Sikora’s X-Ray 6020 Pro is designed for measuring medical tubes
Onyx Hose & Tube of Canada makes medical tubing for oxygen delivery systems and ventilators, which have been supplied to field hospitals in Central Park in New York City. It uses NDC’s AccuScan and BenchMike devices
to measure the diameter and ovality of its products. A second NDC customer, based in Massachu-
setts, USA, was also increasing production of its medical product when its BenchMike device stopped working. NDC delivered a new unit – from its nearby Connecticut facility – the same afternoon. It also collected the broken unit – and repaired and returned it the next day. “The customer was able to resume production, thus doing their part to help with the pandemic crisis,” said NDC.
Quality control Sikora supplies a number of measuring and control devices for quality control during the extrusion of medical tubes. Two critical characteristics of medical tubing
that manufacturers need to track are dimensions and surface quality. Single or multi-lumen col- oured tubes, which require accurate measurement of outer diameter and ovality, can be checked with a device from the Laser 2000 XY series. Three-axis models, such as the Laser 2010 T,
offer high precision for transparent medical tubes, while an alternative series – Laser 6000 – offers a higher measurement rate, while also detecting lumps on the surface of the tube. The thickness of single-lumen medical tubes can be measured during production using the X-Ray 6020 Pro. The X-ray measurement system is designed for smallest medical tubes with diam-

eters of 0.65-15mm and a minimum wall thickness of 0.1mm. The system continuously records data about wall thickness, eccentricity, inner and outer diameter and ovality. The device can be combined with a three-axis lump detector: the Lump 2000 T gauge heads detect small irregularities on the product surface after cooling. Devices can be integrated into horizontal or vertical extrusion lines.
Sample measurement Sticking with medical quality, US-based LaserLinc has introduced its Metron-L sample measurement system. Metron-L is a measurement tool for parts that
require precise, accurate diameter measurements over an assigned length, says the company. This is critical when measuring articles such as coronary catheters and guidewires. Samples are loaded into the Metron-L system
and, at the touch of a button, measured automati- cally. Results are displayed, trended and recorded for future reference and compliance. The system allows precise, customisable off-line
measurement of cylindrical parts. It can measure parts up to 72in (1.8m) long and diameters from 0.004-1.18in (0.102-30mm). It is compatible with the Total Vu HMI platform, allowing easy visualisa- tion of product dimensions and profiles. It also features Statistical Process Control (SPC) and data logging.
