Extrusion International 4-2023

40 Extrusion International 4/2023 EXTRUSION TECHNOLOGY Extrusion Technologies for Medical Tubing Production Italian Tecno System is one of the leading brands in Italy about extrusion technologies for thermoplastic materials, involved in the manufacturing of customized turnkey systems such as extrusion lines complete with molds and integrated on-line or off-line solutions appositively designed to face any customer need. The company offers its customers a high level of experience, specific and consolidated know-how and constant R&D efforts combined with the professionalism of high-skilled team, in order to give clients the smartest solutions possible coupled with the top quality standard for after-sale services. A crucial business for the com- pany is represented today by the manufacturing of complete ex- trusion lines for medical tubes and medical pipes (single or multi-layer and radiopaco) exploited in phar- maceutical and hospital industries: thanks to constant efforts in quality control and rigid standards about internal and external processes, in facts, our plants result totally con- form to any national and interna- tional regulation about the matter. These extrusion lines are char- acterized by single screw extrud- ers equipped with special screws appositively designed for medical grade raw material such as Soft- PVC, EVA, TPU, TPE, PEBAX, etc. and they are suitable for a wide range of medical tubes and pur- poses. The basic medical extrusion line is usually equipped with ex- truders model TM 60-25 with 15” Touch Panel and a medical extru- sion head model HD 2-12. About downstream, there are a vacuum/ cooling unit model R 50/5,5, a belt haul-off unit model TT800 and an appropriate diameter gauge sys- tem (ODAC 14 x/y/j) that is entitled to ensure accuracy of the entire tube before being rolled up by a semi-automatic doble winding sta- tion model TS2600 endowed with electronic ultra-sonic dancer. Obvi- ously, there are alternative config - urations available for the customer, for example relying on extruder se- ries TM 75-25 or rolls haul-off unit, as well as the possibility to opt for numerous options like frosty kit, wall thickness monitoring systems, and many others. On this regard, it must be speci- fied that Tecno System extrusion lines are perfectly suitable also for spiral smoothbore medical tubes with rigid or semi-rigid spiral and also combining different polymers.
