extrusion industry patented technology multidrive system multidrive technology

The patented technology that raised the extrusion industry standards

Made-in-Italy quality and ongoing technology innovation: this is the perfect mix behind the exclusive patent for MD Plus and MD Nextmover twin screw extruders from Bausano. A perfect choice for several types of extrusion, pipes, granules, WPC, profiles and materials used in the medical industry, Bausano lines stand out for their unique transmission systems, a careful study of interpenetrating and counter-rotating screw geometry, the latest motors generation and consumption analysis tools, thus guaranteeing top production efficiency, sturdiness, reliability and sustainability.

“Multidrive system reduces stress on motor shafts, gears and screws thanks to the tightening torque strain being distributed on two pairs of motors”

Primarily, it is precisely the Multidrive technology that makes Bausano twin-screws unrivalled throughout the world. Evidence of years of research and experimentation, this transmission system undeniably reduces stress on motor shafts, gears and screws thanks to the tightening torque strain being distributed on two pairs of motors, resulting in higher power on screws, equal to the power delivered, with a positive impact in terms of both precision and energy savings. Compared to traditional systems, the distribution of motion also reduces the chance of faults due to excessive stress on mechanical components and ensures a longer average service life of the machine. Motors are managed by a single static frequency converter, an instrument capable of ensuring constant rotation and perfect synchronism, without using any additional devices.

In addition, the special multi-stage thrust bearings, designed to triple the dynamic load, enable the extruders to handle high production volumes. For smaller lines, on the other hand, Bausano has developed Multidrive 2x2, characterised by a single pair of motors, thus reducing overall dimensions and optimising the gearbox operation.

A wide range of innovations

Among the pluses of the lines, there is also the innovative Smart Energy System for cylinder contactless heating through an alternating electromagnetic field, resulting in a significant reduction in wear and energy savings of up to 35%. Finally, the new Digital Extruder Control 4.0, with its capacitive multitouch panoramic screen, performs continuous screening of the system by processing reports and graphs in real time, in order to easily and precisely analyse extrusion parameters and consumption at each stage of the production cycle.

“Each of our extrusion lines is the result of value engineering combining ongoing product innovation with extensive know-how - established in over 70 years - in plastic transformation processes” so Clemente Bausano, Vice President of the company, who continued “Along these lines, the Multidrive system has raised the standards in terms of service life and efficiency of machinery, undoubtedly becoming a technology reference point in the extrusion industry”. And he concluded: “An achievement obtained also thanks to the direct supervision of all design and development, as well as production, assembly and testing steps: an approach that makes it possible for us to ensure high technical and functional quality standards recognised by American and Canadian industry players”.
