Bausano Debuts Twin- and Single-Screw Extruders for PVC and Polyolefin Pipes
Italy’s Bausano announced today the launch of its next generation twin- and single-screw extrusion lines for PVC and polyolefin (PO) pipes. The twin-screw MD and single-screw E-GO lines enable the production of different types of pipes — rigid or flexible, mono or multilayer, smooth or corrugated — for construction, agricultural, medical, and other applications.
“Expansion of our extrusion lines for PVC and PO pipes is the result of our unique ability to combine our technological expertise, process consultancy with customers, and our passion for innovation,” said Bausano Vice President Clemente Bausano. He noted that the company recently added members to its technical team with specific skill sets for designing advanced extrusion equipment.
A high-performance extrusion line for PVC pipes in diameters ranging from 63 to 160 mm, the MD Nextmover 170/30 model is equipped with a double-exit die head and achieves an overall throughput of 2,000 kg/h. The gravimetric doser is designed to ensure maximum precision so the pipes in out feed weigh the same. In addition, the 170/30 model features bimetallic screws and a cylinder that are less prone to corrosion and wear.
The system also includes:
- Stainless-steel cooling and calibration benches;
- two 9-m parallel calibration benches in a two-chamber configuration with temperature and water level control, allowing different vacuum conditions, as required;
- a space-saving, high-performance pipe cooling system — quicker cooling improves pipe quality;
- end-of-line drive systems, cutting units, and belling machines are available as accessories.
The MD and E-GO lines are powered by Bausano’s Smart Energy System based on electromagnetic induction, which enables more rapid and uniform heating of the cylinder, achieving up to 35% in energy savings, according to the company.
The Digital Extruder Control 4.0, with a 21-inch screen, monitors consumption at each stage of the process and displays performance in real time, allowing the user to manage motor power, temperature, oil control unit inspection, screw adjustment, and other parameters, on request.
Bausano’s extrusion lines meet “smart factory” vertical integration requirements and are compatible with third-party systems such as in-line measurement tools to control the pipe’s internal and external diameters and wall thickness.
Founded in 1946, Bausano’s headquarters are located near Turin, Italy, and it has production units in Brazil and India. Its US offices are based in Oswego, IL, and Houston.
