Continuous Development

Rotoplastic continues the evolution of rotational moulding machines. The goal is to create competitive and high quality machines.


On the side of the producer and the environment. Our machines, built with the latest technologies, have superior quality and are designed to increase productivity by reducing consumption, less waste, greater attention to costs and the environment. The structure is made with metal profiles and high efficiency insulation panels.

The insulating panels are made of high-strength steel sheets, the insulation is composed of mineral fiber made with wet-felt technology and ceramic fiber with a limit temperature [°C] 1100 for a total density of more than 180 kg/m³. To ensure excellent thermal insulation, the total thickness of the insulating panels is 115mm. In fact, when the operating temperature inside the oven reaches 330°C, externally the walls don't exceed 40°C (with an ambient temperature of 25°C).

Thanks to our speed control algorithm connected to the chamber pressure and the air temperature, the ventilation of the air in the molding chamber is dimensioned with electrical powers that are 70% lower than the old generation machines, our system has allowed us to use a parallel axis gearmotor so as to completely eliminate power losses on the transmission, thanks to the high efficiency inverter and the IE3 motor, electrical consumption is minimized our control system allows to reduce the total electricity consumption of the molding chamber by an average of 50% on the lower hourly average of machines of the same series produced to date.

Booms with high capacities and unmatched technology! The motors are all IE3 according to the European directive 2005/32/EC.

The nominal frequency of the gearmotors is 87Hz which, thanks to the new Motec 8400 inverters, allows energy savings of 30% less than machines of the same size.

The motors are controlled via the high-speed Profinet field bus, the Profinet system allows you to obtain the instantaneous absorbed current and optimal management of the speed from the inverter.

Thanks to an encoder, the axis speed is precise and linear regardless of the load, this allows the elimination of motor sliding and an accuracy comparable to positioning systems with synchronous motors.
