Near infrared spectroscopy for in-line monitoring during injection moulding

The application of near infrared spectroscopy to injection moulding is seen as a promising technique with several potential benefits: (i) productivity improvements, (ii) reduction of costs, (iii) real-time monitoring, (iv) improvements in quality control, (v) health and safety. Future developments of this technology would allow the closed loop control of injection moulding machines and the possibility of 'lights out manufacture'.
