By comparing the angular strength tests of ordinary group angles and injection angle code group angles, it can be seen that under the same deformation conditions, the angular strength of the injection angle group can be increased by about 5.7 times. Colloids foam and slightly expand during the curing process, forming elastic pads at the metal to metal connections, effectively reducing the transmission of various forces, playing a role in shock absorption and buffering, and improving the insulation, thermal insulation, airtightness, water tightness, and sound insulation performance of doors. The use of perforated adhesive will increase the cost of the adhesive, but once in place during installation, it can greatly reduce its overall cost.
