         The adhesive corner code for doors and windows is a whole, and the structure of the adhesive corner code is sturdy. Coupled with the coordination with the pin, it can solve the problem of loose movable corner codes, greatly improving the performance of the entire window. Therefore, high-performance system doors and windows are increasingly choosing adhesive corner codes for splicing.

          The strength and sealing of the processing corners of aluminum alloy doors and windows are very important, determining the splicing strength and waterproof degree of the doors and windows. The corner code is injected with glue. The traditional corner assembly process for ordinary doors and windows adopts a connection form of extruding aluminum corner codes and injecting glue into the corner codes, and then applying sealant to the extruded corner parts. However, for the aluminum profiles that truly need to be sealed, the interior of the joint cavity is injected with glue into the corner code sealant. Rainwater will enter the inside of the doors and windows through the fine seams of the joint, and this process is not easy to ensure the compactness of the corner assembly and the sealing of the joint.
