Safe processes and the 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. Bausano’s new, high-speed extrusion line for PVC medical tubes 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.
High-speed medical tube extrusion line
In detail, the high-speed medical tubing extrusion line is capable, even in the most compact configuration, of producing up to 120m of tube per minute. Bausano customises each plant based on the customer’s needs, taking into account the occupied ground volume, with innovative solutions aimed at reducing the size but maintaining the same production capacity.
This unprecedented medical tube extrusion 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 tanks are designed with a unique 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 efficiency and extrusion speed, with an unrivalled final 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 measures 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.
Distinctive features of the medical tube extrusion line
Another distinctive feature is the drive unit, which is equipped with a control panel that, when fitted 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 winders, whose speed is precisely controlled throughout the winding process.
The construction of an extrusion line for medical products is always a very challenging project, especially when installing in limited spaces and it is necessary to downsize the plant compared to standard sizes.
Thanks to decades of experience, Bausano is able to respond to the most complex technical specifications with cutting-edge technological solutions, in full compliance with strict international standards. In this sense, the new high-speed medical tubing extrusion line is an example of excellence, especially in terms of component customisation, including the Industry 4.0 software, which can be configured in the language of the end customer.
