Now most families like to choose aluminum alloy doors and windows to decorate their homes, but many people don't know how to make aluminum alloy doors and windows. Today, Jiangxi Aluminum Co., Ltd. explains several process steps for making aluminum alloy doors and windows.

Cutting: it is the first and key process of aluminum alloy doors and windows manufacturing. The cutting equipment is mainly used for cutting. According to the design scheme of each measuring size and the design requirements, the corresponding size is accurately cut. The error value of cutting size shall be controlled within 2mm.

Punching: generally, the frame and sash of aluminum alloy doors and windows are connected by screws. Therefore, punching is required at corresponding positions for both the assembly of horizontal and vertical bars and the fixation of accessories. Profile punching requires accurate position. It is not allowed to change the punching repeatedly on the profile surface, because once the hole is formed, it is difficult to repair.

Assembly: the aluminum profile is connected and assembled with screws through connectors according to the requirements. There are three assembly methods of aluminum alloy doors and windows: 45 ° angle butt joint, right angle butt joint and vertical butt joint. For the connection of horizontal and vertical bars, special connectors or aluminum angles are generally used, and then screws, bolts or aluminum rivets are used for fixation.
