Step 1: Assemble the insulation strip with the aluminum profile
The aluminum profile and the insulating strip are pressed together through
a specific slot using a machine, resulting in a very stable combination. Through this
step, the window frame becomes a bridge-cutoff aluminum window frame. Coupled with the
cavity inherent to the aluminum material, the aluminum frame also possesses insulation
capabilities, effectively preventing the occurrence of cold bridges.
Step 2: Profile processing
According to the requirements of different window sizes, the frames are
cut to suitable lengths. At the same time, to meet the needs of splicing and hardware
installation, processes such as 45-degree angle cutting, drilling, and chipping are
further carried out on the window frames. We have different automated equipment to meet
the relevant processing requirements.
Step 3: Assembling the frame and sash
Assemble the cut frame components into a single unit, using corner
connectors at the joints and injecting two-component sealant to ensure the overall
strength of the frame and sash.
Step 4: Press the weatherstrip and install the glazing bead
Press a suitable sealing strip onto the frame sash, ensuring that the
appearance is straight and level after pressing, without any twisting or deformation.
The surface should be free of cracks, curling, or shortages, and the sealing should be
ensured. The model and color of the pressing line should correspond to the drawing, with
no obvious gaps or height differences.
Step 5: Hardware assembly and debugging
On the operation platform, the worker skillfully installed the hardware
that matched the windows. The hardware model and color were correct, the screws were not
loose, there were no omissions, and the opening was flexible without any noise.
