How to distinguish the quality of perforated mesh
1. First, visually inspect the appearance of the perforated sheet material; a smooth surface with no defects and no dings around the edges is of premium quality. 2. Use the chemical experiment method to verify the purity of the sheet material; the higher the purity, the better the quality, especially at our scaffold perforated sheet factory. 3. Measure the length, width, and thickness of the sheet material to ensure they meet specifications. 4. Check the diagonal measurement of the sheet material against the required tolerance or drawing specifications. 5. Visually inspect the hole diameter for qualification and check for any overlapping or skipped needle issues. 6. Measure the hole diameter to ensure it meets the required standards. 7. Measure the hole spacing to ensure it meets the required standards. 8. Measure the edge allowance to ensure it meets the required quality.
Believe it or not, users familiar with steel plate perforated sheets are aware that various materials experience different degrees of deformation after processing. Some sheets become cylindrical even after they are finished. The exact cause of the unevenness is often a mystery to users. Here, we take this opportunity to explain why perforated plates may exhibit uneven stamping.
Reason one: Material-related. The degree of deformation after stamping varies among different materials. The deformation of stainless steel is particularly difficult to flatten, which is due to the stiffness of stainless steel. Jinan Punching Mesh Factory, it possesses certain elasticity, making it challenging to achieve the same level of flatness as before stamping after the flattening process.
Reason two: Related to the hole diameter and spacing. The smaller the hole, the denser the spacing, and the poorer the flatness. During the CNC stamping process, when the stamping needle and the stainless steel perforated sheet are subjected to force, the stamping process is akin to tempering the stainless steel plate. As a result, the plate becomes harder and is not easy to flatten.
Reason three: The edge of the board affects flatness. The larger the edge, the worse the flatness, especially for boards with a high rate of openings and larger hole sizes. Moreover, if the white space around the four edges is substantial, it is particularly difficult to flatten. However, rest assured, we have flattening equipment that will strive to flatten the boards as much as possible for the convenience of our customers.
In summary, after stainless steel perforated plates are processed, they all require flattening. The "flatting" process involves using flattening machines and other equipment to restore the perforated plates to their original flat condition. Moreover, it is common to clean the perforated plates after flattening, using lubricants for treatment, thereby making the CNC perforated plates cleaner. In the flatting process, to minimize errors during the manufacturing of the perforated plates, it is essential to determine the method of processing and the appropriate molds before production, as well as the best method of stamping for achieving better flatness in the final product, ensuring precision in CNC perforation.
