The adhesive corner code compares the compressive strength of two products by placing the seamless welding corner assembly and the pin injection process corner assembly on a press machine and applying pressure.

After testing, seamless welding joints will deform and crack when subjected to an external force of 682 Newtons; The window angle of the pin injection process requires a pressure of over 1749 Newtons to deform and crack!

Why do we emphasize so much on the adhesive corner code assembly process? Because angular strength is one of the 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!
