As a modern building exterior wall decoration material, perforated curtain wall is widely used in commercial buildings, public facilities and high-end residential areas due to its unique visual effects, good ventilation performance and high structural strength. From material selection to process, the manufacturing process of perforated curtain wall covers multiple key links, each of which has a crucial impact on its final performance and quality. .

1. Material selection
The main materials of perforated curtain wall include panel materials, supporting structures and connectors. The choice of panel materials is directly related to the appearance, durability and functionality of the curtain wall.

Panel materials: Commonly used panel materials include aluminum plates, stainless steel plates, copper plates and galvanized steel plates. Aluminum plates are the most commonly used materials because of their light weight, corrosion resistance, easy processing and good ductility. Stainless steel plates are often used in places that require higher durability due to their high strength and excellent corrosion resistance. Copper plates are often used in buildings that pursue special aesthetic effects due to their unique oxidation discoloration effect. Galvanized steel plates are often used in projects with limited budgets due to their economy.
Support structure: The support structure is usually made of steel or aluminum alloy profiles to fix and support the panels. These profiles must have sufficient strength and rigidity to ensure the overall stability and safety of the curtain wall.
Connectors: Connectors are used to connect the panels to the supporting structure and are usually made of stainless steel or aluminum alloy to ensure long-term reliability.
2. Manufacturing process
The manufacturing process of the perforated curtain wall mainly includes design, punching, bending, surface treatment, assembly and installation.

Design: The hole type, hole diameter, hole spacing and overall layout of the panel need to be determined according to the building appearance requirements, functional requirements and environmental conditions during the design stage. After the design is completed, CAD software is used for precise drawing to provide accurate drawings for subsequent processing.
Punching: According to the design drawings, a CNC punching machine is used to punch the stamped sheet. The punching process requires strict control of the pressure and speed of the punching machine to ensure the uniformity and accuracy of the holes.
Bending: After punching, the sheet is bent according to the design requirements to form the required three-dimensional shape. This step is usually performed using a CNC bending machine to ensure the accuracy of the bending angle and size.
Surface treatment: In order to improve the corrosion resistance and aesthetics of the curtain wall, the panels usually need to be surface treated, such as fluorocarbon spraying, anodizing or powder spraying. These treatment processes not only enhance the durability of the panels, but also give them rich colors and textures.
Assembly: The panels, supporting structures and connectors are pre-assembled in the factory to ensure the accuracy and coordination of each component. The size and installation position of each component must be strictly checked during the assembly process to ensure the quality and performance of the final product.
Installation: After assembly, the curtain wall components are transported to the construction site for installation. The installation process must follow strict construction specifications and standards to ensure the stability and safety of the curtain wall. At the same time, attention should also be paid to the protection of the finished products during the construction process to avoid scratching or damaging the panels.
3. Quality control
The quality control of the perforated curtain wall runs through the entire manufacturing and installation process. From the inspection of raw materials to the monitoring of the processing process, to the inspection and acceptance of the final product, each link must strictly follow the relevant standards and specifications. In addition, the production equipment must be regularly maintained and calibrated to ensure processing accuracy and product quality.
