Further processing of perforated metals

Following processing techniques are followed to provide the high quality end perforated sheet metal:

Leveler

The Perforation metals punching process causes technically inevitable plate stress or deformation. The leveling needs are based on the kind of perforation and the perforation or non-perforated regions. Subsequent to perforation, any stress is discarded by flattening the plates in the particular leveling devices.

Plate shear

Cutting a perforated plate is essentially a complicated technical task, because pattern and the position of the holes are to be considered. Straight cutting with a plate shear is an affordable solution. We use laser cutting apparatus that provides the highest precision and the most complex of cutting contours.

Folding press

The bent components can be made on a CNC folding press. Even complicated bent profiles can be produced by using this machine. Bending and edging are only two of the various shaping methods we provide for perforated plates.

Welding

Heanjia SuperMetals always employ the significant welding methods for the operation in hand. Our highly trained and quality welders deliver high quality components as per your technical drawings.

Surface

In the perforated method, fine burns on the edge portion of the punch are sometimes unpreventable. These can be eradicated or reduced by using specific grinding,mechanically polished, electro-polished and sand or glass bead blasted.

Rounding

Another perforated plate processing technique followed is rounding using three to four roller rounding machine. Specifically challenged bends can also be made affordably.

Hole patterns

For technical reasons of tools, punches and dies in the tools are set further apart than the bridges among the holes in the perforated plate themselves. The initial press stroke creates a hole pattern with unfinished rows, the second press stroke completes the hole pattern. If the complete hole pattern is needed on the initial press stroke, it can be provided separately.

Screening Direction

The screening direction is the adequate direction of separation or screening,taking the hole pattern into account. The closest feasible hole pattern is 60o.It results in a specific direction in which the sheet being screened is forced by the hole. This screening direction produces the most workable screening outcomes. The screening direction is particularly essential in the bulk material processes.

Count of holes and free area

The count of holes and free area needed are generally the crucial factors in choosing the adequate manufacturing method. It is because the cross-section area of a perforated screening plate is chosen by the opening area and therefore by the throughput while the whole process.

With significant knowledge, we employ the perforated plates that are optimized to fulfill our customer needs precisely. The punching technique is limited by the critical ratio that is explained later,which we are capable to overcome by using the high tech manufacturing processes. These methods not only allow the excellent feasible perforations in the thick plates,but also a vital improvement in the free area of the punched screen.
