Conventional blanking

Conventional blanking is the most versatile blanking procedure. Thanks to the combined use of feeding lines, presses and dies, all sorts of different mechanical components can be manufactured, such as bearing plates, closed boxes with bending and riveting, small drawn components, large and complex shaped plates complete with bending and threading.

Today, this technology has become so sophisticated that unprecedented operations, which were unthinkable of only a few years ago, have now become feasible.

It is now possible to make use of independent threading, drilling and bending units, in synchrony with the machine cycle. It is also possible to use state-of-the-art machines equipped with special kinematic mechanisms and further auxiliary equipment, such as air cushions, hydraulic cylinders, powerful gas springs.

The factors that make this technology extremely competitive are cost-effectiveness and repeatability induced by full automation and low costs of equipment manufacturing.
