth. In addition, the quality can also be judged by touching the seam of the corner assembly with your hand, and the smoother it is, the better the quality of the corner assembly processing.

Corner strength, corner code. It is one of the most important performance indicators for evaluating the quality of doors and windows! In the building environment, doors and windows are subjected to various forces, such as opening impact, wind pressure, temperature change stress, etc. The connection angle strength of the frame is insufficient, which can lead to corner opening and connection deformation, losing the basic frame retention ability of doors and windows, causing problems such as door and window leakage and inability to open normally, seriously affecting the sealing and safe use of doors and windows. Maintaining the basic frame stability of doors and windows is a prerequisite for all performance!

Glue injection is a specialized adhesive used to fill the gap between aluminum corner codes and profiles, known professionally as corner glue. It is similar to the traditional mortise and tenon connection structure of Chinese furniture. Before connecting, wood glue is often applied to the contact surface between the mortise and tenon joints. This not only makes the connection more secure and less likely to loosen even under impact, but also makes it more sealed through filling. The glue injection for doors and windows is functionally the same as the wood glue for traditional mortise and tenon connection structures in China, aiming to improve the stability and sealing of windows, except that the glue injection process for doors and windows is more stable.
