Perforated aluminum panels are a type of aluminum panel product, primarily completed during the sheet metal processing stage. After marking the angles with punches, the perforation can be carried out using a CNC punch press. The perforation rate is one of the three key factors for perforated aluminum panels. When customers usually want to customize perforated aluminum panels, they need to know the perforation rate. How do you understand the perforation rate of perforated aluminum panels? Before performing the aluminum panel perforation operation, it is essential to comprehend the meaning of the perforation rate, as it greatly affects the quality of the perforation. Generally, the perforation rate can be calculated based on the size of the holes specified by the customer. Perforation Rate = Area of Perforations / Total Surface Area of the Finished Aluminum Panel. In a general sense, this refers to the spacing between each hole, indicating the density of the holes on the panel. A high-precision perforation rate can make the aluminum panel look more aesthetically pleasing and more attractive.
