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 VI

Hole Pattern
Hole pattern is the arrangement of holes on a sheet-either staggered or straight rows. In a staggered holes pattern, the direction of the stagger is normally parallel to the short dimension of the sheet.
The standard pattern is 60° staggered. It is the strongest, most versatile, and economical pattern of the perforated choices. Also available are straight and 45° holes patterns, available by special order.
