MEDICAL TUBING | MATERIALS


A shot in the arm: recent


advances in medical tubing Vital in patient care, medical tubing can now be produced more accurately – and quicker – than ever before, thanks to advances in extrusion machinery and ancillary equipment


Medical tubing has become increasingly sophisti- cated, with ever-smaller tolerances required to meet the needs of manufacturers – and patients. Davis-Standard extruders have helped Vesta


Thermoplastics – a supplier of tight-tolerance medi- cal extrusions – to raise productivity. The company recently installed a Davis-Standard


MEDD extruder to add to its range of HPE extrud- ers. The MEDD has helped Vesta increase produc- tivity, alleviate potential backlogs and cut lead times for its portfolio of thin-wall tubing, multi- lumen, and coextrusion products. This includes tubing and devices that support single-use and long-term implantable applications such as neurostimulation, feeding and drainage tubes, catheters, and vascular loops. “We’ve had a lot of success with our HPE extrud-

ers, and the MEDD has been a welcome addition,” said Steven Mayol, senior process engineer at Vesta Thermoplastics. “Installation went smoothly and the MEDD is already proving a good investment.” The MEDD’s interchangeable barrel assembly,


ease of maintenance, and operator accessibility have been useful to Vesta. The design is specific to cleanroom environments, providing a replaceable feed section liner and direct drive technology for bottom line efficiency and materials flexibility, says Davis-Standard.
