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 PunchingWe 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 LevelingWe have 2.7 meters wide leveling machines, which enable perforated sheets to be as smooth as the original plates.Step 4 CuttingWe have advanced CNC plate shearing machines, which can cut perforated sheets to any accurate sizes you desire.Step 5 ShapingWe have advanced bending machines, which can bend perforated sheets to various shapes to meet your exact requirements.Step 6 PackingMany 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 IVMarginsMargins are the blank (unperforated) area along the edges of the sheet. For stock sheets, the standard is minimum margins along the length and no margins along the width.To specify other than standard margins, use the perforated round holes pattern quote form. Provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole) and the direction to which the margin is parallel (side or length dimension). Manufacturing considerations may affect margins. If the margins requested are not possible, the quote you receive will specify the new margins.Below is an example of a margin specification based on the illustration to the right:Margins:·1 inch margins parallel to both 25 inch dimensions·0.75 inch margins parallel to both 48 inch dimensions (To be continued)
