Down the line: latest in downstream equipment
Recent innovations in downstream equipment – which can be seen at this year’s K2016 – include a non- contact device based on millimetre wave technology. Lou Reade reports
In the lead-up to next month’s K2016 show in Dussel- dorf, it is no surprise that suppliers in every discipline are adding to their product lines. In downstream equipment – which includes everything from cooling baths to haul-offs – there is a strong focus on devices that measure part dimensions. NDC Technologies, for instance, will exhibit its latest
integrated gauging system for in-process measurement and off-line part inspection of plastic pipes and tubes. Its Beta LaserMike system integrates laser diam-
eter, ultrasonic wall thickness, fault detection, and laser length and speed measurement technologies to automatically monitor and control pipe and tube dimensions during production. This enables manufac- turers to raise product quality, increase productivity and make production savings. Its new AccuScan 6000 series of four-axis gauges includes the AccuScan 6012 for measuring products up to 12mm, and AccuScan 6050 for measuring products up to 50mm. Both provide high ovality accuracy (up to 100%) and fl aw detection accuracy – with a 25% improvement over three-axis measurement methods. This is done through ultra-fast diameter and ovality measurements at 9,600 scans per second, coupled with single-scan repeatability down to 1 micron (for the AccuScan 6012) and 2 microns for the AccuScan 6050. It will also display its UltraScan ultrasonic gauge
that provides non-contact precision measurement of product wall thickness and concentricity. UltraScan’s patented ‘Snap Technology’ automatically sets up the waveforms of all transducers, tracks tolerances to

catch wall variations, and provides average wall and concentricity measurements with high accuracy and repeatability. This allows pipe and tube manufacturers to make instant process adjustments to avoid scrap and boost quality. The latest three-axis LN3015/LN3040 lump and
neckdown detectors spot product fl aws before they become costly production problems. Fast-sensing, processing technology instantly detects sudden changes in the product diameter (up to 15mm and 40mm) to catch the smallest of fl aws.
Also on display is the LaserSpeed non-contact gauge
for measuring the length and speed of products. It delivers better than +/-0.05% accuracy and +/-0.02% repeatability, making it an ideal replacement for contact encoders – which are error-prone and high-mainte- nance, says the company. For off-line sample and cut-part inspection, NDC will show the latest version of its BenchMike measurement system, which now has a larger high-resolution display.
Millimetre precision Sikora, meanwhile, has developed a new technique for measuring pipe dimensions, based on millimetre wave technology. The concept, developed in cooperation with the
Fraunhofer Research Institute for High-frequency Physics and Radar Technology (FHR) and the South German Institute for Plastics (SKZ), allows precise, non-contact online measurement of inner and outer diameter, ovality, wall thickness and sagging of large
