Introduction to types, specifications and punching methods of perforated metal

Perforated mesh types, specifications and punching methods
The raw materials used for perforated mesh are mostly: stainless steel, low carbon steel plate, galvanized PVC cold rolled coil, etc.
The types are divided into: pattern perforated mesh, formed perforated mesh, extra thick perforated mesh, extra thin perforated mesh, micro-hole perforated mesh, wire-cut perforated mesh, laser perforated mesh, etc.

Hole type specifications
The main specifications of perforated mesh include rectangular holes, square holes, diamond holes, round holes, oblong holes, hexagonal holes, cross holes, triangular holes, long waist holes, plum blossom holes, fish scale holes, pattern holes, eight-shaped nets, herringbone holes, five-pointed star holes, irregular holes, bulging holes, special-shaped holes, louver holes, etc.
1. Roll thickness 0.2mm-1mm, length 20m
2. Aperture 1.5mm-10mm
3. Sheet thickness 0.2mm-20mm; width*length ≤1.5m*5m
4. Aperture 0.5mm-200mm

Punching methods
1. Continuous punching in the same direction: using a rectangular perforated mesh mold to partially overlap processing, you can process long holes, trimming, etc.
2. Continuous forming: a forming method that is larger than the size of the perforated mesh mold, such as large-size blinds, rolling ribs, rolling steps, etc.
3. Cannibalization: a processing method that uses a small round mold to continuously punch arcs with a smaller step distance.
4. Continuous punching in multiple directions: a processing method that uses a small perforated mesh mold to process large holes.
5. Single forming: a processing method that shallowly draws and forms according to the shape of the mold. 6. Single
punching: punching is completed in a single time, including linear distribution, arc distribution, circumferential distribution, and grid hole stamping.
7. Array forming: a processing method for processing multiple identical or different workpieces on a large plate.
