By comparing the angular strength tests of ordinary group angles and injection angle code group angles, it can be concluded that under the same deformation conditions, the angular strength of the injection angle group can be increased by about 5.7 times.

Colloids slightly foam and expand during the solidification process, forming elastic pads between metal to metal connections, effectively reducing the transmission of various forces, acting as shock absorbers and buffering pads, while improving the insulation, airtightness, water tightness, and sound insulation properties of doors and windows.

The use of perforated glue injection will increase the cost of glue, but it can greatly reduce its overall cost by being installed in one go.

With the improvement of people's living standards, there are higher requirements for the living environment. The requirements for doors and windows are no longer limited to the degree of use, but more about various performance indicators of doors and windows, as well as the length of their service life. In particular, the introduction and standardization of energy-saving indicators in various regions have become more stringent, and new requirements have been put forward for the sealing and insulation performance of doors and windows. Making better doors and windows has become a trend. The use of special corner adhesives for adhesive corner codes can improve the strength and sealing of aluminum alloy door and window corners, and create high-quality aluminum alloy door and window products.
