Perforated metal sheets are produced by continuous punching on a CNC machine using stainless steel sheet material. There are several types of punching methods:
1. Continuous punching in the same direction: This method uses a long rectangular punching net mold to overlap the processing of long-shaped holes and edge cutting.
2. Continuous forming: This method of forming a larger shape than the punching net mold, such as large-sized louvers, rolling ribs, and rolling steps.
3. Gnawing: This method uses a small round mold to continuously punch arc-shaped holes with a small step distance.
4. Multi-directional continuous punching: This method uses a small perforated net mold to punch large holes.
5. Single forming: This method of forming a shape according to the mold once by shallow drawing.
6. Single punching: This method of punching through once, including linear distribution, circular distribution, circular distribution around the circumference, and grid punching.
7. Array forming: This method of processing multiple identical or different parts on a large plate.

If you need special-shaped perforated metal sheets, they can be laser cut after perforation. Laser cutting can cut perforated metal sheets into any shape. What problems will the perforated metal sheets encounter during cutting?
One, high cutting temperature. A lot of heat is generated during cutting, but the material of perforated metal sheets has poor thermal conductivity, so all the heat is concentrated in the cutting area and the blade, making it difficult to dissipate.
Two, difficult cutting. Perforated metal sheets are hard and have good plasticity and toughness, but during processing, cutting is difficult due to the difficulty of breaking and adhesion, which causes the metal sheet to be squeezed and worn on the surface of the blade, causing excessive wear of the tool (this is because the tool wears out, causing pits on the tool surface, forming small chipping and notches; perforated metal sheets have very high hardness, cutting directly with the tool and friction, scratching the tool, and the processing hardening phenomenon, all of which will aggravate the tool wear)， thereby deteriorating the surface finish of the perforated metal sheet.

Three, perforated metal sheets are strong and prone to deformation. During the cutting and machining process of perforated metal sheets, especially austenitic perforated metal sheets, there will be significant plastic deformation due to their certain elongation rate, which makes cutting and machining more difficult. Moreover, the perforated metal sheets themselves have a relatively high strength, which increases the dual resistance in the cutting process and enhances the cutting force.
Four, perforated metal sheets are prone to expansion. During the cutting and processing process, a lot of heat will be generated, causing the perforated metal sheets to expand, which makes cutting and processing more difficult.
