Eccentric Presses for Stamping & Blanking: 10–250 Ton
For more than 40 years, Fresan has designed and manufactured the C-Frame Eccentric Press - our flagship line, exported across Europe since the 1980s and built from 10 to 250 tons across flywheel and back-geared models. The rigid, welded C-frame construction gives easy die access, a compact footprint, and stable ram alignment under load - suited to high-volume stamping, blanking, and punching. Every model is CE marked and built for continuous production use.
Flywheel Eccentric Presses: 10–40 Ton Capacity
The flywheel series runs on direct drive: the motor spins the flywheel, and the pneumatic clutch transfers that stored energy straight to the eccentric shaft. With no gear reduction in the drivetrain, these are the fastest presses in the line, cycling at 125 to 200 strokes per minute depending on model. That speed suits high-volume blanking, punching, and progressive stamping of smaller parts such as terminals, clips, and brackets. Strokes adjust from 0–40 mm on the FP 10P to 0–84 mm on the FP 40P, with the ram guided on four sliding surfaces. The 30 and 40 ton models have an open back with a clear front-to-back opening for scrap discharge; the 10, 15, and 20 ton models mount the flywheel and motor at the rear instead. An inclinable (tilting-frame) configuration is available on request.
Back-Geared Eccentric Presses: 60–250 Ton Capacity
From 60 tons up, a gear reduction sits between the flywheel and the eccentric shaft. The back-geared drive trades speed for torque, delivering the slower, higher-force stroke that heavier blanking, forming, and shallow drawing work demands. All models in this range are open-back presses with longer strokes and a larger ram and table area, giving progressive dies the space they need and working with press feeding systems for continuous production. The 60 ton model keeps the same ram guidance as the flywheel series, with four sliding surfaces. From 80 tons up, guidance steps up to eight sliding surfaces for greater ram stability under off-centre loads, and a hydraulic overload protector becomes standard, relieving the load instantly if press capacity is exceeded.

Everything below is standard on all 12 models, from the 10 ton flywheel eccentric press to the 250 ton back-geared unit. Fresan does not sell safety as an add-on: light curtains, interlocked guards, and the safety controller are part of the base configuration.

Optional Equipment
Every Fresan eccentric press can be configured to order. The most common additions are coil handling and press feeding equipment (decoilers, straighteners, and pneumatic or servo feeders) that turn a single press into a coil-fed line, plus upper and lower ejectors for automated part removal. For non-standard table sizes, Daylight, or control setups, Fresan engineers build to specification.
- • Additional worktable
- • Part ejector mechanisms (upper and/or lower ejectors)
- • Material feeding, loading & unloading systems (Decoilers, straighteners, pneumatic & servo feeders...)
- • Tonnage monitors & die protection systems
- • Die cushions (pneumatic, hydraulic, or servo-driven)
- • Special design
Built to European Safety Standards
Every Fresan press carries CE marking and is designed to meet the EU Machinery Directive (2006/42/EC), the Low Voltage Directive (2014/35/EU), and the EMC Directive (2014/30/EU) - covering mechanical safety, electrical safety, and electromagnetic compatibility as one integrated standard, not an afterthought.
Each machine ships with a full technical file and EU Declaration of Conformity, so the paperwork your safety officer or notified body will ask for is ready before the press reaches your floor. Light curtains, interlocked guarding, and a dedicated safety controller are standard on every model, from the smallest flywheel press to the largest back-geared unit - see Standard Equipment & Construction for the complete list.
What Is a Mechanical Press?
A mechanical press uses a motor-driven flywheel to store rotational energy, which is transferred through a crankshaft or eccentric shaft to drive the ram in a controlled vertical stroke. A clutch-brake system engages and disengages the flywheel from the shaft, allowing the ram to perform a single stroke or continuous cycles as needed, then stop precisely in position.
Compared to hydraulic presses, mechanical presses run at significantly higher speeds and lower cost per stroke, making them the standard choice for high-volume production - though they apply full tonnage only near the bottom of the stroke, rather than throughout the full range of motion like a hydraulic press.
Applications & Processes
Our mechanical presses are built to handle the core processes behind sheet metal production, from thin-gauge components to structural parts.
Blanking
Blanking cuts a flat shape from coil or sheet stock, the first step most stamping lines run. Small, high-volume blanks suit the flywheel eccentric presses, which cycle at up to 200 strokes per minute with no gear reduction in the drivetrain; larger or thicker blanks move up to the back-geared models, where tonnage headroom matters more than speed. Paired with a decoiler, straightener, and servo or pneumatic feeder, either series keeps blank supply matched to the downstream operations.
Punching
Punching creates holes, slots, or cutouts in a single stroke, often across multiple stations in a progressive die. Ram guidance scales with tonnage to keep that accurate: the 10 to 60 ton models guide the ram on four sliding surfaces, and from 80 tons up the ram changes to a substantially larger design guided on eight surfaces, distributing the load uniformly even on large progressive dies and keeping hole placement consistent station after station.
Stamping
Stamping forms sheet metal between matched upper and lower dies, and covers the widest range of parts we build presses for, from small brackets to automotive body components. It's the most demanding process for frame rigidity and ram guidance, since die alignment sets part accuracy directly, which is why every Fresan eccentric press pairs a heavy-duty welded C-frame with a CNC-ground AISI 4140 (42CrMo4) alloy crankshaft and a precision-guided ram.
Cutting & Shearing
Cutting and shearing separate sheet metal to size or profile, usually ahead of forming or stamping. The moment the punch breaks through, the load releases suddenly and sends a shock known as reverse tonnage (snap-through) back into the machine; the heavy welded frame is engineered to absorb it, protecting drive and tooling across high-volume runs. And since the cut itself happens in the last few millimetres of the stroke, the adjustable stroke lets you run the shortest setting that still clears the strip, lowering punch impact speed for longer tool life and freeing the press to cycle faster.
Bending & Forming
Bending and forming reshape flat sheet into angles, channels, or structural profiles, with the work happening higher above bottom dead centre than in cutting operations. That makes the point in the stroke where nominal force becomes available just as important as the peak figure, and it's exactly there that the back-geared drive delivers, developing nominal force well before bottom dead centre. The adjustable stroke lets you set exactly the travel the tooling needs: more of each stroke is spent forming rather than travelling, punch impact is reduced, and the press is able to run faster with a lighter load on the ram and drive.
Shallow Drawing
Shallow drawing forms a recess or cavity from flat sheet, such as housings, covers, or enclosures. Draw quality is speed-sensitive, so the AC inverter drive, standard on every model, lets the stroke rate come down to match how the material flows. Deeper geometries are possible too: in progressive or transfer tooling, each station draws the part one step closer to final shape, and every press stroke finishes one part with all intermediate forms made at once. Applications like that must be sized case by case against the eccentric press's force curve and available flywheel energy.
