Twin-Screw Extruders with Energy-Saving Features

Italy’s Bausano (U.S. sales offices in Houston and Oswego, Ill.) has introduced its next generation counter-rotating twin-screw extruder lines to the U.S. and Canadian markets. Both the MD Plus and MD Nextmover series are aimed at PVC pipe, profiles, and wood plastic composites, among others.

The lines feature the company’s patented multidrive transmission system; a careful study of interpenetrating and counter-rotating screw geometry; and the newest motor generations and tools for consumption analysis, all of which are said to combine to deliver high levels of efficiency, durability, reliability and sustainability.

Compared to traditional systems, Multidrive’s innovative distribution of motion also reduces the likelihood of faults due to excessive stress on mechanical components, which 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.

The MD Nextmover line features an all-new Digital Extruder Control 4.0 system with a capacitive, multi-touch, panoramic screen. It performs continuous screening of the system by processing reports and graphs in real time to easily and precisely analyze extrusion parameters and consumption at each stage of the production cycle. MD Nextmover also includes an innovative Smart Energy System for contactless cylinder heating. By using an alternating electromagnetic field, the new system delivers a significant reduction in wear-and-tear while delivering energy savings of up to 35%.

Bausano will be participating at the Extrusion 2021 Conference, September 21-23, Rosemont, Ill.
