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 III
Length and Width
Length is the overall measurement of the long side of the sheet; width is the overall measurement of the short side of the sheet. Note that mill tolerances for length and width apply to stock sheets unless otherwise specified. If you have a stock sheet cut-to-size, cut-tolerances apply. To specify other than standard tolerances, please use the perforated round holes pattern quote form to specify the required tolerances.
Quantity
Quantity is the number of full sheets or cut pieces you need. Unless otherwise specified, the standard tolerance on quantity is 'Exact Quantity'. In other words, Tec-Sieve will deliver the exact quantity you specify.
Bar Width
Bar width is the measure of the material between the outer edge of one hole to the outer edge of the nearest hole. If you specify bar width, be sure that the bar width meets the guidelines for minimum bar width.
