Perforated metal plates often exhibit varying degrees of deformation after production, and are not as flat as the original material. This phenomenon is closely related to the manufacturing process and the raw materials used. Here, Anping Senchi Perforated Plate Factory offers a detailed explanation of why perforated plates experience deformation.
1. Deformation Caused by the Manufacturing Process
Perforated plates are typically produced using CNC punching machines, where the raw plate is pressed according to a specific mold. The alloy punching pins on the mold press the raw plate into the punching area. At the moment of contact between the punching pin and the plate, a significant amount of heat is generated. As the rest of the plate remains cooler, this temperature difference causes the heated area to cool rapidly, akin to an annealing process. After annealing, the hardness of the perforated plate increases, and internal stresses are generated, leading to deformation.
2. Influence of Material
The degree of deformation of perforated plates is closely related to the material used. Different materials result in different deformation behaviors. Typically, stainless steel perforated plates deform more easily than steel plates, and steel plates deform more easily than aluminum plates.
3. Influence of Hole Diameter and Hole Spacing
The size of the hole diameter and the spacing between holes are also significant factors affecting deformation. In general, the smaller the hole diameter and the closer the hole spacing, the more severe the deformation of the perforated plate. Smaller holes and tighter spacing increase the localized stresses on the plate, making it more prone to deformation.
4. Influence of Edge Margin
The design of the edge margin of the perforated plate also affects its deformation. The larger the edge margin, the more concentrated the forces during the punching process, increasing the likelihood of deformation.
In conclusion, the deformation of perforated plates is the result of multiple factors, including the manufacturing process, material choice, hole design, and more. Understanding these factors helps to take effective measures during production to minimize deformation and improve product quality and stability.
