System doors and windows are mainly divided into window frames, sash frames, hardware, glass, adhesive strips and other accessories. During the production process, each module component needs to be processed separately according to the order, and then directly stored in the warehouse as needed and shipped to the construction site for final assembly.

There are 4 general processes for the processing of doors and windows in the system

1. Frame material processing

(1) Frame cutting. According to the parameters of the production order, the frame material after the strip is cut. Usually, the blanking scheme can be optimized according to the order situation, increase the full use of the frame material, and save costs.

(2) Hole and groove processing of frame material process. According to the window design and the requirements of the production order, the frame material is processed with specific holes and grooves.

(3) Cutting of the middle mullion material. Combined with the window design and the requirements of the order parameters, the cutting and processing of the middle mullion material can optimize the blanking scheme according to the order situation.

(4) Mignon end face milling. The mullion material is further processed to make its end face shape meet the installation requirements.

(5) Corner code cutting of frame material. Depending on the window series, select the corner code of the corresponding model for cutting processing of a specific size.

(6) Frame material group angle. According to the process flow of different angles, the frame material is connected with the corners. The process accuracy of this step determines whether the finished product is flat. The high-precision process can improve the accuracy of the assembly angle, thereby improving the aesthetics and waterproofness of the window type.

(7) Mullion joint. After the window frame group angle is completed, the frame mullion connection can be carried out, and the processed mullion material can be assembled to the window frame, and the appropriate assembly process can be selected according to the requirements.

(8) Frame hardware assembly. According to the processing process, the corresponding frame hardware is assembled perfectly.

2. Fan material processing

(1) Fan cutting. The basic processing process of fan material is similar to that of frame material, and it is also necessary to pay attention to the problem of machining accuracy.

(2) Fan material process hole and groove processing. Specific holes and grooves are machined for hardware installation to facilitate subsequent installation.

(3) Fan corner code cutting. Select the corner code that meets the requirements for cutting and processing, and prepare for the assembly of the corners.

(4) Fan group angle. According to the process requirements in the order, the fan material is processed reasonably.

(5) Fan hardware assembly. Usually in this process, the assembly of door and window handles is carried out. Precision machining and installation can give full play to the performance of the handle, which can not only improve the operating feel, but also optimize the use effect and service life of the handle.

3. Accessories processing

(1) Crimping cutting. The crimping line, also known as the bead, is usually applied to the window frame or sash frame and plays a fixed role in the installation of glass.

4. Final assembly

In order to facilitate transportation and installation, system windows and doors are usually shipped as semi-finished products for installation and final assembly at the construction site.

(1) (fix the window frame to the window hole) frame sash assembly, assemble the frame and sash with good angles, assemble the hardware and glass installation.

(2) Window inspection, full-time inspectors inspect relevant items according to door and window standards, and confirm acceptance with customers.
