Our CNC operated punch presses use a tool and die containing punches to stamp out a series of holes, producing your required perforated pattern.
Our large range of differently shaped and sized punches allows you to create a unique arrangement. The coil fed presses with dedicated levelling machines have the ability to perforate across the whole sheet, making this the most efficient production method.
Coated and composite materials
Using the perforating method, the smallest hole size we can produce is just 0.8mm. However, if an e-coat is required, we recommend going up to 1.2mm, to prevent the holes filling with the paint.
FREE AREA CONFIGURATOR
The size of the holes and the spacing between them influence the free area. This affects the acoustic performance, visual aspect and rigidity. The configurator aids the process of the free area selection in conjunction with your desired shape size and bridge gap.

Our latest computer CAD software and 3D modelling allows us to turn an image into perforated art. Through the software's light and dark detection system, a perforated image can be generated solely using different sized holes. From a simple logo design pattern to Michelangelo's work, we can turn a standard grille into a piece of art.
