Available Material Types: Low carbon steel, galvanized steel, stainless steel, aluminium and brass/copper/phosphorous bronze plate, etc.
Production Process
Step 1 Mold Design
The perforating process starts with the accuracy of mold design. We have every confidence in the top quality mold that is principally responsible for top quality perforations. Therefore in recent years, we have invested a lot of money in the mold design, and now we have seen our significantly increased capacity to construct molds. Tec-Sieve has owned several hundred sets of molds, so ordinary holes patterns will not necessitate the remaking of new molds, and these molds are available directly from our storeroom of molds.
Step 2 Punching
We have the state-of-the-art CNC punching equipment, which are of 16MT, 25MT, 40MT and 80MT types. The daily output can reach up to 1000 square meters. Based upon different material types, the plate thickness usually ranges from 0.1mm to 10mm.
Step 3 Leveling
We have 2.7 meters wide leveling machines, which enable perforated sheets to be as smooth as the original plates.
Step 4 Cutting
We have advanced CNC plate shearing machines, which can cut perforated sheets to any accurate sizes you desire.
Step 5 Shaping
We have advanced bending machines, which can bend perforated sheets to various shapes to meet your exact requirements.
Step 6 Packing
Many years of experience in the exportation of perforated metal has convinced Tec-Sieve that good quality products have to be companied by good quality packing, and in this way our clients can receive best quality products in the end!
Glossary of Perforated Metal (Take round-hole perforated sheet as an example)
Part I
Hole Center
Hole Center is the distance from the center of one hole to the center of the nearest hole in the next adjoining row. Holes center is one of two measures of perforation spacing. The other is open area. Because holes center and open area measure essentially the same property (perforation spacing), you need specify only one or the other, not both.
Open Area
Perforated sheets contain holes and material. Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent. In other words, open area describes how much of a sheet is occupied by holes. If a perforated sheet has 60 percent open area, then 60 percent of the sheet is holes and 40 percent is material.
Note: Specify either Open Area or Centers, but not both.
