Friction screw presses

The high flexibility of the FICEP PVX friction screw presses gives it a wide range of uses for different shapes and sizes of parts. This results in the technical and economical optimization in the hot forging of steel, brass and aluminum. These presses are also ideal for challenging applications such as coining and calibration.

Flashless forging

Coining

CLOSED RING FRAME

The energy and shock of the screw press is delimited in its closed ring-frame. Thus, the foundation requirements are minimal and the vibrations transferred to the floor are extremely reduced; in addition, the noise level is very low.

ROBUST AND PRODUCTIVE

The screw press design is very simple. This characteristic translates into sturdiness, high throughput rates and corresponding low maintenance costs.

POWERFUL

High energy levels available for each cycle results in a smaller screw press doing the same work of a much larger eccentric press (1.3 to 1.6 times larger eccentric press is required).

The absence of a bottom dead center eliminates the possibility of sticking the press when the material is oversized, too cold or misplaced. This also enables a sequence of several blows on the same part;

Energy levels can be preset easily and precisely thus optimizing energy consumption and production, regardless of the operator skills.

Pieces forged in one or two blows under a screw press require at least 7 to 8 blows under a hammer. This also means a reduced wear of the dies.

The screw press can be easily integrated in fully automated forging systems.
