Many people find that after purchasing Stainless steel Perforated sheets, the backside of the mesh plates often have some burrs, which makes them think that this is a sign of a defective product. So, is it normal for Stainless steel Perforated sheets to have burrs on the backside? Let’s address this question based on our factory’s experience.
Stainless Steel Perforated Sheet
Stainless steel Perforated sheets are made by punching stainless steel plates. During the punching process, the punch tool applies strong pressure to the stainless steel sheet, creating holes that can resemble a tearing effect. This is an unavoidable part of the punching process. Since stainless steel has certain adhesiveness, burrs inevitably appear on the backside of the Stainless steel Perforated sheet to some extent. However, due to differences in production techniques across manufacturers, burrs can vary in severity—from mild to significant.
We typically use the method of touch to assess the size of the burrs. If you lightly run your finger over the backside of the Stainless steel Perforated sheet and feel a slight protrusion, with the height ranging between 0.1mm to 0.2mm, this is considered a mild burr and is normal.
However, if the burrs are large enough to cut your finger, this is no longer considered normal. This situation is usually caused by issues in the punching process, such as severe wear of the punching die or improper die grinding techniques. In such cases, burrs not only affect the appearance of the Stainless steel Perforated sheet, but they could also compromise its safety and overall quality.
To avoid excessive burrs on Stainless steel Perforated sheets, manufacturers should regularly check their punching equipment, especially the wear condition of the punch dies. After a certain period of use, excessive wear of the punch die can cause burrs to grow larger, so regular maintenance or replacement of worn punch dies is an important measure to prevent burr issues. Additionally, adjusting the punching pressure and speed can also help reduce burr formation.
In summary, mild burrs on the backside of Stainless steel Perforated sheets are a normal phenomenon and a common occurrence in the punching process.
