Limitations in the Manufacturing Process of Perforated Sheets

Although perforated sheets can be manufactured in various hole shapes and specifications, such as round, oval, diamond, fish scale, and more, with hole diameters ranging from 0.5mm to 200mm, thicknesses from 0.3mm to 20mm, and materials like steel, aluminum, stainless steel, copper, and nickel, there are still certain technical limitations in their production. These limitations are primarily as follows:
Perforated Sheet
Relationship Between Hole Diameter and Sheet Thickness
The production of perforated sheets must adhere to the "minimum hole principle," which states that the hole diameter should be greater than or equal to the sheet thickness. For instance, it is not possible to punch a 4mm hole in an 8mm thick sheet. This is because when the hole diameter is smaller than the sheet thickness, the punching tools and dies cannot withstand the excessive pressure, making production unfeasible.
Smaller hole diameters and thicker sheets significantly increase production difficulty.
Material hardness also impacts processing difficulty. For example, manufacturing perforated stainless steel sheets is more challenging than steel sheets due to the higher hardness of stainless
steel, which causes greater wear on dies and punches.
Limitations on Hole Spacing
The distance between holes must meet a minimum requirement. Typically, the distance from one hole edge to another should be no less than 1.5 times the sheet thickness. If the spacing is too small, it not only increases production difficulty but also causes more severe deformation of the sheet, affecting the quality of the final product.
Production Challenges and Material Characteristics
The hardness and ductility of different materials directly affect the ease of manufacturing perforated sheets. Harder materials, such as stainless steel or nickel, are more challenging to process compared to softer materials like aluminum or mild steel.
Higher material hardness demands better tooling and results in faster wear and tear on the dies and punches.
Conclusion
While perforated sheets can be customized in various shapes and sizes, strict adherence to technical limitations is essential. Hole diameters must be compatible with sheet thickness, and minimum hole spacing requirements must be met to ensure manufacturability and product quality. Selecting appropriate materials and design parameters helps reduce manufacturing challenges and improve efficiency and tool longevity.
