Analysis MethodAn in-line near-infrared process control tool for monitoring the effects of speed, temperature, and polymer colour in injection moulding

In recent years, near-infrared spectroscopy has become a versatile analytical tool and has gained acceptance in a large range of production processes and industrial sectors, such as the petrochemical, pharmaceutical, environmental, biomedical and automotive sectors. This study demonstrates the potential offered by infrared spectroscopy for the injection moulding industry. It was found to be a useful tool, not only for in-line monitoring of polymeric materials, but also for in-line monitoring of the injection moulding parameters such as temperature and injection speed.
