Conair teamed up with extruder manufacturer American Kuhne and Zumbach Electronics, supplier of inline measuring, monitoring and control systems, to demonstrate close-tolerance extrusion of microbore medical tubing in Booth 1548 at Plastec West/MD&M West held on February 12 – 14 in Anaheim, CA.
Microbore tubing is used in precision products like heart and brain catheters.
Conair downstream extrusion equipment, like the MedVac vacuum sizing/cooling tank and Medline puller/cutter, in combination with online gaging and real-time control, can be critical to reducing wall thickness and ovality variation and maintaining the highest quality levels while using less material to make more tubing.
“Medical extruders have told us that their key to success lies in controlling process variables,” says Bob Bessemer, Conair Sales Manager, Medical Extrusion.
“This equipment not only gives them control of their process, so that they can make higher-quality tubing, it also gives them set-up and operation features that make their process more efficient so they can be more profitable.”
MedVac flood-cooling tanks from Conair have been specially designed to meet the needs of medical tubing manufacturers. Available in five models, the tanks can be used to make any size or configuration of tubing, from multi-lumen microbore heart and brain catheters to large-gage medical tubing.
The units include design elements that meet the stringent control, sanitary and operator-convenience requirements of precision medical extruders. These features include:
- Digital closed-loop vacuum control lets operators dial-in even extremely fine vacuum settings (within 0.1 inch of H2O) for better dimensional control;
- Cleaner interior design features, which virtually eliminate places where bacteria and pyrogens (bacterial cell wall fragments) can become lodged, result in more sanitary extrusion conditions;
- UV and 5-micron filters that provide medical-grade filtration of cooling water;
