The industry isn’t new to the so-called “out-of-autoclave” technologies as a necessary step towards high-volume manufacturing. Unlike other composites processing technologies, compression molding is capable of reproducing thermoset and thermoplastic composite parts in significant volumes, with the accuracy, repeatability and speed.

While many technologies are going full-electric, compression molding has not made this transition yet. However the advantages of electric over oleo-dynamic mechanisms will likely prompt this development. A key advantage of a servo-electric press is that, once the mold is clamped, energy expenditure is at its minimum. Hydraulic presses, on the other hand, must maintain hydraulic pressure throughout the pressing action.

Meccatronica Automazioni was established in the 1970s in Northeast Italy as a custom automation designer and builder achieving approximately 3.500 unique automation systems since then. In the early 2000s, new partnerships within the composite industry led to the development of the E-FORM line of servo-electric presses for compression molding with the purpose of overcoming the limits of the traditional hydraulic technology in terms of accuracy and efficiency.

servo-electric press uses ball screw jacks to convert torque developed by a brushless electric motor into linear and continuous force. The pressing action benefits in terms of:
position: positional resolution within +/- 0.01 mm (or +/- 0.0005 in), the highest precision rate of any machinery available today.
pressure: servo-electric presses are high-torque machines, they are able to achieve the required pressing force at any point throughout the stroke with infinite dwell capability.
speed: the constant amount of torque ensures a wide span of speed of the ram that ranges from 0.1 mm/sec to 80 mm/sec.
repeatability: since oil isn’t part of the equation, a single recipe can be replicated with homogeneous output regardless of oil temperature and viscosity.

Multiple cycle parameters, including temperature ramping, can be mixed into 80 different recipes that can be stored and recalled anytime, anywhere.

Full control of the pressing actions is achieved by a closed-loop feedback system. Instant feedback for diagnostics and data acquisition of multiple cycle parameters is provided at a rate of 1 sample per millisecond to ensure easy accuracy, repeatability and traceability.

Without oil tanks, hoses, pumps and hydraulic power unit, a servo-electric press is clean, requires low maintenance (electricity flow doesn’t wear out wires!) and low electricity, approximately onefifth compared to a hydraulic system.
