Why is the surface of some stainless steel perforated sheets very uneven

Stainless steel perforated sheets are mesh products made by continuously punching high-quality stainless steel sheets using specific molds on precision CNC machines. They are widely used in various industries and come in a wide range of specifications. However, some stainless steel perforated sheets may not be as flat as the original material after production. The main reasons for this phenomenon are as follows:
Punch Wear: Over time, punches gradually wear down. If the wear is severe, not only will it cause the edges of the perforated sheet to become uneven, but it may also lead to sheet breakage during punching, making it more difficult to flatten the sheet afterward.
Excessive Mold Clearance: When producing stainless steel perforated sheets, the clearance in the mold needs to be precisely adjusted. If the mold clearance is too large, it directly leads to deformation of the sheet during punching, affecting the flatness. This is particularly evident when producing perforated sheets with larger hole diameters or special hole spacing.
Small Hole Spacing: The smaller the hole spacing, the greater the impact of uneven stretching and stress on the sheet. This causes the stainless steel perforated sheet to deform more easily. The punching process with small hole spacing accentuates this effect, leading to greater deformation of the material.
Poor Material Quality: Using low-quality stainless steel sheets increases the likelihood of uneven internal stresses in the material. This results in deformation during processing, which ultimately affects the flatness of the final product.
For some special specifications, such as perforated sheets with larger hole diameters, thicker plates, or smaller hole spacing, the sheet metal undergoes more stretching during production. This makes it much harder to flatten the sheet afterward, resulting in greater surface deformation.
