The screw presses manufactured by F.T.B. are based on tried and tested designs that can be customised to meet the customer’s needs. 

The structures can be composite in steel or ductile iron, or some models may be made completely of electrowelded iron. The structures are then assembled using hardened and tempered steel tie rods.

One of two different kinematic systems may be used for their operation: - traditional (CF range) with roto-translational motion of the flywheel and screw; - mobile bushing (CM range) rotational motion of the flywheel and screw combined with translation motion of the screw nut joined with the ram.

The control disks may be integral or independent for more accurate control during the up and down stages. The ram stroke and size of the work area can be purposely designed to meet the machining requirements.

All of the parameters such as the stroke, power, number of blows, etc can be set and adjusted easily from the electronic control board to obtain the best performance and consumption from the press.

Screw presses combine the advantages of hammers and eccentric presses with the added benefit that they offer a considerable degree of power (to perform the same job you would need an eccentric press of about 1.3 times greater or with a hammer you would need to more than double the number of blows), a considerable number of adjustment options and are based on a simple construction concept.
