Precision Medical Tubing & Guidewire Measurement Systems

In medical tubing extrusion and inspection, small dimensional variations can quickly become product failures. Catheters, guidewires, and micro-extruded tubing require precise control of outer diameter, ovality, wall thickness, and concentricity, particularly in catheter shaft and guidewire components. Laser and ultrasonic measurement systems provide real-time dimensional data for extrusion control, laboratory inspection, and quality validation to ensure consistent product performance.

Medical Tubing Measurement & Inspection Systems

LaserLinc Triton 312 laser micrometer for diameter and ovality. This unit features an acrylic feed through guide.

Benchtop Diameter & Ovality Measurement

Laser micrometers measure tubing outer diameter and ovality with micron-level precision during extrusion and inspection. These systems provide continuous dimensional monitoring to maintain tight tolerances in catheter, guidewire, and medical tubing production.

OD/ID/Wall Measurement for Cut Polymer Tubing

Measure outer diameter, inner diameter, and wall thickness on cut polymer tubing samples in seconds. The BenchLinc OD/ID/Wall system provides fast, repeatable dimensional inspection for post-extrusion QA, validation testing, and process verification.

Full-Length Scanning for Catheters & Guidewires

Automated scanning systems inspect the entire length of catheters and guidewires while rotating the part. The Metron system generates detailed dimensional profiles across proximal, body, and distal sections with minimal operator influence.

OD/ID/Wall Measurement for Rigid Tubing

Measure OD, ID, and wall thickness on rigid and metallic tubing including hypotubes, nitinol components, and cannulas. The BenchLincUT system provides precise dimensional analysis for incoming inspection, validation testing, and laboratory measurement.

FlawSense laser triangulation system scanning tubing for dimensional defects and surface flaw detection

Surface Defect & Flaw Detection

FlawSense combines OD measurement with laser triangulation sensors to detect surface defects including scratches, gels, inclusions, and foreign material in real time. Ideal for inline extrusion inspection or final quality verification.

Tubing Part Holding & Fixturing

Secure and stabilize tubing during inspection using precision fixtures, roller guides, feed-through guides, and micrometer stands. Proper part holding improves alignment, reduces vibration, and ensures repeatable dimensional measurements.

Complete Tubing Extrusion Measurement

Control OD, ovality, wall thickness, and concentricity in real time during tubing extrusion. Integrated laser and ultrasonic measurement systems provide continuous feedback to extruders, pullers, and cutters to maintain tight tolerances in medical, catheter, and micro-extrusion applications.

Ultrasonic Wall Thickness

Use UltraGauge ultrasonic systems for in-line wall thickness measurement during tubing extrusion. Measure walls as thin as 0.001 in (25 µm) in polymers or 0.003 in (75 µm) in NiTi tubing. Not sure which transducer fits your product? Check them using our Ultrasonic Transducer Selector.

Diameter & Ovality Gauging

Laser micrometers measure diameter, ovality, and dimensional variation with sub-micron precision. Use as a stand-alone inspection system or integrate with PLCs for closed-loop extrusion control. Need help selecting reference pins for verification? Try our Calibration Pin Selector tool.

Offline OD/ID/Wall Spot Checking

Verify OD, ID, wall thickness, and concentricity after the tube has cooled and stabilized. Cut a short sample and measure it instantly with BenchLinc OD/ID/Wall. Send dimensional offsets back to the extrusion line through OPC-UA for process correction.

FlawSense laser triangulation system scanning tubing for dimensional defects and surface flaw detection

Inline Surface Defect Detection

FlawSense detects surface defects such as gels, voids, inclusions, and edge defects while continuously monitoring OD trends. Designed for catheter extrusion, balloon tubing, and medical micro-extrusion where visual defects and dimensional drift must be identified immediately.

Automatic Ultrasonic Transducer Alignment

AutoPilot automatically centers ultrasonic transducers on the tube to stabilize wall thickness and concentricity measurement during extrusion startup. Reduces manual alignment and improves repeatability for catheter extrusion, balloon tubing, and medical micro-extrusion lines.
