Extrusion International 2-2022

34 Extrusion International 2/2022 EXTRUSION TECHNOLOGY In detail, the high-speed line is capable, even in the most compact con fi guration, of producing up to 120m of tube per minute. Bausano, indeed, customises each plant based on the Customer’s needs, also with regard to the occupied ground volume, through innovative so- lutions aimed at reducing the size with the same pro- duction capacity. This unprecedented solution is based on a twin-screw extruder from the Nextmover MD 75/24 series, on which a specially designed stainless-steel head is installed. The cooling and calibration benches are designed with a idler system to reduce the overall dimensions of the line. In particular, ad-hoc idler systems allow for a threefold increase in the time the tube remains under water, thus ensuring greater ef fi ciency and extrusion speed, with an unrivalled fi nal tube quality. In this respect, compliance with tolerances, which are particularly tight in the medical sector, is guaranteed by a sophisticated detection system that accurately mea- sures the following parameters: diameter, ovality and wall thickness by laser and ultrasound, cross-section, shape and capacity of the tube, making it possible to rapidly reject non-compliant extrusions. Another distinctive feature is the Haul-Off Unit, which is equipped with a Control Panel that, when fi tted with the detection system, displays speed, measurement data and tolerances on the tube and its alarm systems. Furthermore, brushless motors, on request, help ensure even greater pulling accuracy for complete control of tube tension. Two types of accessories complete the line: the quick cutting system or the automatic wind- ers, whose speed is precisely controlled throughout the winding process. “The construction of an extrusion line for medical prod- ucts is always a very challenging project, especially when installing in limited spaces and it is necessary to down- size the plant compared to standard sizes,” states Gio- vanni Bausano, Head of the Technical Department, add- ing “Thanks to decades of experience, Bausano is able to respond with cutting-edge technological solutions to the most complex technical speci fi cations, in full compli- ance with strict international standards” and concludes “In this sense, the new high-speed line is an example of excellence, especially in terms of component customisa- tion, including the Industry 4.0 software, which can be con fi gured in the language of the end customer”. High Productivity in Medical Tube Extrusion Safe processes and utmost reliability: the medical industry sets strict criteria for the production of medical devices. Medical tubes, in particular, require the highest quality in terms of dimensional accuracy, surface type and complete absence of contamination. The new high-speed extrusion line for PVCmedical tubes by Bausano – a leading international player in the design and production of customised extrusion lines for plastics processing – meets the most stringent requirements, such as ISO 14644-1 Class 8 Cleanroom, thanks to the strict design criteria adopted, which also ensure high performance in terms of quantity and energy Bausano & Figli Spa C.so Indipendenza 111, 10086 Rivarolo Canavese (TO), Italien www.bausano.com
