3. ​​Apply an appropriate amount of \”corner glue\” to the effective contact surface between the corner code and the profile and the connection section of the profile, and check whether the reinforcing sheet is installed.

4. Insert the corner code, align it along the corner seam, and use the \”corner assembly machine\” on this corner to complete the positioning and fixing process

5. . After the four corners of the door and window are positioned and fixed, the size and flatness should be confirmed and adjusted within 30 minutes.

6. After cornering the casement window frame, use corner glue to inject glue under pressure until the corner hole overflows with glue (see page 121).
