GRB manufactures mechanical components using fine blanking, conventional blanking, sizing, drawing, precision machining, prototyping, design and manufacturing of dies, assembly lines.

Grinding

Transfer blanking

Transfer blanking technology allows the effective machining of sheet metal without the typical constraints imposed by progressive dies (compliance with stages, little flexibility of the equipment, utilisation of the material).

This technology thus allows drawing, sizing and bending of metal components. It is a progressive blanking methodology carried out with independent dies, one next to the other. Special shaped grippers feed the components forward, in synchrony with the press movement. This technology offers a wide range of constraint-free applications.

Extremely complex components can be drawn, bent and cold-forged, with substantial saving of raw material and labour. However, the use of this technology is recommended only if large-scale manufacturing volumes are envisaged, due to the high cost of equipment.
