Spotlight – Testing advancements
Natalie Daniels looks at the progression of product by testing and inspection
Instron, based in the UK, has launched the MPX Series for Charpy and Izod impact testing, designed for metal use. Suitable for high-volume testing, the capacities range from 300-900 joules. The equipment includes reliable data acquisition and reporting of absorbed energy using Fracta software. The MPX includes an automatic start for rapid testing, interchangeable hammer weights for the impact energy and an integrated guard and safety control system, approved by European CE mark and meeting ISO 13849 safety standards.
German company Lacerta claims to have improved testing standards, with its identiPol QA2 system, a plastic analyser designed to ensure that mouldable thermoplastics are tested for quality and consistency. It works by measuring thermal properties prior to processing. The QA2 takes a fingerprint of the material to calculate a QIS value to study the raw plastics against previously tested batches. Built-in diagnostics ensure samples are run in optimum conditions during a test time of around 15 minutes, to improve productivity within a compact unit.
One firm inspecting lighting tools is Maxxeon, based in Cleveland, Ohio. A UV inspection light, WorkStar 2003, has been produced with cordless portability for fluorescent magnetic particle testing and penetrant NDT of metals. It is designed to assess the quality of machinery in oilfield and chemical processing industries. At more than 13,000µW/cm2 intensity and with magnetic mounting capability, this tool is primarily for use by NDT technicians. The LED radiant flux has an 800mW emitter to generate a bright beam at 365–370nm that also works with all NDT fluorescent dyes.
Meanwhile, Aerotech, UK, is looking to improve accuracy during production and research. The MPS75SLE Series ball-screw stage with linear encoder offers high accuracy for applications in optics positioning, z-axis positioning of sensors in surface metrology and high-precision alignment. It features a 25nm resolution capability as well as a low thermal expansion of 3.3ppm/C. The motor includes a DC servomotor with a high-resolution rotary encoder or a stepper motor.
It is ongoing testing and inspection progressions such as these that will enable industry standards to continue improving.
