PRODUCT REVIEWS
Precision forming presses
AIDA , founded in 1917 , develops and markets Direct Servo Forming ( DSF ® - Direct Servo- Former ) servo presses , installing thousands of units worldwide to date .
“ Our AIDA DSF ® servo presses offer unrivalled operability , even with a reduced number of forming stages . Thanks to the ‘ soft-touch ’ function , which causes the punch to slow down when it comes into contact with the material , these presses guarantee a significant increase in the overall quality of the parts produced without compromising productivity ,” commented the Italian press specialist .
AIDA has developed an energy-control architecture that replaces the kinetic energy storage capacity of a flywheel with the electrical energy storage capacity of capacitors . The peak electrical energy required during the forming phase is predominantly provided by the electrical energy previously stored in the capacitors , leading to power demand from the grid comparable to that of a mechanical press according to the press manufacturer .
“ All AIDA DSF ® servo presses use proprietary AIDA servomotors developed specifically for forming operations , offering five times the performance of a standard commercial servomotor ,” outlined AIDA .
At the beginning of 2021 , AIDA unveiled its new DSF-NE2 , a monolithic two-point servopress that combines the high rigidity of the monoblock frame with the flexibility of the freely programmable servo motion of AIDA DSF ® technology . The DSF-NE2 presses are equipped with AIDA ’ s high-torque , low-speed servo motor . Each frame component is designed and verified with FEM systems and is manufactured to reduce deflection under load to less than 0.1mm / m .
“ The DSF-NE2 series of presses guarantee multiple forming of various lengths , low noise and low vibration , optimising all production and maintenance operations while ensuring maximum application flexibility and long die life . This series of presses , capable of speeds of up to 120 strokes per minute , was awarded Product of the Year in the ‘ Stanz-und Umformtechnik ’ category at the EuroBLECH Awards 2022 in Hanover ,” confirmed AIDA .
The Blechexpo 2023 trade fair in Stuttgart ( 7-10 November 2023 ) will be an opportunity for AIDA to provide visitors with information on the DSF-NE2 series of presses and its entire series of presses ( including servo presses , high-speed presses for motor core lamination and precision forming presses ). These are suitable for the production of hightech e-mobility components such as bipolar plates , the cornerstone of hydrogen-powered cars .
For the production of EV / HEV engines , AIDA introduced its MSP series of highspeed lamination presses with a proprietary high-rigidity design and multiple suspension points in 2002 . It recently launched the MSP-3000-370 high-speed press specifically
The AIDA MSP series of high-speed lamination presses .

to handle moulds of up to 3,700mm long , as required for double-row production .
The new AET Electronic Transfer , the solution developed by AIDA for the after-market , enables the handling of parts and components in multi-station or interconnected presses . This will also be showcased at Blechexpo in Stuttgart .
“ AET transfer units integrate easily with all types of mechanical and servo presses from any manufacturer , and are perfectly suited for retrofitting to existing machines ,” concluded AIDA . n

Cutting and punching combi from coil
EffiCOIL is a coil-fed , combined punchlaser machine from Italian coil processing specialist , Produtech Srl .
“ The line is equipped with two compact and independent working heads ( electric
The EffiCOIL system . punching unit and optical fibre laser cutting unit ) running aligned , via an innovative electronic system . The units are perfectly synchronised and run on the same work area , with precision and speed . Processing from coil offers great production benefits and substantial cost , space and manpower savings ( eliminating all preliminary processes ),” Produtech explained .
“ EffiCOIL is an innovative and flexible solution in the coilfed , laser punching machine market because it cuts and forms coil sheets on a single line . Interpolation of the machine ’ s working axis allows it to cut , punch and form any shape or geometric figure for producing parts directly from coil . The technological value , innovation and environmental sustainability of this laser-punching machine were ratified by the European Commission , who financed the design and production of the first prototype via Horizon 2020 project funds ,” it added .
Produtech systems also include special equipment , such as punching lines for processing metal bars and beading machines , and a new AutoCOIL automation project . n
