Manufacturing Process of Aluminum Alloy Doors and Windows: The manufacturing process of aluminum alloy doors and Windows is divided into four steps: 1. Cutting materials →2. Drilling →3. Assembly →4. Protection or packaging. 1. Cutting materials Cutting materials, also known as "blanking", is the first and crucial process in the production of aluminum alloy doors and Windows. Material cutting mainly uses cutting equipment. The length of the material should be determined according to the design requirements and by referring to the detailed construction drawings of doors and Windows, and the cutting should be accurate. Otherwise, the squareness of the doors and Windows cannot be guaranteed, and the error value of the broken material size should be controlled within 2mm. Generally speaking, when cutting materials for sliding doors and Windows, it is advisable to use right-angle cutting. When cutting materials for casement doors and Windows, it is advisable to use 45° Angle cutting. For other types, the cutting method should be selected based on the assembly method.
