Perforating process

 

The perforating process starts by designing the precision die. We believe that the quality of the die is critical of the quaility of the product. We have therefore invested heavily in this area in recent years and developed our die making techniques.

Perforating

We use the CNC machine to produce state-to-art product. The day is over 3000 square meters. We can perforate the material thickness from 0.1mm to 25mm.

 

Sitting to your finished width is done in-line from a coil.

 

Our adept worker can shear the margins when the tolerance is greater than our in-line process.

 

We can bring the perforated material thichness arrange from 0.8mm-12mm back to the original flathness with the roller process.

 

The perforating process requires the use of lubricants, and a degreesing step can be applied to clean oil free from the material surfaces.

 

Besides custom perforating, we also offer a full range of in-house and out-soured secondary fabricating and finishing operations, which include: leveling, shearing, circle shearing, bar coding labeling, custom packaging, degreasing, deburring, forming, blanking. Annealing painting powder coating, anodizing, welding, polishing, joining, bending, rolling.

 

 

Perforating, leveling and shearing normally leave slight surface imperfections behind that are considered acceptable in the industry. If required, special precautions such as vinyl coted material and paper interleaving can be taken, at additional cost.

 

We probide a brief guide to help you understand the nomeclature used for the specification of different types of perforated sheet.

 

We can provide you the following material: stainless steel, carbon steel, zinc, galvanized, aluminum, brass, copper, plywood, fiberboard, rubberborad, woodboard, pasteboard, AL-MG, alloyplate, nickel-plate, fiber, glass, PVC, plate, composites.

 

We can manufcture a wide range of thick sheet verifying from 0.1mm to 25mm. Length is overall measurement of the short side of the sheet. The standard sheet size is 10000mm*2500mm. The coil width 1000mm is also available. We also can process the special product for your requirement if you tell us the exact specification.

 

Round, square, long round, triangle, scale, diamond, oval, hexangular, slot etc.

 

In general it is advisable to use a hole size larger than the material thickness. The closer the hole size and material thickness come to a 1 to 1 ratio, the more difficult and expencive the process is. Deperndent on the material type, smaller hole size to material ratios can be achieved. The minimum diamter we can fabricate is 0.003’’ (0.08 mm ). If you require a die that isn’t already in our die bank, our experienced tool and die makers can quickly make exactly what you need at a reasonable cost.

 

We have tooling available for many different hole patterns and shapess. It is more economical to choose the available patterns, although special hole sizes and patterns can be accommodated at additional cost.

 

Hole center is the distance from the center of one hole to the center of the nearest hole in the next adjoining row.

 

Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent. Keep in mind that punching holes in a material add stresses that can result in distortion of the product. The higher the open area, the more material distortion takes place, especially when the perforated pattern is bordered by margins on all four sides. But these distortions can be removed by our special in house leveling process.

Margins

Margins are the blank area along the edges of the sheet. If you want the product with special margins, you should provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole). Manufacturing considerations may affect margins. If the margins requested are not possible. We will replace it with the similar products as your consideration.

 

There are tolerances on thickness, pitch, openings, flatness, and shearing for perforated products. You should specify a specific tolerance, so we can give you a precise product. If not, we will according to standard tolerance.
